A comparison between the performance and some qualitative characteristics of different wheat genotypes in salt stress conditions

ABSTRACT: To compare the performance and some qualitative characteristics different cultivars and lines of wheat in salty condition, five line of wheat including MS-87-4, MS-87-5, MS87-6, MS-87-7 and MS-87-8 along with four other genotypes as controls including Bam, Arge, Kavire and Afghan were selected. The experiment was performed in 2009/2010 growing season. The experimental design was randomized complete block with three replicates and 9 treatments. The results showed that there was a significant difference (p < 5%) in the 1000 kernel weight and the grain yield between the lines and species. Moreover, there was a significant variation (p < 1%) between the lines and species in the grain protein percentage, the grain hardiness percentage, the Zelni value and ash percentage. A comparison between the average of the treatments shows that Arge, which was cultivated as a control, had the highest grain yield (6.290 tons per hectare), followed by MS-87-7 (6.030 tons per hector), Bam (6.013 tons per hector), MS-87-6 (6.007 tons per hector), MS-87-5 (5.907 tons per hector) and Kavir (5.780).In addition, MS-87-4 had the highest protein percentage (16.067%), Zelni value (68.667%) and hardiness percentage (46.333%). Correlation analysis between traits indicates that there was a significant positive correlation between the Zelni value and the grain hardiness (p < 1%), and also there was a significant positive correlation between the number of seeds per spike and the seed and biological yield (p < 5%).
