摘　　要：为探明适宜于南县双季晚稻生产的优质高产籼粳杂交稻品种,以当地双季晚稻主栽超级杂交稻H优518为对照,分析比较籼粳杂交晚稻品种甬优1540、春优84、甬优538、甬优9号、甬优12号等在南县地区的生育期、产量、抗性和经济效益。结果表明:供试籼粳杂交品种全生育期均长于对照,分别比对照增加12、9、6、20和12 d;水稻产量均高于对照,分别比对产增产6.4%、14.6%、11.3%、5.1%和11.9%;经济效益均明显高于对照,分别比对照增加21.5%、41.6%、33.5%、18.5%和35.1%。In order to explore the suitable varieties of Indica/Japonica hybrid rice in Nanxian, the growth stages, grain yield, resistance ability and economic benefit of some rice varieties were studied, such as Yongyou 1540, Chunyou 84, Yongyou 538, Yongyou 9 and Yongyou 12, by using H you 518 as control. The results showed that the whole growth stages of the rice varieties of Yongyou 1540, Chunyou 84, Yongyou 538, Yongyou 9 and Yongyou 12 were longer 12, 9, 6, 20 and 12 days, respectively, compared with the CK. Meanwhile, the grain yield of Yongyou 1540, Chunyou 84, Yongyou 538, Yongyou 9 and Yongyou 12 were increased by 6.4%, 14.6%, 11.3%, 5.1% and 11.9%, and their economic benefit were increased by 21.5%, 41.6%, 33.5%, 18.5% and 35.1%, respectively.
