| 摘 要： | 选用低温敏水稻核不育系SE152S为改良主体亲本,通过杂交、回交,并将低世代分离群体置于高海拔长日低温(沙县湖源乡)生态环境分离筛选不育起点温度低的不育株,经海南加代繁殖穿梭育种,育成不育性稳定的闽科104S,本文就该不育系的选育过程进行探讨。

| Abstract: | A procedure for the development of a male sterile rice,Minke 104S,was established.The low-temperature-sensitive,genic sterile SE152S was used as the main parents.The lower generations of the segregated population obtained through crossing and backcrossing were planted in high altitude Huyuan Village in Shaxian County,where the average day-length was long and temperature low.The sterile lines were generation-added in Hainan Province and Shaxian County to obtain Minke104S with stable infertility.The breeding ... |
