| 摘要: |
| 根据几年来的实地考察和形态、生态、生理生化以及杂交亲和力等方面的综合研究可以确定,云南光壳稻在栽培稻分类上属粳稻,而是原始的、尚未分化彻底的粳稻类型,它与整个东南亚、南亚以及美洲的光壳稻属于亲缘关系很近的同一粳稻类型;它的大粒、耐旱、耐寒、耐阴雨、耐病以及优质米等类型是稻作育种上十分宝贵的种质。作者还提出了亚洲栽培稻演化途径的设想。 |

| Abstract: |
| On the basis of comprehensive study of morphology,physiologybi- ochemistry,ecology and hybrid fertility test the authors recognized that the nuda in Yunan belongs to O.s.subsp,keng(japonica),but more originary keng without clear differentiation.There is close rela- tionship between Yunan nuda and the glaberous rice in Southeast,So- uth Asia and in America.The authors suggested a scheme of the evo- lutionary pathway from wild to cultivated rice forms. The nuda in Yunan is very valuable germplasm with their b... |
