Performance of two and six row barley (Hordeum spp) genotypes under different dryland environments


Eight of barley pedigrees where compared to one six row adapted cultivar Acsad 12 and another six row adapted cultivar Acsad 14 in an field experiment at two locations of Erbil province (Einkawa and Koya) for three barley growth seasons during the period of 1993 – 1996, resulted in different effects on vegetative and reproductive growth in addition to yield and yield components as the significant best performance was at the third season 1995-1996 and in koya location while the lesser performance was at the first season and Einkawa location , most of the pedigrees overpassed the local well adapted control cultivars in many of the studied traits , especially as the two row pedigree P5 which yielded 610.39 g grains m-2 and 1569.4 g m-2 of biological dry mas followed non-significantly by the control Acsad 14 ,as well as the highest grain yield (754.93 g m-2)and biological yield (1650.9 g m-2) were performed season3 and season 1 respectively .Koya location produced significant higher mean values of 541.72 gm-2 and 1560.9 gm-2 of grain and biological yield surpassing Einkawa location by 1.2% and 1.23% respectively.
