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

In the respect of high quality water resources defficiency in the world so use of saline and partial saline water is nessecary of the farmers. one application method for using saline water is using of plant genetic diversity and then development and selection of adapted and tolerant genotypes under salinity stress (saline water and soil condition) in this study 3 promising salinity tolerant lines including ERWYT_Salt(81) Numbers 5,7 and 14 with checks (roshan and kavir) were used in RCBD design with three replication in Amir Abad (field research university of birjand faculty of agriculture). electrical conductivity of irrigation water and soil was 11 and 14.1 ds/m respectively. characteristics such as days to heading (DHE), days to maturity (DMA), plant height (PLH), Peduncle lenght, thousand kernal weight (Tkw) and Grain yield were measured.analysis of variance showed that theres is significantly difference at 1% level for PLH, peduncle lenghth and TKW among lines and variaties.line number 14 with 4.7 ton/ha grain yields was better thean the checks and was selected for extentional research designs.
