Abstract
The present experiment was conducted at School of Agriculture, ITM University, Gwalior (M.P) during Kharif season of 2022 the design of experiment followed after Randomized Block Design With three replications. The present investigation was conducted to examine the 12 Groundnut genotypes to study the genetic variability, correlation, and path coefficient analysis. Analysis of variance showed highly significant differences among all genotypes for 16 quantitative characters studied. Maximum GCV and PCV were recorded for number of branches plant-1 and plant height. High heritability coupled with genetic advance as percent of mean recorded for number of branches plant-1, plant height, kernel yield plant-1, days to 50% flowering and shelling percentage. Correlation coefficient analysis determined that kernel yield plant- 1exhibited significant and positive correlation both at genotypic and phenotypic level with number of pods plant-1, shelling percentage, harvest index and pod yield plant-1. Path coefficient analysis revealed that days to 50% flowering, days to maturity, plant height, shelling percentage, biological yield, harvest index, number of seeds pod-1, oil content, sound mature kernel percent, pod yield plant-1showed positive direct effect on kernel yield plant-1. These character can be directly selected for further breeding program.
