摘　　要：During 2000-2013, totally ten high-amylose specific hybrid rice combinations approved and five combinations for production test were bred in Sichuan Province. In the paper, rice yield, economic traits, quality indicators and rice blast-resistance identification results of these 15 hybrid combinations were described and analyzed. Results show that Chuanxiangyou37 and Tianlongyou540 have relatively high amylose content, good yielding ability, high resistance and appropriate growth period, which are new hybrid rice varieties with organic combination of high amylase content, high gel consistency, high yield, stable yield and wide adaptability. Therefore, Chuanxiangyou37 and Tianlongyou540 are recommended as the main combination for rice production.2000～2013年四川省共育成了10个通过审定的高直链淀粉含量专用杂交稻组合,及5个参加生产试验的组合。文中介绍和分析了这15个组合的稻谷产量、经济性状、品质指标和抗稻瘟病鉴定结果,发现川香优37和天龙优540的AC较高、丰产性好、抗性较强、生育期适宜,是将高直链淀粉、高胶绸度、高产、稳产、广适有机结合的杂交稻新品种。因此建议选用川香优37、天龙优540作为专用稻米生产的主要组合。
