Abstract

The present study was aimed to assess genetic variability for yield and yield component traits among 100 released Indian groundnut varieties and were evaluated during post rainy season (January-June) 2023-24 at the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT) Patancheru, Hyderabad. The analysis of variance revealed significant differences among the varieties for all the traits suggesting that the varieties had very good diversity and will provide valuable insights. The genetic parameters revealed very good amount of genetic variability for exploitation. High genotypic coefficient of variation (GCV) and phenotypic coefficient of variation (PCV) were observed for the traits, pod yield (kg/ha), kernel yield (kg/ha), oleic acid (%) and linoleic acid (%) suggesting substantial variability that can be utilized in breeding programs. The traits, oleic acid (%) and linoleic acid (%) showed high heritability and high genetic advance as percentage of mean, implying that the heritability is likely due to additive gene effects and simple selection is effective for the improvement of these traits.
