Characterization of pumpkin (Cucurbita moschata Duch. Ex. Poir.) germplasm through genetic variability, heritability and genetic advance
Abstract
Twenty five pumpkin germplasm from the north eastern region were evaluated for twenty traits for the genetic variability, heritability and genetic advance. The results revealed that analysis of variance showed that there was a highly significant variation for all of the considered characters. In the present investigation, PCV was recorded higher than the GCV for all the characters indicating the considerable modifying effect of environment in the expression of all characters studied. The highest PCV and GCV was observed for vitamin A (PCV=86.27%, GCV=86.23%) followed by cavity length (PCV=35.52%, GCV=34.24%) and 100 seed weight (PCV=30.04%, GCV=29.37%). The maximum estimate of heritability (in the broad sense) recorded for vitamin A (100%) followed by cavity length (98%), carbohydrates (98%), 100 seed weight (96%) and fruit yield per plant (95%). The highest genetic advance as per cent of mean was observed for the characters vitamin A followed by cavity length, 100 seed weight and fruit yield per plant. Therefore, keeping the above point of view the genotypes could be select for the further breeding programme.
