Abstract: 

The objectives of this experiment were to evaluate of genetic variation and relationships among 20 accessions of Bromus inermis. The experiment was conducted as a randomized complete block design with 3 replications. Results of variance analysis showed significant differences between the accessions for different traits. There was considerable phenotypic and genotypic variation for forage yield and number of stems per plant. Broad-sense heritability was very high (90-98%) for days to pollination, days to heading and plant height. For number of stems, flag leaf length, peduncle length, forage yield and crown diameter, broad-sense heritability ranged between 67-87%. Correlation coefficients showed that forage yield per plant had a high and negative correlation with days to heading and days to pollination, but a high and positive correlation with plant height, peduncle length, flag leaf length, flag leaf width, number of stems and crown diameter. Using principal component analysis, the first three components determined 90% of the total variation. Days to heading, days to pollination, plant height, peduncle length, flag leaf length, forage yield and number of stems per plant were the most important traits in first component. Accessions were classified into 3 groups with distinct variations for forage yield, plant height, tiller number and maturity time. Thus, crossing plants from genetically diverse populations may result in superior progenies for cultivar development.
