为优化淮河以南地区杂交水稻品种种植布局，选择9个杂交稻品种进行试验，通过对其品种特性与环境适应性分析，以筛选出适宜当地生产的高产优质品种。结果表明：苗情方面，荃优458移栽初期茎蘖数高，C两优198分蘖盛期茎蘖数突出，8两优徽香成穗数相对较高且齐穗较早；倒伏情况显示，C两优1598和深两优136有一定抗倒伏性，吨两优900抗倒伏表现较好；考种结果表明，理论产量荃优607最高，实收产量C两优1598最高；深两优136出米率最高，C两优1598和深两优136垩白率较低。综上所述，荃优607、C两优1598、Y两优911总体表现较好。

In order to optimize the planting layout of rice varieties in Huainan area, 9 hybrid rice varieties were selected for hybrid rice screening test to select high-yield and high-quality varieties suitable for the region through the analysis of variety characteristics and environmental adaptability. The results showed that the number of tillers of Quanyou 458 was high at the early stage of transplanting,the number of tillers of C Liangyou 198 was prominent at the tillering stage, and the number of panicles of 8 Liangyou Huixiang was relatively high and the full panicle was earlier. The lodging situation showed that C Liangyou 1598 and Shenliangyou 136 had certain lodging resistance, and Dunliangyou 900 had better lodging resistance. The trait analysis results showed that the theoretical yield of Quanyou 607 was the highest, and the actual yield of C Liangyou 1598 was the highest. The rice rate of Shenliangyou 136 was the highest, and the chalkiness rate of C Liangyou 1598 and Shenliangyou 136 was lower. In summary, Quanyou 607, C Liangyou 1598 and Y Liangyou 911 performed better overall.
