Genetics of Yield and its Components in Barley (Hordeum vulgare L.)

Abstract

Estimation of gene effects based on analysis of generation means were obtained for grain yield per plant, and its three components namely number of ears per plant, number of grains per year and 1OO-grain weight in three crosses of barley (Hordeum vulgare L.). The contribution of dominance gene effects (h) were found more important than additive gene effects (d) in the inheritance of these traits. Among the epistatic effects, all were found to be of considerable importance in all the characters.
