water deficiency is one of the most important risk factor decrease production and genetic variation in the crops.Therefore produce and breeding of new varieties is main aim at breeding program in this regions.In this investigation bread wheat lines evaluated different series contain preliminary bread wheat yield trail (PBWYT), bread wheat yield trails(BWYT-A1,BWYT-A2,BWYT-BT)r.a ils of PBWYT , BWYT-A1,BWYT-A2, BWYT-B 118 each one were cotain 118,20,20 and 81 lines, respectively. selection based on performanced chractristics of day to heading, day to matuarity of physiological, plant hieght, kernel thousand weight, yield, phenotypical type in farm, weight test of seed and responsible to pests and pathogenes. Based on results , selection for earliness can to been selection high yield and kernel thousand weight lines. In preliminary bread wheat yield trail based on earliness selected 3,10,20,30,50,75,85,87,88,90 and 117 lines. In addition to this lines were high yield. In BWYT-A1 than more of lines for yield located in check class. But no lines would rather not check. In this Trail selected 1,2,3,6 and 8 lines for participation in B-test trail of next year. In BWYT-A2 Trail based on reporte characteristics in above,2,4,5,8,9,14 and 16 whold rather of check, but no significantly difference check. In final selected lines in this trail participated B-test trail next year. In B-test trail than more of lines for yield located in check class, only line of No.57 higher yield to check,5% level probability.ln addition to would rather lines of 13,16,19,32,36,37,38,42,46,56,58,66,70,71,72,73 and74.
