PERFORMANCE OF TOBACCO VARIETIES IN NORTH CAROLINA

John C. Rice, Glenn Hayes and Ernest L. Pricell

As of November 28 the 1977 flue-cured tobacco production in North Carolina

was estimated to be 717 million pounds. This would be 19% less production than

in 1976 when the estimate was 865 million pounds.

The 1977 total was produced on 382,000 acres with an average yield per acre

of 1877 pounds. This was 135 pounds less per acre than last year's average

yield.

Production of flue-cured tobacco in the United States was forecasted at

1119 million pounds or 197 million pounds below the 1976 production. This was

15% below last year's production.

Dry weather at planting time, heavy rains during early growing with some

damage from drowning, plus a hot, dry summer resulted in less poundage during

1977.

The year 1977 represents the fourteenth year in testing new tobacco

varieties as required under the Minimum Standards Program. This program,

started in 1964, has continued to make available flue-cured tobacco varieties

with acceptable agronomic characteristics and well-balanced physical, chemical

and smoke properties. Special attention has been given to maintaining those

new varieties with acceptable flavor and aroma characteristics.

The minimum standards serve as a gUide to breeders in developing new

varieties that will be acceptable to the trade. It is a voluntary program

that has been enthusiastically endorsed by all segments of the tobacco

industry. The program adopts the principle of testing new varieties against

standard varieties. New varieties should be genetically stable and should

not differ from the standards, NC 2326 and NC 95, by more than plus or minus

specified percent for measurable chemical traits. The acceptable range for

nicotine is plus 15 percent and minus 20 percent of the mean of NC 2326 and

NC 95. New varieties should not contain more than eight percent of the total

alkaloids as nornicotine and limits are set on nitrogen and sugar contents.

Variety candidates should compare favorably with the standard varieties for

color, body, texture, moisture equilibrium, filling value, flavor and aroma.

A minimum of two years evaluation throughout the flue-cured region of the

United States on both experiment stations and farmer plots is required.

Such a program means much to our domestic and export trade and to growers

because it assures the manufacturers that new varieties will have been

thoroughly tested and evaluated for agronomic, pathologic, physical, chemical

and smoke characteristics. Quality is the one factor the American farmer has

to sell and the Minimum Standards Program should help to assure that quality

is continuously improved. Varieties playa determining role in quality and

should be carefully selected by the grower. The following varieties have been

released under the Minimum Standards Program:

The Tobacco Variety Evaluation Program in North Carolina is a part of the

Regional Test. Data are presented from the 1977 Official Variety Tests in

North Carolina and the 1977 Regional Farm Tests. In addition, a summary table

of variety performance over different years and locations is presented. Similar

reports which record previous years' data have been issued. Testing over a

period of years and under farm conditions is needed to fully evaluate the

performance of any variety. Information of this nature serves as a guide to

tobacco breeders in the development of varieties and to growers in choosing a

variety.

Experimental Procedure

The Tobacco Variety Evaluation Program in North Carolina is divided into

three phases. The first phase, the Official Variety Test, consists of testing

varieties and breeding lines in small replicated plots located on five research

stations. In 1977 a total of 49 entries were included. The second phase is

the Regional Small Plot Test, conducted in five states, and these data are

presented in a separate bulletin--Flue-Cured Tobacco Variety Evaluation

Committee Report. The third phase of the program involves a more extensive

study of fewer varieties and advanced breeding lines grown under farm conditions

in approxtmately one-fourth acre plots and is referred to as the Regional Farm

Test. Six entries, including the two standard varieties, were tested in 1977.

There were eighteen varieties and thirty-one breeding lines The map in Figure I shows the locations of these stations and also the

Regional Farm Tests.

Methods

The Official Variety Tests were conducted on disease-free soil, insofar

as possible. All entries were coded in the plant bed and in the field and

were included at each location.

Three replications of a randomized block design were used at each

location.~/

included in the tests for a total of 49 entries. The plants were individually

selected at transplating for maxi~mumuniformity within plots at all locations. Each one-row plot consisted of 20 competitive plants. The rows were four

feet apart at all locations except Reidsville (3.75), and hills were spaced

22 inches apart. Cultural practices are shown in Table 18.

After topping, all entries were treated with Off-Shoot-T followed by

Royal MH-30. Individual plots were harvested according to degree of maturity,

tagged and kept separate throughout curing, sorting and grading.

~/Statistical

analyses were made in the Computing Center under the

superv~s~on

(8)

Data on agronomic characteristics were taken in the field, and chemical

determinations were made on the cured leaf of the whole plant. Disease

reactions were noted in separate tests under severe disease conditions.

The methods of recording data were the same as those used in previous

years, except as noted, and may be found in Crop Science Research Reports

Number 12 (1964), Numb e r 16 (1965), Number 20 (1966), Numbe r 24 (1967), Number 28 (1968), Number 32 (1969), Nmber 36 (1970), NtUIlber 41 (1971),

Numb e r 44 (1972) , Number 48 (1973), Numb e r 53 (1974) , Number 56 (1975), and Number 59 (1976).

Value per Acre: After the tobacco was sorted into lots, a Federal Tobacco

Inspector graded the tobacco from each plot into appropriate government

grades. The value per acre \vas calculated by multiplying the pounds of each

grade by the average auction price paid for the grades during the 1976 and

1977 seasons for types 11, 12, 13 and combined through September 16, 1977.

Grade Index: Beginning in 1974 each entry was rated with a grade index

ranging from 0 to 99. This index resulted from placing a numerical value to

each government grade for varying stalk positions of each entry. A weighted

value was obtained for each entry which provided an overall index. Grades

N2 and A1F represent the practical extremes with values of 0 and 99 assigned

to these respective grades.

Value per Cwt: The dollar value per hundredweight for tobacco sold during

1977 was a record high with small variations between leaf grades. The market

value of low stalk tobacco was lower than cutter or upper stalk grades. The

value per hundredweight listed shows little difference between entries.

Seasonal Conditions: The transplanting of tobacco at all five locations of

(9)

Early growing conditions were, in general, favorable with good stands reported at all locations.

The Whiteville Test, TV 263, was transplanted on April 18. Rainfall in

April was very low at .99 inches, therefore, the crop made a slow start.

Rainfall for the remainder of the year was: May 4.90, June - 4.32, July

4.19 and August 6.68. The season was normal for a good tobacco crop and it

matured normally resulting in a good crop of tobacco. The fertilization

program was 700 pounds per acre of 6-12-18 and 135 pounds of 15-0-14 used as

a topdressing.

The Kinston Test, TV 264, was transplanted on April 27. Rainfall during

the growing season was: May 5.70, June 4.15, July 2.58 and August - 6.49

The fertilizer grade, 8-16-24, was used in amount of 500 pounds per acre with

350 pounds of 15-0-14 used as a topdressing. The tobacco in this test tended

to be fair in color and had thin to medium body with fair texture.

The Rocky Mount Test, TV 265, was planted on May 4 under good moisture

conditions and seasonal growing conditions were favorable for producing a fair

to good crop on this station. Tobacco from this location was of fair quality

and texture. Fertilization consisted of 1050 pounds of 4-8-12 plus 370 pounds

of 15-0-14 used as a topdressing. Rainfall during the growing season was as

follows: May - 5.62, June 3.07, July - 3.37 and August - 4.32.

The Oxford Test, TV 266, was transplanted on May 2 under good conditions

and seasonal conditions were favorable for a good crop. Rainfall during the

growing season was as follows: May - 5.30, June 2.73, July - 5.23, including

three inches of irrigation, and August - 5.54. The crop was fertilized with

600 pounds of 8-8-24 and 147 pounds of 15-0-14.

The Reidsville Test, TV 267, was transplanted May 9 under good moisture

(10)

was as follows: May - 2.64, June 2.58, July 4.94, including three and

on-half inches irrigation, and August - 1.46. Overall the quality of the

entries was fair to good in this test. The crop was fertilized with 800

pounds of 6-12-18 plus an additional 175 pounds of 15-0-14 as a topdresser.

Regional Farm Tests

The number of entries in this test is necessarily limited since the plots

are rather large and there are many locations. This program includes advanced

breeding lines that have met the minimum standards in the Regional Small Plot

Test. It is desirable to gain information on these breeding lines and varieties

under farm conditions. Also, this provides an opportunity for the tobacco

companies to study the breeding lines and new varieties for their manufacturing

characteristics.

This part of the evaluation program is a cooperative effort of the

experiment station, extension service, USDA, tobacco companies and growers.

The participating companies were: The American Tobacco Comfany, Brown and

Williamson Tobacco Corporation, Imperial Tobacco Company, Liggett and Myers

Tobacco Company, Philip Morris, Inc., P. Lorillard Company, R. J. Reynolds

Tobacco Company, Export Leaf Tobacco Company and Universal Leaf Company.

Thirteen locations were planted--two in South Carolina, two in Georgia,

three in Virginia and six in North Carolina. This is a cooperative program

and permission was granted for the inclusion of all locations in this report.

Fertilization and other cultural practices, as shown in Table 17, were

those generally used by the growers. A nematode assay was made on all fields

and those with a nematode problem were fumigated. Only information on the

North Carolina tests is shown here.

Representatives from both domestic and foreign buyers visited these plots

(11)

participating companies to examine and sample for laboratory analyses. Each

company graded the tobacco according to the types they normally use in their

manufacturing. In addition, they also rated each lot of tobacco for its

physical quality characteristics according to color, body, texture and usability.

Displays were scheduled in 1977 at Kinston and Roxboro, North Carolina. Other

displays were scheduled in Georgia, South Carolina and Virginia for physical

characteristics evaluations.

MOst of the locations received adequate to excess moisture in producing

their crops. Generally, the growing conditions were favorable for the crop.

Edmund transplanted on April 14 under moist soil conditions and had adequate

rainfall during the growing season. The quality of the crop was good.

Sutton and Hooten transplanted on April 18 under good soil moisture. All

entries transplanted and grew off well. Rainfall from April to August was not

adequate and not spaced properly for good crop growth. The crop was of fair quality

Harrell transplanted on April 23 and 26 under good conditions. A good

stand was obtained and grew well under favorable conditions with excess rainfall

causing the crop to drown.

Andrews transplanted on April 26 and May 9. Tobacco grew off good with

adequate moisture but had a dry June and July and he irrigated once. This crop

was fairly thin to medium bodied, lemon colored and fair quality.

Dickerson transplanted on May 10 and the crop grew off well in the field

but had a very dry June, July and August. Under these dry conditions, the

tobacco tended to be heavy and dark colored. He irrigated his crop once.

Day transplanted on May 2 under good moisture conditions. He irrigated

four times because of dry conditions. The quality of this crop was good.

All six cooperators used Off-Shoot-T contact sucker control material

(12)

controlling suckers. This procedure allowed early testing of potential

varieties with these growth regulator materials.

Results and Discussion

The data are discussed under the headings (1) Official Variety Test and

(2) Regional Farm Test. Individual location data are presented but are

discussed only to emphasize specific points.

Official Variety Test

The data presented in Tables I and 2 are summary data from various years

and locations and indicate how several varieties have been performing over a

period of years at various locations.

In Table 1, data are presented to show a comparison of the mean of

NC 2326 and certain flue-cured tobacco varieties. Yield, acre value and grade

index are based on a three-year average (1975-1977).

In Table 2, varieties that were common in the 1975, 1976 and 1977 tests

are compared for a large number of characteristics. The same general trend

was shown in these varieties during all years. Coker 48, Coker 86, McNair 944,

NC 13 and NC 89 had the highest yicl~per acre. These five varieties also had tre highest values per acre. NC 2326 was the earliest to flower. All varieties

had about average percent nicotine, ranging from 3.25 for Speight G-28 to 4.15

for NC 13. All varieties were in an average range for other chemical and

agronomic traits.

Table 3 shows the percent of tobacco harvested at each priming. It also

shows the accumulated total harvested through each priming. This information

can be used to get an idea of the relative rapidity that a variety comes off

the stalk. Under the harvesting schedule most all varieties matured equal to

(13)

The average performance of varieties and lines compared at five locations

in 1977 is shown in Table 4. There was some variety x location interaction

for the characters studied, however, it probably was not sufficient to affect

the choosing of a variety to plant. Varieties tended to perform the same

relative to each other, that is, they did not make major shifts. The variety

x locations mean squares were used for computation of L.S.D. values. The

entries shown at the top of Table 4 are commercially available varieties,

whereas, those in the lower portion are breeding lines.

Commercially Available Varieties

NC 2326 was below the mean of the yield for the eighteen varieties in the

test. The dollars per hundredweight ranged from a low of $118.94 for Coker 86

to a high of $124.76 for Coker 319. This highest value per acre was Coker 48

at $3697 per acre. The grade index ranged from a low of 32 for Coker 86 to a

high of 42 for Coker 319, McNair 944 and Speight G-28. A small variation in

this data is significant. Considering all entries in the test, there has been

a high correlation between the value per hundredweight and the grade index,

indicating that the two are giving a somewhat similar picture. If the tobaccos

are normal in physical appearance that would be expected.

Most varieties were intermediate in their flowering habit, ranging from

one to five days later than NC 2326. All varieties were evaluated for the

number of leaves per plant. NC 98 had the highest ground sucker count.

Quality is divided into visual or physical appearance, chemical

character-istics and smoking charactercharacter-istics. The visual characteristics can be readily

seen by the eye, whereas the chemical and smoke characteristics must be

determined in the laboratory. Data on several chemical constituents that are

(14)

to have satisfactory chemical composition with Speight G-28 being the lowest

in nicotine content as compared with the other varieties. The nicotine content

in 1977 ranged from 3.57 to 4.61.

Coker 347 has a higher proportion of the alkaloid in the form of

nornicotine than the other varieties. All of the varieties were in a range

of 8.41 to 11.31 percent sugar and the sugars in 1977 were on an average lower

when compared to the 1976 crop.

The ratio (reducing sugar/nicotine) was calculated as a measure of the

relationship of the carbohydrates to the alkaloid fraction. To be of value,

the constituents included in the ratio must be within the acceptable range.

A higher ratio tends to indicate mildness and smoothness while a very low

ratio may be indicative of a harsh irritating smoke. If the ratio is too

high, it might indicate that the tobacco is too mild to be acceptable to the

smoker. There was a range fram 1.98 for NC 3150 to 3.14 for McNair 944.

Information on disease resistance is presented in Table 5. Data were

collected on Black Shank, Bacterial Wilt, Root Knot and MOsaic. A relative

rating of the level of resistance to each disease is given for each variety

based on this and other disease tests. The disease tests were fairly critical

at all locations. Much progress appears to have been made in developing

disease resistant varieties released in the last few years. There are several

varieties carrying a high level of resistance to Black Shank, Bacterial Wilt

and Root Knot. Several other varieties carry a moderate to high level of

resistance to Bacterial Wilt. The choice of varieties carrying Bacterial Wilt

resistance is somewhat higher than in recent years. One new variety carries

(15)

Advanced Breeding Lines

Data on advanced breeding lines are shown in Table 4, however, since

these lines are in early stages of testing, the data will not be discussed in

detail at this time.

Since most of the breeding lines have only been in the Official Variety

Test for one year, regional testing was not available. The lines are rated

for resistance with an index or level of resistance shown. For Black Shank and

Bacterial Wilt the percent diseased plants is shown. Root Knot and Mosaic

resistances are recorded as resistant or segregating.

It has been difficult to obtain varieties or breeding lines with multiple

resistance to all diseases, good physical and chemical characteristics and

acceptable smoke ratings. Under the Acreage-Poundage Program, some pressure

has been eliminated for the plant breeder to continue to develop each year

higher and higher yielding lines. This situation has enabled the plant breeder

to direct more attention to selection criteria for disease resistance.

Many of the entries carry resistance to Root Knot nematode species,

Meloidogyne incognita, which is the most prevalent species of nematode in

North Carolina soils. There are other species of Root Knot nematodes as well

as meadow and stunt nematodes to which these lines may be susceptible.

Regional Farm Tests

A summary of the results from the Regional Farm Tests is presented in

Table 11. Yields ranged from 2322 for NC 2326 to 2669 for NC 64. Value per

acre ranged from $3346 for NC 2326 to $3758 for NC 64. NC 2326 had the highest

dollars per hundred pounds of entries in this test with a value of $143.99.

This was $24.33 per hundredweight more than the highest entry in 1976.

The tobacco from each of the locations was displayed on a warehouse floor

(16)

body and texture by leaf and research personnel of each of the nine

partici-pating tobacco companies. The results of this quality appraisal are shown

in Table 12. The ratings varied from company to company but tended to follow

the same general pattern.

Table 13 shows percent tobacco usable by at least one company for

individual North Carolina farms and a mean for all farms and varieties. The

high numbers indicate the the majority of the new lines could be used by at

least one buying company.

In Table 14, an index of the amount graded is shown by grower for each

variety. If all eight companies could grade all of a variety into their

grades, then it received an index of 9. However, since companies have different

requirements, all would not tend to grade each lot of new line tobacco. In

the overall average for all companies, the varieties, NC 2326 and NC 95,

received the highest ratings.

The farmers were asked to rate the varieties for grower desirability with

their highest preference shown as number one, the lower the number the more desirable the variety. These data are shown in Table 16. The rating indicated

that the growers preferred Speight G-52 and NC 95 over other varieties.

Both physical and chemical information should be considered along with

yield and value data relative to a variety or line. Also the handling

characteristics are important. A thorough evaluation of breeding material is

important if quality is to be maintained and improved.

The various indices are not conclusive but show trends in preferences

which are indicative of the acceptability and desirability of these tobaccos by

manufacturers and growers. All information should be studied relative to varietal

(17)

Table 13 presents data from the two breeding lines in the Regional Small

Plot Tests that were common in the Regional Farm Test. It shows the percent

cured leaf usable by tobacco companies across six locations and the rating for

variety potential. Speight G-52 showed the largest percent usable by the

participating companies. In the company ratings for variety potential, the

higher number indicates the highest rating. Speight G-52 and NC 64 received

the same rating.

Chemical growth regulators were used on the Regional Farm Test in 1977.
