Abstract:

Being an unique crop breeding method firstly initiated by China, “Nan Fan” has made special contributions to crop breeding for shortening breeding process, and accelerating generation reproduction. So far, about 80% of over 5 000 varieties all over the country have been bred by  “Nan Fan” crop breeding method. On the basis of summing up present status of “Nan Fan”, in order to take advantages of “Nan Fan” to speed up the cultivation of new crop varieties, and to promote stable development of grain and agriculture production, this paper analyzed the existing problems limiting its development  in planning, management, infrastructure construction and land use conflicts for “Nan Fan”. It also put forward recommendations accordingly.

摘要：

“南繁”作为我国首创的一种独特育种方式,在农作物品种培育过程中发挥着缩短育种年限,加速世代繁育的特殊作用。目前,在全国推广的5 000多个农作物品种中,约有80%经过了“南繁”的选育或者加代。在总结“南繁”现状的基础上,从充分利用"南繁"这一优势,加快优良农作物新品种的培育,促进粮食生产和农业稳定发展的角度,分析了在“南繁”中存在的规划、管理、基础设施建设和用地矛盾等制约其发展的几个问题,并提出了相应的建议。
