In the station of agricultural research of Ardabil, among all the 248, in stead of primary efficiency comparison 27 lines which were superior in seed and agronomic features were chosen. No. 23, 26, 27, 28, 75, 149, 176, 179 genotypes respectively were the highest grain yield with considering the action of the 3166 , 3333 , 3266 , 3333 , 3800 , 3233 , 3333 , 3033, kg/ha respectively. in this experiment Azar2, had 1995 kg/ha grain yield. Analysis of variation in A and B experiments showed that in most of experimental lines.there were significant differences in grain yield. In genotype frequent examination, the number 11, 13, 16, respectively had higher evidences comparing to witness and were placed in A, B class. In the comparison of B1 Frequent activity the 5, 7, 23, 24, 25, genotypes, consuming 2296, 2288,, 2338,, 2254, 2325 kg/ha, and in the second examination the 1, 2, 10, 13, 16 and 25th respectively, producing 2050, 2033, 2100, 2025, 2229 kg/ha, and in the3rd examination the 1, 5, 6, 11, 12, 13 respectively producing 2195, 2146, 2175, 2450, 2729 kg/ha were the highest grain yield among the experimental lines.
