Abstract :
A farm experiment was conducted to evaluate grain yield of wheat (Triticum aestivum L.) cultivars and elite lines in saline regions of Abarkuh and Khatam towns of Yazd province, Iran, in 2010-2011. The experiment was conducted as randomized complete blocks design with four replicates. Electrical conductivity for irrigation water in Abarkuh and Khatam towns were 8.3 and 4.5 dS m-1, respectively. Results showed that there were significant differences between two locations in grain yield, spike length and the grains per spike. The grain yield and the grains per spike for the cultivars were significantly different, regardless to locations. Shirodi cv. significantly produced lower grain yield than the others. Arg cv. and elite line MS-85-17 produced the highest grain yield in Abarkuh (4597.2 Kg ha-1) and Khatam (6149.3 Kg ha-1) towns, respectively. However, the grain yields for MS-85-17, M-83-17, Arg, Bam and Shirodi in both locations were 5053.8, 4496.5, 4982.6, 4208.3 and 2838.5 Kg ha-1, respectively. Based on the results, elite line MS-85-17 could be considered as new wheat cultivar for saline regions of Yazd province.
