摘　　要：用两个性状互补的保持系D2 97B和花 1B进行杂交 ,育成了具有品质优、不育性稳定、柱头外露率高、异交率高、配合力强等优良综合性状的三系不育系T2 9A ,于 2 0 0 3年 9月通过福建科技厅鉴定。该不育系在 12项稻米品质指标中有 11项达到部颁二级米以上标准。A new CMS line of indica rice, T29A, was developed from a cross between two maintaining lines, D297B and Hua 1B, which are mutually complementary in many traits. The CMS line possesses elite comprehensive characters such as good quality, stable sterility, high stigma exertion rate, high outcrossing rate and high combining ability. The CMS line has passed the technical appraisal of the Science and Technology Department of Fujian Province in September 2003. Eleven out of the twelve indexes of rice quality of the CMS line reach or overpass the criteria of second-class rice decreed by the Ministry of Agriculture.
