摘要： 通过分期播种试验，对3个野败型新型水稻不育系华川4A、华J2A、华S40A的生育期、叶龄、柱头外露率、开花习性、农艺性状等进行了观察。结果表明：3个不育系在不育期内的育性稳定，可育期内不育系具有较高的结实率；3个不育系的生育期在60~70d左右，主茎叶片数为13~14片，张颖角度一般在30~40°之间，柱头外露率在39.1%~46.8%左右，花时较为集中，且农艺性状均比较稳定。

Abstract: The seeding experiments of 3 new-type wild sterile rice: Huachuan 4A, HuaJ2A and HuaS40A, were carried out by stages.And the bearing, leaf-age , the Exposing rate of stigma, habits and characteristics of blossoming ,and the agricultural properties were observed . The results indicate: 3 sterile rice have stable character in the sterile time, on the contrary, have fairly good bearing rate; and the bearing period is about 60~70d;the lades in the main stem is 13 or 14;the open angle of glume is 30~40°; the Exposing rate of stigma is 39.1%~46.8% or so; the blossoming time concentrated; and the agricultural properties are more steady.
