-
摘要: 选用明恢198、明恢185等5个含有粳稻血缘的偏籼型早熟恢复系与齐丰A、M10S等5个籼型三系和两系不育系, 按5×5不完全双列杂交试验设计 (NC-Ⅱ) 分析方法, 研究分析7个主要农艺性状的配合力。结果表明: (1) 7个主要农艺性状的一般配合力基因型方差占总方差的比重均高于50%, 这表明基因的加性效应对主要农艺性状的形成起主导作用。 (2) 偏籼型早熟恢复系对株高和单株产量的形成贡献较大。 (3) R1 (明恢198) 和R3 (明恢2155) 性状的一般配合力和特殊配合力较高, 表明偏籼型早熟恢复系明恢198和明恢2155具有较高的利用价值。 (4) 亲本的一般配合力和组合的特殊配合力之间不存在特定的对应关系。Abstract: The crosses were made from five early indica-deviation restorer lines derived from indica-japonica cross, including Minghui 198, Minghui 185 and three indica three-line sterile lines and two-line sterile lines, including Qifeng A, M10 Sto understand their combining abilities on seven mainly agronomic traits, respectively.A 5×5incomplete diallele cross (NC-Ⅱ) design was employed.The results showed that, (1) the genotype variances of the general combining ability (GCA) of seven mainly agronomic traits were accounted for more than 50%of the total variance, indicating that the gene additive effect played a leading role in the formation of mainly agronomic traits. (2) indica-deviation rice early restorer line took a great contribution to the formation of plant height and yield. (3) The general combining ability and the special combining ability were both higher on the characteristics of R1 (Minghui 198) and R3 (Minghui 2155) , showed that indica-deviation rice early restorer Minghui 198 and Minghui2155had higher value. (4) The combination of general combining ability and special combining ability of the parents did not exist close certain corresponding relationship.
