ENTRIES PERFORMANCE OF BREAD WHEAT AND ESTIMATION OF PHENOTYPIC AND GENETIC VARIANCES AND GENEIC CORRELATION

Abstract

Twenty bread wheat of ICARDA in addition to the local variety, Abou-Garib 3 were evaluated in Nienvah governorate, Iraq for two locations, , Al-Rashidia and Rabeeha,15 and 120 km from Mosul center . The characters studied were : plant height, number of spikelets/spike, number of grains/spike, number of spikes/m2, grain yield, biological yield, harvest index,1000-grain weight and protein percentage. Values of phenotypic and genetic variances were significant for all characters. For both locations, genetic correlation was positive and significant between grain yield and harvest index, broad sense heritability estimates were high for protein percentage and low for plant higher, grain yield, biological yield, harvest index and 1000- grain weight.
