Abstract: Twenty four germplasm line and eight cultivar of groundnut were planted in three replication of RBD design with two different dates at research farm of COA Gwalior and KVK Ashoknagar each in kharif 2018. The pooled analysis of variance was significant for all characters, plant height (cm), days to 50% flowering, days to maturity, number of primary branches, number of secondary branches, number of pods per plant, pod yield per plant (g), kernel yield per plant (g), shelling (%), sound matured kernel (%), 100 pod weight (g), 100 kernel weight (g), biological yield per plant (g) and harvest index (%).High heritability estimates were observed for number of 100 pod weight (94.13%), moderate heritability estimates were expressed by kernel yield per plant (66.67%) and sound mature kernels (42.74%) exhibited low estimates of heritability. High value of genetic advance as percent of mean was observed for 100 pod weight (33.17%) while moderate value of genetic advance was observed for biological yield per plant (12.83%). The highest GCV and PCV was observed for 100 pod weight (767.91%) and (815.77%).
