“…The extent of genetic variability and the degree of its heritability available in the germplasm determines the effective superior genotype (Johnson et al, 1955).The present investigation had shown that the phenotypic coefficient of variation (PCV) value for all thirteen biometrical traits was higher than that of genotypic coefficient of variation (GCV) suggesting the role of environment on the phenotype of the crop and presented in Table 1. Similar results was also reported by Mubai et al (2019) and Sab et al (2018). In this study, the higher estimates of PCV and GCV was expressed for plant height, primary branches per plant, Clustering is also used to summarize information on relationships between objects by grouping similar units so that the relationship may be easily understood and communicated.…”

Background: The present investigation was conducted at Agricultural College and Research Institute, Killikulam, Tamil Nadu during the year 2022-2023 involving 220 groundnut genotypes along with a resistant and susceptible check towards validation of phenotypic extremities on yield and its contributing traits besides screening against late leaf spot resistance. Methods: The data collected from two hundred and twenty germplasm along with check varieties for thirteen quantitative traits. The collected data were subjected to statistical analysis (Mahalanobis, 1936) besides interpreted by various genetic tools such as PCV, GCV, heritability and GAM. Further, ten plants were selected at random from each genotype and observation on late leaf spot disease was recorded based on modified 9 point scale. Result: Molecular analysis for LLS resistance among the groundnut germplasm had shown the concurrent superiority in terms of yield and resistance to late leaf spot disease among the genotypesICG 15233, ICG 8760, ICG 76, ICG 111, ICG 297, ICG 405, ICG 238, ICG 4598, ICG 5051, ICG 6057, ICG 8253, ICG 8285, ICG 10701 and ICG 15234. Hence, these genotypes can be exploited to develop a disease resistance and high yielding groundnut culture.

“…Higher heritability and genetic advance as a per cent of mean indicating greater nonadditive gene action was observed for all traits except kernel width and oil content wherein the lower h 2 , GCV and GAM were reported suggesting more of additive gene action. The results were akin to the reports given bySab et al (2018) andPatil et al (2014).…”

“…The crop's productivity can be increased by locating genotypes that make better utilization of the limited water resources (Arunkumar et al, 2017). Specific leaf area (SLA) and SPAD chlorophyll meter reading (SCMR) are associated with WUE in groundnut as surrogate traits to select the genotypes with high WUE (Sab et al, 2018) which could ultimately lead to the evolution of better genotypes adapted to drought conditions. Success of plant breeding programme depends largely on the choice of appropriate parents.…”

To establish the degree of genetic diversity for 14 quantitative parameters, 36 groundnut genotypes were investigated using the Mahalanobis D 2 Statistics. Tocher's method separated the entire genetic resource set into nine distinct, non-overlapping clusters demonstrating the presence of significant amount of genetic diversity. Cluster I had the maximum number of accessions (15), followed by cluster IV with 7 accessions, cluster VI with 5 genotypes, cluster V with 3 genotypes and cluster VII with 2 genotypes. The clusters II, III, VIII and IX were monogenotypic. The intercluster distance was maximum between the clusters VI and IX. Shelling percent contributed maximum to the genetic divergence followed by pod yield plant -1 . Hence due emphasis should be given to these traits as improvement of these characters would result in increase in pod yield plant -1 .
