Abstract
This study was to evaluate the adaptability of ten salt tolerant advanced barley in six regions (Esfahan, Kerman, Yazd, Ghom, Mashhad and Gonabad) in 2002-03. Statistical design was a Randomized Complete block (RCB) with three replications. Electrical conductivities of irrigated water and soil in all regions were at least 8 ds/m and 10ds/m, respectively. Combined analysis of variance revealed interaction of genotypes * regions and genotypes were different significantly at 1% and 5%, respectively. Genotypes No. 4 (LB.Iran/una 8277//Gloria”s”/Come “s”-11M/3/Kavir) and No. 5 (73-M4-30) produced the highest grain yields (4616 and 4581 kg ha-1, respectively). Mean grain yields of Nosrat and Walfajre (checks) were 4167 and 3596 kg ha-1, respectively. Stability analysis on grain yields based on parametric method of C.V. % and non-parametric method of rank showed that genotypes No. 4 and No. 5 were most stable genotypes. Therefore, due to high grain yields, mean of genotypes No. 4 and No. 5 in all regions were selected as adaptable and salt tolerant genotypes.
