| Abstract: | Indicia rice sterile line, 351A, was bred by AAAS. The character of 351A was the stability of fertility, good quality of rice grain, early maturation, resistant to bacterial leaf blight, high rate of outer stigma and strong combining ability. A set of sound technique of seed multiplication with high yield had been obtained through several years practice. The yield of seed multiplication was as high as 3.375 t/hm2 and the highest yield was 4.05t/hm2 in 1997～1999, which included the reasonable arrangement of flowering period, the control of seedling age, sparsely and early transplanting and much more fertilizer and so on. |
