| Abstract | ||
| The study included evaluate of stability twenty four genotypes of Barley ( Eighteen in torduced genotypes which are advanced lines from selection program by method of pedigree in isolated filialles for crosses introduced from (ICARDA) with six local varieties Shuaa , Boraq , Emal , Samir , Warkaa and Al- khair) , obtained from Ministry of Science and Technology - Salahaldeen province , to know its stability in way of cultivate it in three tillage system (Deep moderate and without tillage) in tow locations , first in one farmers field in Tuz location , the second in field crops station-college of Agriculture . Tikrit University in 2013-2014 season used (RCBD) Randomized Complete Block Design in split plots system , the main plots were Tillages and the sub plots were the genotypes with three replicates It was compared to evidence franchise Safety First using the variation across environments (EV) and Eberhart and Russel (ER) and Finlay and Wilkinson (FW) and Shukla (SH). the interaction between the genotypes and tillage systems and the locations for plant height , flay leaf area , number of spike/m2, fertility ratio , number of spike grains and weigth of 1000 grains trpits was significant at 1% prob . level , and at level 5% of prob . was for two traits of number of tillers/m2 and spike length and it was non significant for other traits . the genotype (warkaa) was distinguished in plant height traits (111.29cm) and leaf aerea trait and the genotype (D4) in two traits of duration to 75% flowering and the duration to physiological maturity and the genotype (D6) in traits of spike length and weight of 1000 grains, and the genotype (D7) in two traits of number of tillers and number of spike/m2 and the genotype (H4) grain yield and biological yield . the genotype (JH7-1) was in the first stage in grain yield as the indexs (FW and SH) and in the second stage as the index (EV), while was in the second stage as the index (SH) . the genotype (JH21) was in the first stage as the index (ER) distinguished in the grain yield trait and in the second stage as the two indexes (FW and SH) it was a distinct note in the highest averages for this trait. | ||
