In order to obtain varieties with suitable traits such as resistance to diseases and other unsuitable environmental condition and with favorable qualitative characteristics for pasta and based on the role that usage of improved seed may have in increasing the yield, these experiments were sown with four replications with the exception of the preliminary test and every plot consisted of six rows 20 centimeters apart. At harvest 0.5 meter from the end of each bne were eliminated as border effect. Bland B2 tests had 20 lines and varieties. The experiment in B test were randomized complete block design replicated four times. The checks were Aria and Tajan . The evaluation of the varieties and lines for grain yield were done by analysis of variance and comparison of the lines and varieties were done by LSD. In B 1 test , eight lines were selected which had higher yield than that of the check and were suitable on the basis of agronomic characters and resistance to disease, In 82 test, three lines were selected for agronomic traits and resjst~nce to diseases. Key words: lines- comparison of the means - randomized complete block
