摘要
宁A是用美B与特籼占13经航天搭载诱变获得的稳定突变株系H368杂交,再与美B回交1次后连续自交育成新的保持系,然后与美A测交并连续回交转育而成的水稻籼型不育系。具有群体农艺性状稳定、茎秆较粗壮、分蘖力强、败育彻底、育性稳定、米质优、稻瘟病抗性好、开花习性好、配合力强等特点,2013年10月通过广东省田间技术鉴定。所配组合宁优1179(宁A/R1179)于2014年通过广东省品种审定。
Ning A,developed from the testcross of Mei A to the B1F4 lines selected from Mei B /H368（a space mutation line of Texianzhan 13）∥Mei B and its successive backcrosses,is a new indica CMS line in rice. It is characteristic of a stable population in agronomic traits,thick stature,strong tillering ability,complete and stable male sterility,fine grain quality,good blast resistance,good flowering habits and high combining ability. In October,2013,it was technically identified in Guangdong Province,and its hybrid Ningyou 1179（Ning A /R1179） was registered and released to commercial production by Guangdong Provincial Crop Variety Appraisal Committee in 2014.
