“…The genotype AK 265 was found to be suitable for favourable situations with predictable performance as it posses high oil content with below average responsiveness (Regression coefficient bi>1) and non-significant deviation from regression line (S 2 di; p>0.05; Table 2). Results of similar nature were reported by Upadhaya et al (2012) and Kirmani et al (2013). Different sets of genes may operate in different locations and in different seasons.…”

Groundnut (Arachis hypogaea L.) is an important oilseed crop commercially cultivated in India. The adaptability and stability of some groundnut genotypes was assessed during 2011-2012 in different growing seasons (kharif, rabi and summer) with different sowing dates with combination of fertilizer levels at Oilseeds Research Unit at the Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, India. The pod yield and seed oil content were recorded. Pooled analysis of variance of pod yield and seed oil content over diverse environments revealed the presence of genotype x environment interaction and significant differences among the genotypes and environments (p<0.05). The partitioning of G × E interaction indicated that the linear component was significant (p<0.05) against pooled deviation for both traits. The non-linear component (pooled deviation) was also significant (p<0.050 when tested against the pooled error revealing presence of non-linear responses of the genotypes to the changing environments. The genotype AK 320 exhibited specific adaptability for favorable environments and the genotype AK 342 showed adaptability for unfavorable environments with respect to pod yield. However, both varieties were not stable across environments for the seed oil content though their seed oil content improved proportionate to the improving environment. The genotype AK 327 showed the highest general adaptability over diverse environments in respect of both pod yield and seed oil content. In general, the genotypes that showed high level of stability were not high yielders and the high yielders were found to be unstable in pod yield and seed oil content.

“…Peanuts with high protein and low oil but with improved oil quality and rich in minerals will be the most preferred confectionery products. Efforts at ICRISAT and elsewhere have succeeded in identifying or developing peanut cultivars with variation in seed size, protein, oil content, and oil quality (Upadhyaya et al, 2012), but no concerted efforts were made to identify sources of the essential minerals such as Fe and Zn. The genebank at ICRISAT in Patancheru, India, maintains a large global collection (15,445 accessions) of peanut germplasm.…”

“…The genotypes ICGV 02038, TG LPS 3, Faizpur 1-5, and ICGV 01276 recorded high protein content of 26-28% among the GSP. Significant effect of environment and genotype × environment interactions for protein content in groundnut (Dwivedi et al, 1993, Upadhyaya et al, 2012 indicated the need to test the performance of the genotypes in different growing environments before using in breeding programs. One genotype in the GSP, SunOleic 95R, an introduction from the USA recorded high oleic acid content of 74%, indicating a strong need to breed high oleic groundnut lines.…”

A set of 340 diverse groundnut genotypes included in Genomic Selection Panel (GSP) was used to evaluate genetic parameters and trait associations for resistance to rust and late leaf spot (LLS) along with yield and nutritional quality traits. The findings revealed high genetic variability coupled with high heritability and genetic advance as percent of mean (GAM) for resistance to both the diseases and yield traits, whereas low variability for nutritional quality traits with high heritability and low GAM. Disease severity scores for rust and LLS at 90 days after sowing (DAS) were negatively associated with yield, indicating pod yield penalty, thus deploying host-resistance for rust and LLS is a good strategy to plug the pod yield losses and reduce the input cost. It is possible to simultaneously improve the number of pods per plant and hundred kernel mass that contribute to pod yield as no trade-offs were detected between them. The association of oil and protein content with pod yield showed no tradeoffs, suggesting the possibility of simultaneous improvement of pod yield either with high oil or protein content. In breeding programs that target development of groundnut varieties to meet two distinct end-uses, oil milling, and food and confectionery, selection for either high oil (for oil purpose) or high protein and low oil (food/confections) will be efficient, as an inverse association between oil and protein content was observed. The use of disease score at 90 DAS for rust and LLS is effective and optimizes resources to make selection decisions in breeding as positive association among disease severity scores at different periods (75, 90 and 105 DAS) was observed.
