بررسی و مقایسه عملکرد ارقام و لاینهای گندم متحمل به شوری در شرایط زارعین

At present, Considerable level of agricultural lands located in different climates of the country such as Yazd province are under the stress of water and soil salinity, and according to two climates from four main climates of aquatic wheat cultivation in the country which are under non-living environmental limitations especially hot weather, drought in the end of the season and salinity ,with 11.292 thousand hectares are about 57% under the level of aquatic wheat cultivation including regions from agricultural lands in Esfahan, Kerman, Qom, southern parts of Khozestan and Fars, Sistan and Baloochestan, Markazi and Yazd. We should find figures that can tolerate the limitation of above conditions and have had consistency with high economical performance: in this regard , six promising lines of wheat tolerant whit salinity selected from uniform tests of consistency M3S4-81 and MS-82 including (MS-81-5, MS-81-7, MS-81-14, MS-82-6, MS-82-7, MS-82-19) along with 3 desert and bright evidence,4 lines of salinity in the form of random complete blacks design in 4 repetition and in 2 points of Ardakan(EC=13ds/m soil and EC=11ds/m water) and Abarkooh(EC=11ds/m soil and EC=9ds/m water)was performed under the salty soil and water conditions in agricultural years 84-85 .Every treatment is in 33 lines with 5 meters and 15 centimeter distance and 25 square meter area. The whole note-takings necessary during growth periods was done and finally the performance of terrace grain was determined and weighed and analyzed on the basis of related statistical design the results showed that. The lines (MS-81-14 and MS-82-7) were better than desert and bright evidences and have increased their performance (tables 2 and 5). Since the performance of line grain (MS-81-14) in Ardakan region was averagely 4.738 ton in hectare, showed the preference about 12.98 percent with difference about 550 kilogram as compared with desert evidence (average performance is 4.196 ton in hectare) and the same line (MS-81-19) in Abarkooh region was about 2.584 ton in hectare and with the difference about 554 kilogram to desert evidence, showed preference about 27.3% (average performance is 1.394 ton in hectare).
