Abstract

The range, phenotypic and genotypic coefficients of variation, heritability and genetic advance were estimated under normal and rainfed conditions for eight quantitative traits in sixty progenies derived through seltlng and intermatlng in durum wheat cross Shwa ‘s’ X V44. The biparental mating is able to maintain variability for selection of improved genotypes. High heritability estimates coupled with high genetic advance were observed for number of grains per ear, grain yield and biological yield per plant under both the environments. Medium to low heritability estimates were recorded for days to earlng, plant-height, tiller number per plant, 1000 grain weight, harvest-Index under both the environments. Selection based on number of grains per ear and biological yield may be effective for improvement in durum grain yield under normal or ralnfed conditions.
