Genetic diversity assessment in garden pea (Pisum sativum L.) germplasm through principal component analysis

Abstract

The present study was undertaken to evaluate thirty garden pea genotypes for ten quantitatively yield related traits and Fusarium wilt response. Analysis of variance of present study indicates that there is lots of variation with reference to traits of garden pea genotypes which has to be quantified for using in pea improvement programme. Fusarium wilt response of different genotypes reported range from 6.5-95.25%. The PCA used to eliminate the redundancy in data set revealed that all the 10 quantitatively measured traits including Fusarium wilt response have been loaded on first five components.Based on Ward’s cluster analysis, the genotypes were grouped into three genetically diverse clusters.
