الملخص الإنجليزي

Breeding barley for high yield and other desirable traits is a dire need of the day.

Five cultivars and pure lines of two-rowed barley (Hordeum distichum L.) with their twenty F1 progeny were evaluated at Kurdistan Region-Iraq at three different locations, Sulaimani, Erbil and Kalar during the winter season 2011-2012 using randomized complete block design with three replications.

Various plant phenotypic traits as number of days to 50% anthesis, flag leaf length, plant height, number of days to 50% maturity, biological yield plant-1, number of tillers plant-1, number of spikes plant-1, peduncle length, peduncle diameter, average spike weight, spike length awns length, number of Spikelets spike-1, number of grains spike-1,1000- grain weight, harvest index and grain yield plant-1 were investigated.

Means comparison were carried out using least significant differences (LSD) test (P≤ 0.05).The results of study revealed highly significant mean squares in different locations for all studied traits.

Qilyasan location exceeded significantly in all studied traits except for the traits, tillers plant־¹ and spikes plant־¹.

Stability and genotypic resultant were also estimated.

Genotypes mean squares showed highly significant differences for all traits at each location.

The study of stability and genotypic resultant revealed the presence of highly significant effects due to genotypes x locations in all studied traits with exception of the peduncle diameter which was merely significant.

Peduncle diameter had the highest stability and genotypic resultant with average values 0.951 and 0.951, respectively , while grain yield plant־¹ manifested the lowest were 0.459 and 0.450, respectively.

Better genotypic resultant were observed in two genotypes viz., parent 3 and hybrid 5x2 having high grain yield plant־¹ value with 0.602 and 0.567, respectively.

These were found promising for wide adaptation over sites across environments
