Abstract
Yield is a complex character. Hence selection for yield per se is not as effective as through its Components. Yield in cotton, like its other components, is greatly influenced by environment. Thus, genetic variability in the material for yield traits would form the basis for real achievement in their improvement. The relative magnitude of different sources of variation is of great practical importance to the Plant Breeder in planning and successful implementation of his hybridization and selection programme. The heritability estimates further provide the basis to quantify the variability in the material in hand. Meredith and Bridge (1971) reported that undesirable Linkage could be broken by intermating and hidden variability released to form new combinations, which results in high variability and genetic advance. Thus the present study was undertaken to estimate the variability and genetic Advance for yield and its components in two populations derived from a single cross of two upland cotton varieties.
