Abstract: (2046 Views)
Salinity stress has an important role in reducing crop production. There is a possibility of cultivar diversity use in desirable traits selection under stress. This research was carried out in order to test of different salinity level on yield of barley (Hordeum Volgar L.) genotypes, in the split plot experiment on the base of Randomized Completely Block design in 3 replications. Salinity treatment involved 5 levels: S1(control)=EC 4.5 ds/m, S2=EC 7.5 ds/m, S3=EC 10.5 ds/m, S4=EC 13.5 ds/m and S5=EC 16.5 ds/m as main plot and subplots were 9 genotype involved promising lines and varieties. The effects of Salinity treatments studied by sampling on yield of genotypes and using stability parameters. That based on Shukla stability variance, Wricke ecovalance and Eberhart and Russell regression model the STW82153, MBS8715 and Valfajr genotypes and based on Romero environmental variance the MBS8712 genotype exhibited the most stability. The best performance in all salinity levels was shown by genotypes STW82153، MBS8715، ESBYTM8910 and Valfajr. Genotype MBS8712 showed the least change with increasing salt concentration and with the improvement of environmental conditions, genotypes MBS8715 and WB7910 had the highest production capacity. The results indicated that used stability parameters would be useful for simultaneously selecting for high yield and stability under salinity conditions.
