Study on quantitative traits of international winter and facultative barley genotypes
2015
Koocheki, Ahmad Reza
To select and release high-yielding and adaptable barley varieties for cold zone, are used introduction varieties containing desirable traits(high-yielding, resistance to diseases, high quality, and adaptable) in addition to national varieties. In this study, two barley nurseries from ICARDA including: one yield trials IBYT – W and one observation nursery were evaluated. Yield trials experiment were conducted using latic design with two replications and 25 genotypes. Variance analysis of grain yield showed significant difference among genotypes in Ardabil station. However ,none of the genotypes had a yield higher than checks in locations. Genotypes 17 , 19 and 18 had the highest yield respectively. In observation nursery, IBON -W, was evaluated and selected 3 genotypes. Overall, taking into consideration plant height and type, early maturity, resistance to diseases and lodging, cold tolerance and grain yield, 8 genotypes were selected and conducted to preliminary experiments of cold zone in next year
