Author(s): Harkesh Saini and MM Sharma
Abstract: An experiment was one hundred forty-nine groundnuts (Recombinant inbred Lines) RILs were tested. Highly significant variations were observed among the RILs for all the characters studied. The highest genetic coefficient of variation was observed for kernel yield per plant, harvest index, pod yield per plant, number of pods per plant, biological yield per plant and 100-kernel weight. The highest heritability was observed in 100-kernel weight (g) followed by pod yield per plant (g), shelling percentage, kernel yield per plant (g), biological yield per plant (g), harvest indexand palmitic acid while high values of genetic advance as per cent of mean were obtained in all the characters except shelling percentage and palmitic acid. The kernel yield per plant showed the highly significant and positive association with number of kernels per pod, number of pods per plant, pod yield per plant (g), 100-kernel weight (g), shelling percentage, biological yield per plant (g), harvest index, stearic acid. The kernel yield per plant had high positive direct effect on pod yield per plant followed by harvest index, oleic acid, linoleic acid, number pods per plant, oil content, protein content, palmitic acid, number of branches per plant, days to 50% flowering, biological yield per plant and 100-kernel weight. Therefore, kernel yield per plant, number of kernels per pod, pod yield per plant (g), number pods per plant, 100-kernel weight (g), shelling percentage, biological yield per plant (g), stearic acid, harvest index, oleic acid and linoleic acid were identified to be the important characters which could be used in selection for yield.
