Genetic diversity and phylogenetic relationship through the use of microsatellites in Gossypium hirsutum L.

ABSTRACT: Enhancing cotton yield and fiber quality is challenging due to the limited genetic variation, highlighting the need for efficient use of germplasm resources. Therefore, 10 morpho-physiological characters and 10 simple sequence repeat (SSR) markers were used to investigate the genetic variability of 50 cotton genotypes. Principal component analysis and Mahalanobis' generalized distance (D2) were applied to morpho-physiological data. Two principal components presented 53.83% of the cumulative variability in the raw data on biomass-related variables. Four different clusters were exposed by cluster analysis (D2): Cluster I included 20 genotypes, whereas clusters II, III, and IV had 6, 18, and 6 genotypes, respectively. Intra-cluster distances were highest in Cluster IV (222.79) and Cluster I (
