Genetics of Some Quantitative Traits in Six-Rowed Barley (Hordeum vulgare L.) over Three Environments

Abstract

Genetic component of variances were estimated for ten characters in a 10 x 10 dialiel fashion over three
environments. The findings reveled that both additive (D) and non-additive (HI & H2) components of variation
were important for ali the characters. However, the relative magnitude of dominance component was higher than
additive component Le. prevalence of non-additive gane effects and over dominance suggested that on or the other
form of biparental and/or recurrent selection procedures and dialiel selective mating might give fruitful results for
improving the grain yield in six rowed barley.
