Association and path analysis in the selections made from colour tinted Gossypium hirsutum cotton germplasm

摘要

Fifty one single path selections of different colour linted genotypes of Gossypium were evaluated in a randomized block design with three replications during kharif 1997-98. Analysis of variance revealed highly significant differences among genotypesfor all the traits studied. High estimates of GCV, heritability and genetic advance were observed for seed cotton yield/plant, number of bolls/plant and plant height indicating that selection would be effective for these traits. Seed cotton yield/plant exhibited significant positive association with number of bolls/plant and plant height. Number of bolls/plant also exhibited positive and high direct effects on yield. It was concluded that number of bolls/plant was the most important component characterfor selection of genotypes with high potential of seed cotton yield.
