对１９８６－１９９５年广西杂交水稻区域试验的５１个组合进行产量、穗状、米质等方面的分析表明，汕优桂９９、博优桂９９（９０３）、博优６４、枝优桂９９等杂交稻组合产量高、适应性广、抗性好、米质中至优。这些组合应用于大面积生产，实现了我区杂交水稻组合的早、中、迟熟组合配套和早、晚稻组合配套，为我区杂交稻发展做出了巨大贡献，但在特优质组合的选育上，产量、抗性欠佳，今后要注意米质、产量和抗性的综合性状选育。
Analysis on the yield, spike and grain quality of 51 combinations of Guangxi hybrid rice regional trial in 1986-1995 showed that the yield of the rice in Shanyougui 99, Bo Yougui 99 (903), Bo You 64, Zhi You Gui 99 Hybrid rice combination of high yield, wide adaptability, resistance, good quality rice. These combinations are applied to large-scale production, achieving early, middle and late maturity combinations and early and late rice combinations of hybrid rice combinations in our region, which made a great contribution to the development of hybrid rice in our region. However, Education, yield, resistance is poor, the future should pay attention to the quality of rice, yield and resistance of the traits of breeding.
