摘要: ABSTRACT Univariate and multivariate analyses numerical taxonomy procedures were utilized on the standardized mean values of 17 quantitative traits in base collection wild emmer wheat, Triticum dicoccoides Korn., from Jordan, an effort to identify ecotypes by trait measurements. Five identified basis morphological, developmental, productive traits. The five exhibited different adaptive complexes as revealed principal component pairwise correlation analyses. It is postulated that particular environmental conditions across distributional ranges species Jordan resulted evolution gene which are conserved genetic linkage or natural selection. represented marginal, peripheral, central range country. Two extreme three intermediate recognized. represent “grassy” “robust” types recognized earlier. ...
