Sixteen Pakistani date palm cultivars from diverse origins were characterized morphologically to assess the similarity level, the overall point of polymorphism and important agronomic traits existing in the germplasm present in Pakistan. Forty two qualitative and quantitative features were explored and subjected to multivariate analyses. The results brought out important differences in phenotypic characters in all date palm cultivars. Principal component analysis (PCA) indicated that trunk length and diameter, total number of leaves, rachis length, leaflets length and width, number of leaflets per side, number of pinnae planes, length and grouping of spines were highly divergent. Similarly cluster analyses (CA) also revealed phenotypic diversity among date palm cultivars and, some close association or heterogeneity was also observed within cultivars of the same origin.
