栽培水稻微核心种质中BT型恢复基因Rf1a的检测

Detection of Restorer Gene Rf1aof BT Type in Cultivated Rice Mini-core Collection

为了拓宽水稻BT型细胞质恢复基因来源和进一步利用水稻微核心种质资源,利用前人开发的BT型恢复基因Rf1a的功能多态性标记,对198份栽培水稻微核心种质进行检测,共获得携带恢复基因Rf1a的材料143份,占微核心种质的72.2%,其中有16份为粳稻材料。

To broaden the source of restorer gene of BT type and utilize rice mini-core collection in further,the mini-core collection of 198 rice cultivars were detected by using functional polymorphism markers of restorer gene Rf1aof BT type developed by predecessors,and 143 materials were obtained carrying the restorer gene Rf1a,accounting for 72.2% of micro-core collections,in which 16materials were japonica rice.
