| Abstract: | Experement of Male—-Gametocide No.2 to rice in different consistency,varieties,andgrowth stages showed:(1)Killing male effection to indica,japonica and intermediate type was similar.The va-rieties in which male could he killed widespreadly existed.(2)Effecting period of Male-Gametocide No.2 to rice was longer.(3)The best effection of killing male could be obtained with 0.05% male-Gameto-cide in local production condition. |
