Abstract

Two fild experiments during 2 sesons for each. First at Massaa to study some genetic traits of some bread and durum wheat cultivars (Bjy , Kassi , Kofra 1 , kofra 2 , Vee , Kareem , Salamboo mo , Icsaad 901 , Giza 168 , Binswaf , Marjawii and Sakha 69) under supplemental irrigation comparing to rainfed. Second in Gandoula south Al-Jabal Al-Ahdar to stydy the same traits at different levels of alimmonium phospats 18 : 46 (0 , 70 , 140 and 210 Kg ha^-1) within the cultivars(Slamboo80 , Sham10 and Abo Elkhair). The genetic traits concentrated on coefficients of genetic variation GCV m phenotypic variation (PCV) m genetic advanced (Gd) and broad sense heritability (H²) through the 2 growing seasons 2013 - 14 , 2014 – 15. 1^st experiment layout in strip plot with 4 replicates’ , irrigation state in the strip and cultivars in the sup plots , more over the 2^nd experiment layout in split plot by 4 replicates , cultivars in the main and fertilizer levels in the subplot. The results showed decline in genetic traits regarding to plant height , no effective tiller m^-2 , spike length , wt of spike grains , biological , grain and straw yield , harvest index , 1000 grain wt and grain protein content (%) due to closely related witch profit in breeding programs because all cultivars having highly H₂ under the factors of these experiments.
