4.2.3 Nutritional quality traits

Genotypes with higher nutritional value and quality in groundnut are in great demand, therefore, improving nutritional quality is now one of focused breeding objective of groundnut improvement. All the genotypes were evaluated for oil and protein content along with four major fatty acids through near infrared reflectance spectroscopy (NIRS). The mean, range and genetic parameters for nutritional quality traits are presented in Table 4.19. The range of performance of genotypes for all the nutritional quality traits was high but GCV and PCV were low for all the quality traits coupled with moderate to high heritability and low GAM at the individual as well as across the environments.

Oil content (%)

Narrow genetic variability in GSP observed for oil content with low GCV and PCV along with moderate to high heritability and low GAM across the environments. Oil content was varied from 45.0 to 64.2% at Aliyarnagar, from 46.1 to 64.9% at Jalgaon, from 38.2 to 59.9% at ICRISAT rainy 2015, from 42.0 to 60.6% at ICRISAT post-rainy 2015-16 and the average over environments was varied from 44.6 to 59.2%. The average of environments over genotypes was 53.5% at Aliyarnagar, 53.7% at Jalgaon, 48.5% and 49.1% at ICRISAT rainy and post-rainy seasons, respectively (Table 4.19). Very low GCV (2.51%) and PCV (3.38%) with moderate heritability (54.93%) and low GAM (3.83%) were reported for oil content at Aliyarnagar.

The genotypes ICG 14482 (64.2%) followed by ICG 12625 (63.5%) and ICGV 99085 (62.7%) were the best genotypes had higher oil content compared to other genotypes at Aliyarnagar whereas genotypes ICGV 06420 (64.9%) followed by ICGV 99085 (62.5%) and ICGV 05155 (62.0%) recorded higher oil content at Jalgaon. Genotypes ICG 15419 (59.9%) followed by ICG 2381 (29.3%) and ICG 5221 (58.8%) reported higher oil content compared to other at ICRISAT during rainy season 2015 whereas ICG 2381 (60.6%) followed by ICGV 97045 (57.9%) and ICG 14475 (56.4%) were the best genotypes for oil content at ICRISAT during post-rainy season 2015-16. Pooled analysis of genotypes for oil content across the environments also revealed low values of GCV and PCV (2.39 & 2.67%) with high heritability (79.78%) and low GAM (4.39%). The average performance of genotypes across the environments revealed that genotypes ICG 15419 (59.18%) followed by ICG 2381 (58.97%), ICG 5221 (58.61%) and ICG 14482 (58.50%) reported high oil content across the environments (Table 4.20).

Protein content (%)

Narrow genetic variation in GSP was observed for protein content with low GCV, PCV coupled with moderate heritability and low GAM under different environments. Protein content in GSP varied from 13.5 to 28.4% at Aliyarnagar, from 13.2 to 27.8% at Jalgaon, from 19.2 to 29.8% at ICRISAT rainy 2015 and from 19.6 to 34.6% at ICRISAT post-rainy 2015-16. The average of environment over the genotypes was 20.2% at Aliyarnagar, 19.6% at Jalgaon, 24.1 and 26.7% at ICRISAT rainy and post-rainy seasons, respectively (Table 4.19). Low GCV (4.20%) and PCV (6.60%) with moderate heritability (40.55%) and low GAM (5.51%) were reported for protein content at Aliyarnagar. The similar trend of low GCV (2.65 & 3.08%) and PCV (4.37 & 4.85%) coupled with moderate heritability (36.84 & 40.33%) and low GAM (3.32 & 4.03%) was observed at ICRISAT rainy 2015 and ICRISAT post-rainy 2015-16, respectively whereas low GCV (3.38%) and PCV (6.27%) coupled with low heritability (29.04%) and low GAM (3.75%) was reported for protein content at Jalgaon. Protein content in different genotypes was observed high during the post-rainy

108

season compared to rainy season across the environments. Genotypes ICGV 02038 (28.4%) followed by DTG LPS 3 (27.2%) and Faizpur 1-5 (26.7%) reported higher protein content at Aliyarnagar whereas ICGV 05198 (27.8%), 00321 and 02038 (25.1%) were the best genotypes for protein content at Jalgaon. ICG 14985 (29.8%) followed by ICGV 00362 (28.4%) and ICGV 05176 (28.0%) recorded higher protein content at ICRISAT during rainy 2015 whereas Faizpur 1-5 followed by ICG 2857 (34.1%) and ICGV 02038 (33.3%) reported higher protein content at ICRISAT during post-rainy season 2015-16. Pooled analysis of genotypes for protein content across the environments also revealed a similar trend of low GCV and PCV (2.98 & 3.71%) with high heritability (64.42%) and low GAM (4.93%). Pooled performance of genotypes showed that genotypes Faizpur 1-5 (27.7%) followed by ICGV 02038 (27.4%), ICGV 00321 (26.7%) and ICG 9507 (26.4%) reported higher protein content across the environments (Table 4.20).

Oleic acid (%)

Narrow genetic variation in GSP was observed for oleic acid content with low GCV, PCV coupled with moderate to high heritability and low GAM under different environments. Oleic acid in GSP varied from 29.4 to 74.4% at Aliyarnagar, from 21.3 to 80.5% at Jalgaon, from 31.4 to 76.0% at ICRISAT rainy 2015, from 30.3 to 76.1% at ICRISAT post-rainy 2015-16 and the average over environments from 31.2 to 78.8%. The average of environments over genotypes was 42.1% Aliyarnagar, 38.9% at Jalgaon, 42.9 and 43.9% at ICRISAT rainy and post-rainy seasons, respectively (Table 4.19). The wider range of oleic acid in GSP is due to a high oleic genotype SunOleic 95R which recorded >74% oleic acid across the environments. The range of oleic acid in GSP without SunOleic 95R became narrow from 29.4 to 60.3% at Aliyarnagar, from 21.3 to 56.9% at Jalgaon, from 31.4 to 62.4% at ICRISAT rainy 2015, from 30.3 to 58.5% at ICRISAT post-rainy 2015-16 and the average over environments from 31.2 to 57.4% indicating narrow genetic variability for this trait. Low GCV (5.80, 6.83, 6.02 & 4.91%) and PCV (7.19, 8.19, 6.66 & 6.41%) with high heritability (65.11, 69.51, 81.61 & 58.61%) and low GAM (9.64, 11.73, 11.19 & 7.74%) were reported for oleic acid content at Aliyarnagar, Jalgaon,

The average of environments over genotypes was 11.7% at Aliyarnagar, 11.9 at Jalgaon, 11.7 and 12.5 at ICRISAT rainy and post-rainy seasons, respectively (Table 4.19). Very low GCV (4.07, 4.43, 4.16 & 3.66%) and PCV (4.91, 5.24, 4.73 & 4.45%) with high heritability (68.66, 71.42, 77.35 & 67.82%) and low GAM (6.94, 7.71, 7.53 & 6.21%) was observed for palmitic acid content at Aliyarnagar, Jalgaon, ICRISAT rainy and post-rainy seasons, respectively.

112

at Aliyarnagar, 2.10% at Jalgaon, 1.65 and 2.33% at ICRISAT rainy and post- rainy seasons, respectively (Table 4.19). Low GCV (9.11 & 7.97%) and moderate PCV (11.89 & 10.69%) with moderate heritability (58.61 & 55.53%) and GAM (14.36 & 12.23%) was reported for stearic acid content at Aliyarnagar and ICRISAT post-rainy 2015-16, respectively whereas moderate GCV (10.48%) and PCV (14.00%) coupled with moderate heritability (56.10%) and GAM (16.18%) was reported at Jalgaon. High GCV (28.24%) and PCV (30.98%) coupled with high heritability (83.14%) and high GAM (53.05%) were reported for stearic acid content at ICRISAT rainy 2015. A similar trend of high GCV and PCV (31.42 & 33.51%) with high heritability (87.91%) and GAM (60.69%) was reported in pooled analysis. The genotypes ICG 4955 (0.7, 0.3, 0.2 and 0.8%) reported lowest stearic acid at Aliyarnagar, Jalgaon, ICRISAT rainy and post-rainy seasons, respectively.

Oleic acid / Linoleic acid (O/L Ratio)

There was moderate variability reported for O/L ratio in GSP with moderate GCV and PCV with high heritability and GAM. It varied from 0.58 to 14.03 at Aliyarnagar, from 0.37 to 15.71 at Jalgaon, from 0.68 to 12.76 at ICRISAT rainy 2015, from 0.62 to 16.53 at ICRISAT during the post-rainy season and the average over environments was from 0.66 to 14.09. The average of environments over genotypes for linoleic acid was 1.13 at Aliyarnagar, 0.99 at Jalgaon, 1.26 and 1.35 at ICRISAT rainy and post-rainy seasons, respectively (Table 4.19). The wider range of O/L ratio in GSP was due to SunOleic 95R as it was recorded highest O/L ratio at Aliyarnagar (14.13), Jalgaon (15.71), ICRISAT rainy (12.76) and post-rainy (16.53) (Table 4.21).
