The study of adaptability of salt tolerant advanced barley (Hordeum vulgare) genotypes grown in moderate regions

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.
