Present investigation was taken up with the objective of studying the impact of biparental mating on linkage relationship among the grain quality parameters of rice. Association analysis revealed that, none of the grain quality parameters had significant positive association with grain yield except hulling parcentage in BIPs. A total of eighteen positive and significant associations in F₂s and 20 positive and significant associations in F₃ progenies were observed. But it was increased to 32 positive significant associations in BIPs. Like wise, negative association was also reduced in biparental progenies and it was only 10 negative associations in BIPs. But 23 negative associations in F₂s and 12 negative associations in F₃ progenies were observed. It indicates that, inter correlations among the grain quality parameters were strengthened in BIPs and several new recombinants were synthesized in BIPs due to intermating in F₂ population. Several such new associations were observed among the grain quality parameters in BIPs than other two segregating generations (F₂ and F₃ generation). It was evident that reshuffling of genes were responsible for correlations among some characters resulting newer recombinations which presumably, were due to changes from a coupling to repulsion phase linkages.
