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

At present,Considerable level of agricultural lands located in different climates of the country such as Yazd , Esfahan, Kerman, Qom , South of Khorasan ,Fars , Sistan and Bloochestan and Markazi province are under the stress of water and soil salinity .In such white about 14.2% of countries and was been salt about half of stress of water land. So we should find figures that can tolerate the limitation of above conditions and have had consistency with high economical performance: in this regard, four promising salinity tolerant wheat lines selected from uniform tests of consistency M3S4-84,85 including (MS-85-12,15 , 17, MS-84-13 ) along with 3 Bam and Arg And Kavir cultivars) in the form of random complete blacks design in 4 repeatation and in Tabas region was performed under the salty soil and water conditions(EC=17.86ds/m soil and EC=7.34ds/m water) and in Abarkooh region was performed under the salty soil and water conditions(EC=9.85ds/m soil and EC=4.8ds/m water) in cropping season 88-89 . Every treatment is in 24 rows with 6.5 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 weighted and analyzed on the basis of related statistical design the results showed that. The lines (MS-85-15 ) and MS-85-17 were better than the check( Bam , Arg and Kavir) in two regions (Abarkooh and Tabas) the line(MS-84-13) was better than Bam and kavir in Abarkooh and Tabas , respectively and have increased their performance in the Abarkooh (tables 5).
