چکیده
|
Twenty pakistani date palm cultivars from nine different geographical regions were characterized to estimate the polymorphism and possible similarity level. nineteen morphological traits were explored and subjected to principal component analysis (pca),cluster analysis (ca) and correlation index. the results brought out important differences in phenotypic characters in all date palm cultivars. principal component analysis (pca) indicated that all quantitative traits along with number of wings,frequency of wings,seed surface and seed shape were highly divergent. similarly cluster analyses (ca) also revealed morphological variability among date palm cultivars and,some relationship and heterogeneity was also observed within cultivars of the same origin. © 2015 university of agriculture. all rights reserved.
