在对具有雄性不育强恢复基因的新恢复材料进行测配、筛选中 ,不仅显示出通过种间、亚种间杂交选育新恢复材料已经取得实质性进展 ,尤其发现并筛选出诸如“R418”“R42 6”等一批极具高产、早熟潜力 ,更适于组配适合高海拔低气温生态条件的早中熟杂交稻组合的重点恢复材料
In the test of new restorer materials with strong restorer genes of male sterility, screening not only shows that substantial progress has been made in breeding new restorer materials through interspecific and inter-subspecific hybridization, in particular, it has been found and screened that “R418 ”R42 6" and a number of very high yield, precocious potential, more suitable for the combination with high altitude and low temperature ecological conditions of early maturing hybrid rice combination of key recovery materials
