Grouping of Lines and Different Cultivars of Barley in terms of studied traits in Laboratory Condition

Grain used as food by humans long ago and today, a variety of grain products is prepared. This study was conducted in a randomized complete block design (CRD) with three replications at the Agricultural Laboratory of Islamic Azad University of Ardabil. For grouping the genotypes, clustering analysis by Wardʹs method using Euclidean distance based on the average standard, 6 evaluated attributes were done in the laboratory and 39 lines with cutting in Euclidean distance underwent in five groups. Diagnosis function analysis also confirmed this grouping. In analysis of variance between groups in terms of all traits, results showed the most significant differences between the groups at 1% level that confirmed grouping. The second group were consists of Radical and Tokak control cultivars and lines 2, 3, 10, 12, 14, 29, 32, 33 and 34 which had more value and were in the first grade in terms of the characteristics such as the coefficient of velocity of germination (CVG) and germination rate (RS) and had lowest value and were in the end grade in terms of the characteristics such as the Mean Time Germination (MTG). The results showed that the results showed that the was fourth group with lines 1, 7, 8, 9, 18, 19, 20, 24, 25, 26, 28, 30 and 31 among the four groups as a superior group, because whatever coefficient of velocity of germination (CVG) and germination rate (RS) is low is better.
