Assessment of genetic variability, heritability and genetic advance in pea (Pisum sativum)

Abstract

Studies on genetic variability, heritability and genetic advance were carried out among twenty genotypes of pea for character to identify genotypes to be used in breeding programme. The result showed high phenotypic and genotypic co-efficient of variation for traits like plant height (GCV = 27.62; PCV = 27.65). High heritability values were obtained all the characters. In high heritability coupled with high genetic advance as per cent of mean was observed plant height (56.84%), number of pods per plant (43.73 %), length of first fruiting node (43.44 %), pod yield per plant (38.62 %), pod yield q/ha (38.61 %), days to 50% flowering (33.25 %) and number of seeds per pod (24.28 %), This indicated substantial of additive genetic variance in expression of these characters and can be useful in hybridization and selection for higher pod yield.
