Genetic analysis for quantitative traits in rice (Oryza Sativa L.)


KK Barhate, DN Borole, VV Bhavsar, SS Sahane

The magnitude of dominance and dominance x dominance gene effects was recorded higher than additive gene effects for most of the character studied. Duplicate epitasis was observed for the character like plant height, Panicle length, productive tillers per plant, number of seeds per plant and days to 50% flowering in almost majority of crosses, while complimentary epitasis was observed for most of the cross combinations in test weight except KMR-1-41 x VL-311320 and seed yield except Indrayani x KJT-2.Additive and additive x additive gene effect were more effective than dominance in the charecters and crosses are improved by simple selection method. Significant epistastic gene effects coupled with duplicate epitasis indicating that the effective selection and transgressive segregents could be obtained in subsequent generations. The selection in such a case has to be postponed until virtual homozygocity is attended.
