【 摘 要 】
Groundnut is a highly self-pollinated crop and due to the uniformity of the traits imposed by the peanut growers, it is losingits genetic base. Hence, there arises a concern for creating more genetic variability in the population. With this informationin background, the present study was carried out to examine the variability of prominent yield and yield attributing traits inthis unpredictable legume crop. This will provide insight into the expression of traits and the influence of environment onthose traits. High GCV, PCV values were recorded for the number of pods per plant, 100 pod weight, 100 kernel weight,shelling percent and number of mature kernels in the present study. This indicates the presence of ample variability for thesetraits. Hence these traits can be opted for selection as they contribute more towards variability with least influence ofenvironment over it. Most of the traits recorded high heritability and high GAM, which is a positive sign for least influenceof environment on population and presence of additive gene action.
