Ecotypes and genetic divergence among sympatrically distributed populations of Hordeum vulgare and Hordeum spontaneum from the xeric region of Jordan

摘要: The progeny of paired samples Hordeum vulgare L. and spontaneum C. Koch, collected from Jordan's xeric region was used in this study. Statistical analyses seven easily measured morphometric traits were to elucidate the relationships distances between populations both species, detect any ecogeographical races, study interrelationships adjustments under Flag leaf area plant height two most important discriminating variables which totally separated accounted for 85.3% total phenotypic variance collection. Cluster analysis indicated that level divergence among species considerably different. Populations clustered at a maximum Euclidean distance 2.08, while 1.49. Three ecotypes each identified. These corresponded environmental range collection sites. adjusted different ways as revealed by principal components analysis. Sampling clusters identified is expected increase allelic diversity selection breeding purposes.
