Abstract

In order to study the genetic variation and selection of high yielding barley lines with desirable agronomic traits, 108 pure lines in the non-repeating Augment design with four controls in three blocks were evaluated using the Selection Index of Ideal Genotype (SIIG). The experiment was evaluated in the farm of Darab Agricultural and Natural Resources Research Station in the period of 2017-18. The results of the SIIG index indicated that Lines No. 64, 8, 33, 113, 119 and 34 with the high value of SIIG (0. 770, 0. 746, 0. 744, 0. 712, 0. 705 and 0. 705, repectively) were superior genotypes and lines number 44 and 116 with the lowest SIIG (0. 149) were the weakest lines in this study. In order to evaluate the efficiency of SIIG index in selecting the best lines for grain yield, thousand kernal weight, plant height, days to heading and days to maturity, lines were grouped according to SIIG index in 6 categories. The results showed that as the amount of SIIG index decreased, yield, 1000 grain weight and plant height were also decreased, but there was no significant change in the days to flowering and days to maturity. The results of grouping of lines based on SIIG showed that the average grain yield of groups 1 and 2 were higher than the average yield of the all controls. Also, mean yields of groups 4, 5 and 6 were lower than all four control genotypes. Finally, lines number 64, 8, 33, 113, 119 and 34 )Group I) and lines number 87, 65, 85, 115, 32, 6, 86, 2, 15, 13, 9, 57, 62, 63, 28, 14, 89, 94 and 16 (Group 2) and Lines number 22, 10, 46, 55, 114, 96, 104 and 25 of (Group 3) were the best Lines and can be used for further testing, including adaptation tests in tropical areas, especially Darab. Also, line 113 was the top two-row line in this study.
