摘　　要：4个优质杂交水稻组合的比较试验结果表明,新品种贵香优1号、贵香优3号比对照内香优3号分别增产10.4%和2.5%,与对照II优838产量相当,贵香优1号、贵香优3号对稻瘟病的抗性水平达中抗,产量、抗病性综合性状表现较好的组合为贵香优1号,其每穗粒数为182.24±23.35,明显高于其他组合,且差异达到极显著水平,适宜在湖南西部地区作一季中稻种植。Results of comparison experiment with 4 hybrid aroma rice combinations showed that the new combinations Guixiang-you No.1 and Gui-xiang-you No.3 yielded 10.4% and 2.5% higher than Nei-xiang-you No.3 （CKI） respectively, and had almost the same yield level with II-you 838（CK2）. These two new combinations showed medium resistance to rice blast. The number of grains per spike of Gui-xiang-you No.1 was 182.24±23.35, very significantly higher than other combinations. Gui-xiang-you No.1 was the best among the 4 combinations and good for cultivation in western Hunan as middle-season rice.
