Genetic Dissection of Interspecific and Intraspecific Hybrids of Cotton for Morpho-Yield and Fiber Traits using Multivariate Analysis [link]Paper  abstract   bibtex   
To estimate level of genetic diversity various cotton genotypes, inter and intraspecific hybrids were assessed for yield, yield contributing and fiber traits using various multivariate analysis such as principle component analysis and linkage cluster analysis. Principle component analysis (PCA) exhibited that first four PC out of nineteen PC, with eigen value \textgreater1, contributed about 80.326 % of total variability. Positive contribution towards PC1 was given by seed traits such as lint/seed, seed weight/seed, boll weight, seed index and seed cotton/seed. In biplot analysis, intraspecific hybrids and their parents were present very close to each other while interspecific hybrids, their parent and exotic line were unsimilar and far apart from intraspecific hybrids. Results of linkage cluster analysis (LCA) revealed that among four clusters, performance of genotypes in cluster 3 was superior. PCA and LCA showed that interspecific hybrids showed highest diversity from intraspecific hybrids and concluded that intraspecific hybrids had narrow genetic basis, which can be altered by using interspecific hybrids or exotic lines. These genotypes can be exploited for variety development with enhanced level of diversity, fiber quality and seed cotton yield.
