Abstract

Genotypic and phenotypic correlation co-efficients and path co- efficients were worked out in 51 diverse, genotypes of upland cotton. Number of bolls per plant and plant height had positive correlation with seed cotton yield both at genotypic and phenotypic levels. And these two characters showed significantly positive correlation between themselves also. Path co-efficient analysis indicated that plant height, bolls per plant, ginning out turn, lint index and seed index contributed directly to yield.
