摘  要:通过对盐粳68/密阳50、盐粳68/盐粳34、盐粳68/一目惚3个不同类型水稻杂交组合F2群体产量性状表现及遗传参数估算,分析了水稻不同类型亲本杂种后代与亲本的关系。结果表明,产量性状的表现及其遗传参数因亲本类型的不同而有明显差异。籼、粳亚种间杂交组合F2群体产量性状变异幅度大、遗传力较高、遗传进度也较大,因而有广泛的选择潜力。An experiment was made to assess the yield performance of F2 generation offsprings from three types of crosses including Yanjing 68/ Milyang 50, Yanjing 68/Yanjing 34, and Yanjing 68/Hitomebore, to estimate inheritance parameters, and to analyze the relationships between offsprings and parents. The results showed that yield performance and inheritance parameters varied significantly in term of different parent. There existed wide yield variation range, high inheritance ability and great inheritance rate among F2 populations from cross of indica and japonica rice sub-species, therefore, these offsprings had a great selection potential.
