PERFORMANCE OF SMALL GRAIN VARIETIES IN NORTH CAROLINA
INTRODUCTION
Across the state of North Carolina during the fall of 1990,
growers planted 32,000 acres of barley, 85,000 acres of oats, and
550,000 acres of wheat.
experienced in the fall.
Favorable planting conditions were
with the large number of commercially available and
prospective varieties of barley, oats, and wheat , i t becomes
difficult for growers to select a superior variety suited for their
particular area of the state. To make this decision, the grower
needs up-to-date, unbiased, reliable information. The Official
Variety Testing Program, through this report, seeks to provide that
type of information.
Information on varietal performance is presented from seven
test locations in the state.' Also included are mUltiple-year
performance data on a selected number of varieties.
2
COMPARING VARIETIES
Performance of a variety cannot be determined with absolute
precision. Even though the tests are conducted in a uniform
manner, as much as possible, uncontrollable variability exists
among experimental plots due to soil, fertility, moisture, insects,
diseases, and other sources of variation. Because this variability
exists, statistics are used as a tool to determine differences
among varieties. The size of difference among varieties which may
have been due to chance variation is listed in each table as the
B.L.S.D. (least significant difference). Those varieties which do
not differ by more than the B.L.S.D. are not statistically
different.
varietal performance may appear inconsistent among locations
within an area or among years at a particular location, thus i t is
Lmport.ant; for the reader to examine results from more than one
location within an area or more than one year at a particular
location, to obtain a more accurate picture of relative varietal
performance. An effort has been made to facilitate comparisons
among locations and years in this report.
The varieties which do not yield significantly less than the
highest yielding variety are denoted by an asterisk (*) next to
their yields. The relative performance of a variety across
locations within an area can be easily evaluated by going across
the table; those varieties which are most frequently marked by an
asterisk would be highly desirable. other agronomic
character-istics may be as equally important as yield. All available data
3
are found in Tables 1, 2 , and 3 for barley, oats, and wheat,
respectively.
It is suggested that the grower plant a small number of acres
in a new variety when first determining if i t is adapted to his

EXPERIMENTAL PROCEDURE
The state is divided into physiographic regions and tests were
located in the Piedmont and Coastal Plain (Figure 1). Tests were
located on private farms and on research stations.2
Entries: Commercial varieties and experimental lines developed by
public and private agencies are included in these tests. Any
individual or firm may make application for having entries included
by writing Official variety Testing Program, Department of Crop
Science, North Carolina State University, Raleigh, N.C. 27695-8604.
A fee is charged on an entry basis for all private entries.
Entries of specific interest to North Carolina seedsmen may have
been included on a no-fee basis. A total of 9, 10, and 32
commercial varieties and experimental lines of barley, oats, and
wheat, respectively, were evaluated in the 1990-91 season.
Field Plot Design: A randomized, complete block design with four,
five, or six replications was used at each location.3 Each plot
consisted of eight rows, 7.5 inches apart, 18 or 19 feet long with
2.5 feet between each plot.
Crop Management: Cultural practices, such as seed bed preparation,
date of planting, fertilization and topdressing were in accord with
good farming practices and were uniform for all entries at a given
location (Table 4). Prior to planting each test, soil samples were

SEASONAL CONDITIONS
The 1990-91 small grain growing season was characterized by
normal rainfall in the fall which allowed pla~ting to be on time
(Table 4). Above-normal temperatures from January through May were
experienced at all locations. The warm weather in May promoted
rapid dry-down; consequently all small grains were ready to harvest
at least one week earlier than average.

Conditions were ideal for many diseases. Powdery mildew,
crown rust, leaf rust, and Septoria leaf blotch were evident to the
point where valid ratings could be made. Barley yellow dwarf virus
14
beetle was also evident at several locations although most
locations did not require an application of insecticide; the Rowan
location was sprayed. Glume blotch occurred at most locations in
the Coastal Plain and in the Piedmont
DATA
Yield is reported in bushels per acre by location, area and
across all locations within the state as well as across years by
location and area. Test weights in pounds per bushel were reported
averaged across the state. Lodging was reported in percentage
averaged across all locations within the state; the lodging data
are for lodging prior to harvest. All plots were adjusted to 13%
moisture.
Disease ratings are reported in the state-wide averages
although they may have only been taken at one or more locations.
Yield data were analyzed. The average yield of each test was
indicated on the bottom of the tables. The B.L.S.D. K-50 is
equivalent to the Fisher's L.S.D. at the 10% level. The standard
error of the mean (s.e.) is an indicator of the precision of that
test; the smaller the s.e., the more precise the estimate of yield
is for any particular variety. The s.e. of the mean is equal to
the standard deviation divided by the square root of N; N is
normally the number of replications in the trials.
In calculating averages, equal weight was given to each
location, therefore, two and three-year averages may not appear to
equal the average between years when the number of locations varies
15
RESULTS AND DISCUSSION
Barley
There are no data for Wysor barley this year due to a seed
mixture prior to receipt by the Official Variety Testing Program
and lack of knowledge of the mix-up until after the barley had
headed.
Yields across the state averaged 58 bushels per acre (Table
6). There were no significant yield differences in the statewide
average due to a large variety by location interaction. Test
weights were low and lodging was high. Date 50% headed was taken
at the Granville county location and should indicate relative
maturity. Powdery mi Ldew was evident at the Columbus county
location and significant differences could be detected.
Two and three-year data are shown in Tables 7 and 8. These
data more accurately reflect relative performance among the
varieties. Growers are cautioned to examine more than one year of
data when selecting varieties.
Individual location data, area data, and mUltiple year data
are shown in Tables 9, 10, 11, and 12. Yields were extremely low
at Columbus county; the barley began lodging by the first of May
(Table 10).
OATS
Oat yields were excellent at most locations across the state
reSUlting in an overall average of 95 bushels per acre (Table 13).
No significant differences were detected in the statewide analysis
due to a large location by variety interaction, i. e. varieties
performed different relative to each other at the various
16
to be a problem with oats although the combine was able to pick up
most of the grain. Date 50% headed was taken at Granville county.
Septoria leaf blotch, crown rust, and powdery mildew ratings were
taken at various locations in the Coastal Plain; the most severe
disease incidence occurred at Columbus county. The variety, 833,
from Arkansas County Seed Company was not included in the statewide
average because i t was only tested in the Coastal Plain locations.
It had disease ratings of R, R, and MR for Septoria leaf blotch,
crown rust and powdery mildew, respectively.
Two and three-year data across the state are reported in
Tables 14 and 15. Individual location data, area data, and
mUltiple year data are shown in Tables 16, 17, 18, and 19. Low
yields were evident at Columbus county due to disease as mentioned
previously and early lodging (Table 17).
WHEAT
Yield and test weights were good to fair across the state
(Table 20). The 1000 kernel weight is another more accurate
measure of milling quality also shown in Table 20. Lodging was
above average with some locations, e.g. Columbus county,
experiencing 100% lodging in some plots. Date 50% headed was taken
at Granville county. Powdery mildew and leaf rust ratings were
taken at several locations in the Coastal Plain with Columbus
county experiencing the heaviest disease pressure.
The following entries are not in the statewide average since
they were only tested in the Coastal Plain: AgraTech 91W, AgraTech
ATW 270, NC 87-71, NC 87-75, NK Coker 9227, and NK Coker 9766.
17
and S, respectively. Leaf rust ratings were R, R, MR, MR, R, and
R, respectively.
Two and three-year averages are shown in Tables 21 and 22.
