摘　　要：通过对中9A/R12、中9A/R37、金23A/R8、株S/R36杂交早稻新组合及对照品种金优463进行比较试验,分别对参试组合的出叶速度、分蘖动态、产量构成因子及产量和农艺性状的表现进行比较分析。结果表明,中9A/R37产量为7231.5kg/hm2,在所有参试组合中产量最高,比对照增产4.80%,其综合性状表现良好,具有高产潜力,可在广西桂中、桂北地区大面积试种。Combinations of early hybrid rice Zhong 9A/R12,Zhong 9A/R37, Jin 23A/R8, Zhu S/R36 and Jinyou 463 （CK） were used in the comparison test.Leaf shooting speed, tiller dynamics, yield components, yield and agronomic traits were analyzed.The results showed that the combination 9A/ R37 had the highest yield of 7 231.5 kg/hm^2, 4.80% higher than CK.It had a good comprehensive performance with high yield potential, and could be demonstrated in larger area in central and northern region of Guangxi province.
