| Abstract: | The male sterile line"Zhensan 97A" back crossed continuously 18 generations by descendant plant of Zhensan 97"crossed"Ganjizhan".So,the male sterile line"Nong A"which used as indica hybrid rice was breeded.The "Nong A"have follows character:the plant height is about 83.7 cm.Days from sowing to heading is 75 d in early season and 67 d in late season.The leaves numbber are 14,grains/spike are 245.4.Weight of 1000 seeds is 23 g.The type of grain is long.Chaff of grain is light golden yellow,self-unfruitful.The degree of male pollen sterility is 99.99 percent. The rate of exogenous style is about 75%.flowering angle is big.Rate of cross is high.Yield is high in reproduction and breeding.Conbining ability of yield and factor of yield constitute are good. |
