| Abstract: | Zhenpin A,derived from Zhenshan 97A/Zhenong 986(Zhenong 8010/Zhongxuan 16),is a new WA-type indica CMS line with early maturity in rice.It had stable agronomic characters and good plant type.Its rate of sterile plants was 100%;the rate of abortive pollens was 99.97%;the outcrossed seed setting rate was 45.5%;the stigma exsertion rate was 87.1% with 56.5% of double-stigma exsertion rate.It had good grain quality characters.It was highly resistant to rice blast.It also showed a good combining ability and restorable ability.In September,2004,it was technically identified and registered in Zhejiang Province. |
