| 摘 要： | 以强耐冷异种质资源－－东乡野生稻为骨干亲本,采用“双重”低温加压筛选法对粳稻耐冷性进行遗入良,取得了良好效果,育成的4913－1粳稻品种（品系）其耐冷水平,在苗期（二叶一心）冰箱0℃处理48h,完好无损,在南昌自然条件下越冬再生3年,通过生产示范,产量,品质和抗性都得到了较理想的效果。并且育成了粳型三系不育系和两用系不育系,可以在南昌越冬,可望实现杂种优势固定大面积应用于生产。

| Abstract: | In this study, Dongxiang wild rice was used as the parent material to develop new rice variety with cold tolerance. A new line named "4913-1"was bred successfully by two-step low temperature treatment.This new line has stronger tolerance to clod, So it can regenerate as the regenerating rice several times by vegetable propagation, and its rice, quality and stress-resistance are also good. |
