بررسی صفات کمی و کیفی گندم های نان در آزمایشات مقایسه عملکرد یکنواخت سراسری مناطق گرم ‭ERWYT-SALT‬

In order to study and evaluate tolerance and adaptation to salinity, wheat bread, 20 Lines in Ahvaz and Zabol under salinity soil conditions in the two crop years in the 2008-10 in randomized complete block design were three replications. Average yield based on the total, non-parametric methods ranking (Ranking) using the average performance rating (R) and Standard Devition Ratio (SDR) and Yield Index Ration (YIR ) And good agronomic characteristics were selected superior cultivars. Lines 5,13 and 15 with the 4237, 4661 and 4399 kilograms per hectare and YIR 110, 120 and 113 and SDR 6.81, 7.00 and 1.53 respectively in terms of soil salinity between 14-10 dS during the growing season as the top line to participate in adaptive research and extension projects in areas of warm saline were selected. Study of germination percentage and dry weight seedling (Root and stem) and speed of germination, showed that lines 3, 5, 6 and 8 in the salinity levels of 250 and 350 mM in stage of germination and seedling establishment than in terms of laboratory have tolerance to salinity.
