Abstract:

The hereditary parenthood of genepool plays important role in crop improvement. D2 statistics is a powerful estimating the magnitude of genetic diversity. Comparative study was conducted to estimate the genetic distances among ten parental lines of upland cotton in two different sets of environments indicated the varying pattern of genetic distances along with varying pattern of dendograms revealed the role of environmental factors controlling expression of quantitative characters and subsequent magnitude of genetic diversity estimates. Clustering based on D2 analysis provides a statistical tool for selecting the diverse parents for hybridization program. The D2 distances matrix calculated for Environment (E1), Environment (E2) and average (E1 & E2) shown mean genetic distances of 15.38, 14.83 and 14.15 respectively. Comparing D2 matrices among E1, E2 and average of environments (E1 & E2) revealed the significant effect of environment on genetic distances with mean values 0.56 (E1 vs E2), 0.82 (E1 vs Avg [E1 & E2]) and 0.62 (E2 vs Avg.[E1 & E2]). The average deviation of 0.82 was estimated for genetic diversity estimates over the environments. The recent techniques of molecular techniques (MAS) should be used for precise estimation of genetic diversity followed by clustering pattern for effective selection of diverse parents for exploitation of phenomenon of heterosis.
