摘要

引进13个感光型杂交稻新品种进行比较试验，结果表明元优6582、臻优70、元优2105、元优2108等4个品种丰产性好、生育期比CK迟熟在5d以内，可在南靖县大部分双季稻区进一步试验；益优3550、益优70、元优2106、广优制西、元优2112等5个品种生育期比CK长5～11d，只适宜在南靖县平原双季稻区试种。%13 photosensitive hybrid rice combinations were introduced and planted in Nanjing country. The results showed that Yuanyou 6582, Zhengyou 70 Yuanyou 2108 and Yuanyou 2105 had good agronomic characters compared with the controls. The growth period of Yiyou 3550 Yiyou 70 Yuanyou 2106 Guangyouzhixi and Yuanyou 2112 was longer than CK 5 ~ 11 d, and these combinations were suitable for cropping area in the plains of Nanjing county trials.
