选用2个水稻品种和6个陆稻品种进行双列杂交,对各主要产量性状进行配合力及杂种优势分析.结果表明:各品种农艺性状的一般配合力表现差异较大,各杂交组合农艺性状的特殊配合力表现差异也较大.杂种优势分析表明:陆稻品种之间杂交有不同的杂种优势表现,水、陆稻杂交也能够获得较高的超亲优势和平均优势.说明陆稻可以作为改良水稻品种产量或个别农艺性状的资源加以利用.水稻品种也可以在陆稻品种产量或个别产量性状改良中发挥重要的作用.
Two rice cultivars and six Upland rice cultivars were selected for double crosses to analyze the combining ability and heterosis of the main yield traits.The results showed that the general combining ability of agronomic traits of each cultivar was quite different and the agronomic traits The heterosis showed a great difference.The heterosis analysis showed that heterosis was observed in the cross between Upland rice varieties and the heterosis and the average superiority in cross between Upland and Upland rice were higher Is used as a resource to improve rice yield or individual agronomic traits, and rice varieties can also play an important role in improving the yield or individual yield traits of upland rice.
