Study on genetic variability, heritability, genetic advance and genetic divergence in field pea (Pisum sativum L.)

Thirty six advanced lines including four checks and twelve cultivars of pea were studied for genetic variability, heritability, genetic advance and genetic divergence for ten characters. The heritability estimates were found to be higher for all characters except no. of primary branches per plant. High genetic advance coupled with high heritability estimate were predicted for plant height, no. of pods per plant, biological yield per plant, harvest index and grain yield per plant indicating least influence by the environment. On the basis of D2 analysis all genotypes are grouped into five clusters which indicate genetic variation present among genotypes studied.
