Abstract

This thesis embodies genetic analysis, combining ability, heritability, genetic advance and heterotic effects for different productive and quality traits of complete diallel cross of six cotton (Gossypium hirsutum L.) cultivars viz; CIM-109, CIM-240, CIM-1100, FH-682, BH-36 and CRIS-9 having diverse genetic origin. The detailed studies were based on data for F1 and F2 generations. The single plant selections made in F2 generation were also studied in F3 and F4 generations through plant progeny row method. Hayman's diallel analysis for genetic components of variation and Griffing's approach were employed to study the general combining ability (GCA), specific combining ability (SCA), the nature of gene action and their interactions for exploring possibilities of isolating useful recombination
