Five Traits Affected by Breeding of Indica-Japonica Hybrids

摘要:目的 水稻籼粳亚种间杂交具有强大的杂种优势已成为当前水稻育种关注的焦点，本研究旨在为籼粳交水稻育种实践以及水稻关键性状的遗传研究提供理论依据。方法 按照NC-II不完全双列杂交方式，选择14个亲本材料并配组48个杂交组合，采用植物数量性状的加性-显性遗传模型（A-D模型）分析生育期、株高与粒形相关性状等共计5个农艺性状的遗传效应、杂种优势及性状之间的相关性。结果 籼粳亚种间杂交稻生育期、株高、粒长、粒宽及长宽比等的加性方差分量占遗传主效应比率（VA/VP）比值分别为69.2%、74.2%、58.9%、66.0%和63.5%。广义遗传率（H2B）和狭义遗传率（H2N）的变幅分别为59.0%～99.6%和69.2%～98.9%，均达显著或极显著水平，主要受加性效应控制，且受环境影响小，在育种上早期选择有效。大多数的籼粳亚种间杂种一代的生育期、株高和粒形性状均呈负向中亲优势和负向超亲优势，杂交后代的生育期缩短、株高降低，长宽比介于双亲之间。籼粳亚种间杂交稻生育期是一个独立遗传的品种特性，株高与粒形具呈显著正相关。结论 在籼粳交育种上应关注生育期、株高，粒形等性状间的协调，有效利用杂种优势，培育强优势亚种间杂交稻新组合。Abstract:Objective Genetic improvement on 5 traits of rice through heterosis by hybridizing Indica-Japonica was analyzed.Method Following the NC-II incomplete diallel hybridization protocol, 14 rice parents and 48 hybrid combinations were generated for the analysis. Genetics, heterosis, and correlations of growth period, plant height, spikelet length, spikelet width, and spikelet length-width ratio of the varieties were evaluated according to the additive and dominant genetic effects.Result The ratios of additive variance component to phenotypic variance (VA/VP) on the growth period, plant height, spikelet length, spikelet width, and spikelet length-width ratio of the rice were 69.2%, 74.2%, 58.9%, 66.0%, and 63.5%, respectively. The variations of broad-sense heritability (H2B) and narrow-sense heritability (H2N) were 59.0%–99.6% and 69.2%–98.9%, respectively, at significant or extremely significant level. The traits were largely controlled by additive effects, little by environmental factors, and only effective for early generation selection in breeding practice. The growth period, plant height, spikelet length, pikelet width, and spikelet length-width ratio of most combinations displayed a heterosis of both negative intermediate and super parent hybrid vigor. The growth period of the hybrids was shortened, the plant height reduced, and the spikelet length-width ratio in between two parents. The growth period was an independent genetic trait, while the plant height somewhat positively correlated with the grain shape.Conclusion In breeding Indica-Japonicahybrids, balancing the benefits gained on the growth period, plant height, grain shape, and other traits through heterosis needed be carefully considered.
