| Abstract: | In this paper, the 5 Indica P(T)GMS rice lines of 3418S, X07S, 399S, 2301S and Peiai64S(CK) were used as the materials. The bagged self-seed and the abortive pollen of them were studied by sowing on different dates from 1994 to 2001 in Hefei. The results showed that the steadily completely sterile period of them was about from the tenth to the twenty-fifth of August for many years. Their corresponding stage of the safely sensitive sterile fertility was about from the twenty-fifth of July to the fourteenth of August. |
