Interactive effect of genotype and environment on heterosis of panicle traits of rice (Oryza sativa)

Abstract

Abstract: Based on two years experiment data, and using the models of genetic effects and genotype×environment (GE) interaction for additive dominant additive×additive epistasis, this paper analysed the heterosis of panicle traits of rice (Oryza sativa). The results indicated that the heterosis of seven panicle traits was affected by both genetic and environmental factors. Asignificantly positive heterosis over mid parents based on population mean (HMP) was observed in spikelet number of main panicle (SMP), main panicle length (MPL), total length of primary branches (TLPB), total length of secondary branches (TLSB) and spikelet density (SD), while the reverse was true in the case of the numbers of primary branches (PB) and secondary branches (SB). The predicated results of GEinteraction showed that its positive effect was observed in SMP, MPLand TLPB, negative effect was found in PBand SB, while different directional effect was detected in SDand TLSB. Aheavy panicle type structure could be easily obtained from hybrid progenies by using IR66158-37(P₁), IR65600-85(P₂), Minhui 63(P₄) and R669(P₆) as crossing parents, which could be used for the breeding of super high yielding varieties of rice.

Key words: Oryza stativa, Panicle traits, Heterosis, Genotype×environment interaction, Additive×additive epistasis
