| To study the genetic variability of agronomic characteristics in winter barley landraces collected from western parts of Iran, 32 landraces and four improved cultivars/lines as checksEBYTC74-2, EBYTC74-10, EBYTC74-12 and Makouee were examined using randomized complete block design with three replications in Agricultural Research Center of Lorestan in 2001 cropping cycle. Twenty three agronomic characters were measured according to instructions of IPGRI. Analysis of variance indicated significant differences among entries for all characters. This analysis also showed high genetic diversity within the germplasm. The two-row landrace barley from Gilan Gharb yielded 6054 kg.ha-1 which was significantly different from the yield of checks and other landraces. Grouping of landraces by cluster analysis resulted in three clusters. Most of the entries within clusters corresponded with their geographical origin. However, some discrepancies existed that could be due to exchange of germplasm between geographical regions, or because of unknown origin of some landraces. Broad sense heritability of grain yield and its components, such as umber of fertile tillers, main spike length, No. of grains per main spike and 1000-grain weight, were 0.79, 0.82, 0.98, 0.93 and 0.93, respectively. Because of high heritability, genetic coefficient of variation and genetic gain, it is possible to select superior genotypes for hybridization and developing superior lines. |
