通过对国内外小麦早熟品种在云南利用情况及云南省育成品种的系谱分析表明：（１）在过去近３０年中，云南省小麦育种的中心亲本为Ｍｅｎｔａｎａ、Ｆｕｎｏ、Ｍｅｘｉｐａｋ６５、Ｍｅｘｉｐａｋ６６、ＮＰ７９８及Ｃｈａｐｉｎｇｏ等５个品种。（２）由于中心亲本的时间性，８０年代初期云南的中心亲本仅有Ｍｅｘｉｐａｋ６５、Ｃｈａｐｉｎｇｏ、Ｍｅｘｉｐａｋ６６等３个品种。（３）尽快发掘新的育种中心亲本是云南小麦生产及育种上新台阶的关键 The results showed that: (1) In the past 30 years, the central parents of wheat breeding in Yunnan Province were Mentana, Funo, Mexipak65, Mexipak66, NP798 and Chapingo 5 varieties. (2) Due to the temporal nature of the center parents, there were only 3 varieties of Mexipak65, Chapingo and Mexipak66 in Yunnan’s central parents in the early 1980s. (3) As soon as possible to explore the new breeding center parents is the key to Yunnan wheat production and breeding to a new level
