Abstract:
The current study examined the nature of genetic variability, heritability, and genetic advance in 30 groundnut genotypes. Table 1. shows the results of the analysis of variance for each of the ten characters. For all of the traits studied, the results revealed highly significant differences between genotypes. This suggested that there was enough variance in all of the traits to allow for effective selection in the material under examination. GCV and PCV estimates were high for kernel yield per plant, pod yield per plant, number of pods per plant, and plant height. Most of the characters studied had higher heritability estimates, with the exception of oil content, number of branches per plant, and oil content. However, for characteristics such as kernel yield per plant, pod yield per plant, number of pods per plant, plant height, and shelling %, considerable genetic advance as a percentage of mean was seen. While the number of branches per plant, 100 kernel weight, days to 50% flowering, days to maturity, and oil content were showed moderate to low genetic advance. Presented in the Table No. 2.
