GENETIC DIVERSITY IN SIX-ROWED WINTER BARLEY (HORDEUM SATIVUM JESS., SSP. VULGARE L.) GENOTYPES
Keywords:
genetic diversity, cluster analysis, principal component analysis, barleyAbstract
Twenty-five six-rowed winter barley genotypes were assessed for nature and magnitude of genetic diversity among them based of traits related to yield and quality of feed barley. The study was conducted in the Institute of Agriculture - Karnobat, during the period 2010/2011-2011/2012. Maximum variation was found for grain weight per a spike and spike length. The results of the present study showed considerable genetic divergence among the genotypes. This suggested that adequate scope is available for selection of superior and diverse genotypes for use in a programmed aimed at enhancing grain yield potential and grain quality of winter feed barley. Considering diversity pattern and agronomic performance the cultivars Konrat, Fedor, Zimur and Dobrinya 3 and breeding lines K-3.11 and K-3.12 might be selected as promising genotypes for future hybridization program.
