ABSTRACT: Biparental mating ( BIP ) attempted in the F2 of a cotton cross Giza 75 X Karshencky2 to know the relative efficiency of biparental mating over F3 selfed in turns of release of genetic variability and to know the shift in the association pattern of components of various characters in cotton. Sixty biparental progenies and sixteen F3 selfed progenies were then evaluated for six productive characters and five fiber quality properties. Analysis of variance revealed highly significant differences among intermated progenies. Biparental, intermated progenies, proved its superiority over selfing by registering high mean values in desirable direction for all characters. The range in intermated population was wider as compared with F3 selfed population. The lower limt of range was high in BIP, in the same time the upper limt was higher for most the characters suggesting that intermating helped in releasing more variability. High genetic variability combined with high heritability in broad sense was noticed in biparental progenies for all characters under study. The magnitude of non-additive were largely in biparental for all characters as compared with F3 selfed. However, the magnitude of additive component was larger in F3 selfed population for most characters. This could be emphasized by high narrow sense heritability. Correlation studies indicated that, several new associations in terms of direction and magnitude was observed. The undesirable strong negative association that existed among the characters related with yield and quality in F3 population were proken or converted into non-significant and positive upon intermating. This was attributed to breakage of undesirable linkage by forced recombinations induced by biparental mating, thereby offering a great scope of selecting new recombinants combining both yield and quality characters in intermated progenies and could be used in cotton breeding program
