Estimation of genetic variability for certain characters in a random mating population of maize


, : Estimation of genetic variability for certain characters in a random mating population of maize. Journal of Maharashtra Agricultural Universities 17(1): 23-25

One hundred an sixty biparental progenies developed using North Carolina Design I in an early, white, semiflint population of maize were evaluated at two locations to estimate the genetic variance andd predicted response to selection for height and maturity traits. The dominance variance was found to be more important for the traits days to mid silk, plant height whereas additive genetic variance was for grain moisture and ear height. Additive x location and dominance x location interaction components were found to be significant for grain moisture and ear height. An expected genetic gain from one cycle of full-sib family selection was about three times more than that of mass selection.
