| Abstract | ||
| Twenty new bread wheat genotypes in addition to the local variety Abo-Graib 3 were evaluated in Nienavah governorate for Al-Rashidia and Rabeeah locations. The characters studied were: number of days to flowering, plant height, spike length, number of spikelets/spike, number of grains/spike, number of spikes/m2, yield and biomass yield, harvest index, 1000 grain weight and protein percentage. The genotypes were significantly different for all the characters except for the number of spikelets/spike. Phenotypic and genetic variances were significant for all the characters. Genetic correlation was significant between grain yield and harvest index for both locations. Broad-sense hertability estimates were high for protein percentage and low for plant height, grain yield, biological yield, harvest index and 1000 grain yield for both locations. | ||
