In the respect of water deficiency problem in region specially at late growth stage, of wheat that overlape with spring crops planting season, so introuduction of wheat genotypes that tolerate late season stress on seed filling stage with minimum yield decrease ,can resolve this problems. In this experiment 6 promising drought tolerant wheat lines with two checks (pishtaze and Roshan) were used as RCBD design with three replications in Giv village as on farm condilon. Characteristics such as days to heading (DHE) , days tomaturity (DMA), plant height (PLH), number of spike per m2 , spike length, peduncle length thousand kernel weight, (TKW ),and grain yield were measured. Analysis of variance showed that there is significantly difference at % 1 level for PLH peduncle length. DHE , DMA and number of kernel per spike ,among lines and variaties . Grain yield in all lines were better than Roshan but as the same with pishtaz but line WS-82-9 with grain yield of 4.3 ton/ha and with thousand kernel weight as 41.5 gr and Number kernel per spike with 52.4 was better than the checks and were selected for extentional research desing
