Multivariate and RAPD marker analyses in ashgourd genotypes.

摘要

Genetic diversity of 25 ashgourd genotypes collected from different geographical locations was assessed at the molecular level and compared to morphological traits for degree of divergence. The clustering pattern based on Mahalanobis D2 statistic indicated that there was no association between geographical distribution of genotypes and genetic divergence. The cluster profile, based on quantitative data and RAPD markers, revealed that morphologically distinct and superior lines were genetically differentiable. Also the RAPD analysis gave a perfect discrimination of waxy textured group from smooth textured group, which is in line with morphological characterization.
