Abstract:
Prior information on genetics and gene action of desirable traits in parents is prerequisite for development of strategies of breeding programs of the crop plants. The components of genetic variation are crucial factors determines destiny of breeding. Assessing genetic variation among genotypes to be utilized as parent in crossing program is paramount importance in harnessing accelerative genetic gain with precision. Results of the study shown the that numbers of gene involvement in breeding value, additive (d) effect and dominant × dominant (l) gene interaction were the only significant portion of gene controlling plant height, number of effective tillers, grain yield per plant, spikelet fertility and percent survibility under submergence stress. The additive and dominance gene effects were found important in managing submergence stress in rice. The plus sign in the additive gene effect implies that rice variety Hasanta contributes positively to the trait as compared to Swarna Sub1 and vice versa.
