TAILIEUCHUNG - Genetic diversity studies on parental and interspecific hybrids (Gossypium hirsutum L. × Gossypium barbadense L.) of cotton

Genetic diversity analysis was conducted at Main Agricultural Research Station, University of Agricultural Sciences, Dharwad during Kharif, 2017. In this study, 35 genotypes were evaluated for 11 yield and yield attributing traits and grouped into four clusters through Mahalanobis D2 statistic. Cluster I was the biggest with 23 genotypes followed by cluster II, III and IV. Among eleven characters studied, seed cotton yield ( %) and days to 50 per cent flowering ( %), contributed high for divergence while other characters like boll weight ( %), number of sympodia per plant ( %) and lint index ( %) contributed very little for divergence. Cluster IV with solitary genotype secured 1st rank with an overall score of 20 across 13 characters and the cluster III obtained 4th rank with an overall score of 34. As high inter-cluster distance is shown by cluster III and IV, hence is desirable to select genotypes from these clusters to develop triple cross hybrids for further crop improvement programs. | Genetic diversity studies on parental and interspecific hybrids (Gossypium hirsutum L. × Gossypium barbadense L.) of cotton
