粤优９３８为三系法杂交籼稻新组合。该组合米质优、产量高、综合抗性好。据农业部稻米质量验测中心检测，粤优９３８的精米率、粒长、长宽比、透明度、碱消值、胶稠度、蛋白质含量达优质米一级标准，糙米率、整精米率、垩白度、直链淀粉含量达优质米二级标准。粤优９３８在１９９７～１９９８年度江苏省杂交籼稻区域试验及同期进行的示范生产试验中，平均亩产６５０±５０ｋｇ，比汕优６３增产７５％±２０％。粤优９３８抗白叶枯病、稻瘟病，纹枯病轻，抗倒性较强。
Yueyou 938 is a new combination of three lines hybrid indica rice. The combination of high quality rice, high yield, good overall resistance. According to the Ministry of Agriculture rice quality testing center testing, Yueyou 938 milled rice rate, grain length, aspect ratio, transparency, alkali consumption, gel consistency, protein content of a high-quality rice standards, brown rice rate, milled rice rate, chalk Whiteness, amylose content of high quality rice secondary standard. Yueyou 938 showed that the average yield per mu was 650 ± 50kg and the yield was 75 ± 20% higher than that of Shanyou 63 in the regional experiment of hybrid indica rice in Jiangsu Province during 1997 ~ 1998 and the demonstration production experiment in the same period. Yueyou 938 is resistant to bacterial leaf blight, rice blast, light blight and lodging resistance.
