以10个品种为材料，在湖南浏阳烟区开展烟后晚稻适宜品种筛选研究，结果表明：(1)供试品种产量差异显著，在7130~9938 kg/hm2之间；(2)供试品种全生育期差异显著，在115~132 d之间，从安全齐穗考虑，烟后水稻全生育期应在125 d之内；(3)本试验条件下，适合作烟后晚稻种植的品种有两类：一类是生育期短(115 d左右)、分蘖能力较强、穗型中等(150粒左右)的品种，如深优9588；一类是生育期居中(120~125 d)、分蘖能力一般、穗型较大(200粒以上)、千粒重较大(27 g左右)的品种，如T优272。

A screening study on suitable variety of late rice after tobacco harvesting was conducted with 10 varieties as mate-rials in tobacco area of Liuyang, Changsha, Hunan. The results showed that:(1) Yields of tested varieties ranged in 7 130~9 938 kg/hm2 , and significant difference existed among them. (2) Growth duration of tested varieties ranged in 115~132 days, and significant difference existed among them. Considered from safety full heading, the whole duration should be shor-ter than 125 days. (3) In this study, there were two types of varieties suitable to be planted as late rice after tobacco. One type of varieties had shorter growth duration ( about 115 days) , stronger tillering ability and medium panicle type ( about 150 grains per panicle), such as Shenyou 9588. Another type of varieties had medium growth duration (120~125 days), com-mon tillering ability, larger panicle type ( above 200 grains per panicle) and bigger 1000-grain weight ( about 27 g) , such as T You 272.
