Abstract
Genetic divergence studies were taken up using 55 genotypes for yield and its contributing traits using D2 statistics in upland cotton. Based on D2 values, the grouping was done and the 55 genotypes were placed in six groups and six principal components explaining 91.8 per cent variability. Results of the multivariate analysis indicated that maximum divergence among genotypes L1785, L1687, L1748, L1780, L1783, and L 604 was detected indicating that the crosses between these genotypes will produce highly heterotic hybrids.Genetic divergence studies were taken up using 55 genotypes for yield and its contributing traits using D2 statistics in upland cotton.
