بررسی عملکرد دانه لاین های متحمل به شوری گندم نان در شرایط زارع اقلیم گرم کشور

In order to compare the yield of new wheat varieties and lines tolerant to soil salinity including SS-83-3, SS-85-6, SS-85-10, SS-85-11, SS-85-14, SS-85-20 kavir and sistan as check this research project was conducted, a farmers conditions in different locations (Khuzestan (Ahwaz), Sistan and Baluchistan (Zabul) Rostam Abad and Ershade) under saline soil conditions in complete block design with four replications . All experimental condition including, seed density, sowing date, rate of chemical fertilizers and weed control were used based on the region took place. Finally, based on yield index ratio(YIR) and ranking method four lines including 3,4,5 and 6 with overall yield, respectively, 4200,4320,4510 and 4333 kg per hectare and YIR 104,107,112 and 105 rank 4.3,3,2.67 and 5.32 SDR of 3.51,1.00,1.53 and 4.04 compared with the control cultivar Sistan yield 3930 kg per hectare, YIR 97 and rank 5.33and SDR 3.52had good performance and stability for performing the research and extension projects are proposed.
