Abstract: (3301 Views)
To evaluation of genetic parameters of rooting traits in 50 doubled haploid barley lines, a factorial experiment based on CRD was carried out at the agronomy lab of the Zanjan University Analysis of variance showed significant differencesfor all rooting traits:material transfering speed, germination percent, angle, diameter, fresh and dry weight, surface area, cumulative length, the length of the longest root and the hairy root length. The calculated narrow sense heritability was medium for all studied rooting traits except dry root weight (15.11 and 23.40 in normal and stress conditions). Based on the genotypic correlations, it was found that there were positive and highly significant association normal and salt stress conditions, especialy between trait the length of the longest root and traits cumulative root length, root surface and fresh dry root weight. Since, the length of the longest root and cumulative root length and root surface offered as suitable traits for evaluating and selecting the genotypes in breeding programms.
