Abstract
A comparison of heritability estimates from regression and intra-class correlation analyses in full-sib and half-sib families showed that heritability estimates from regression analysis are lower than intra-class correlation estimates in both types of families. The heritability estimates from half-sib families are higher than from full-sibs for all the traits except number of leaves per plant and 100-seed weight. A comparison of heritability estimates from offspring- parents, bOP1, bOP2 and bOMP showed that heritability estimates from regression of offspring-mid parent are higher than offspring-one parents. Further, leaf length showed the lowest heritability in regression analysis. The overall results showed that plant height, 100-seed weight and number of leaves per plant showed higher heritability.
