摘要
胜A是以优质长粒型中9B为母本与丝苗型胜泰1号杂交,通过定向系统选育至F4代,从中选取优良单株与印水型三系不育系中100A杂交,之后再经过多代回交转育而成的优质籼型不育系。该不育系具有米质优、株叶形态好、败育彻底、育性稳定、柱头外露率高、异交习性好、配合力好等优点,于2015年通过广东省农业厅组织的不育系鉴定。以胜A为母本组配出的胜优青占、胜优美占等多个组合已通过广东省品种审定。
Sheng A, derived from the cross of long-grain Zhong 9B as the female parent and Simiao-type Shengtai 1 and the testcross of its F4 plants to Yinshui-type CMS line Zhong 100A followed by successive backcrossing for multiple generations, is a high-quality indica CMS line in rice. It has the advantages of excellent grain quality, good plant type,complete and stable fertility, high stigma exsertion rate, good outcrossing habits and good combining ability. It was technically identified by the Department of Agriculture of Guangdong Province in 2015. Several hybrid combinations derived from Sheng A such as Shengyou Qingzhan and Shengyou Meizhan have been registered and released in Guangdong Province.
