摘要
通过国内外小麦早熟品种在云南的利用，及云南省育成品种的亲缘系谱分析表明：（１）在过去近３０年中，云南省小麦育种的中心亲本为Ｍｅｎｔａｎａ、Ｆｕｎｏ、Ｍｅｘｉ－ｐａｋ６５、Ｍｅｘｉｐａｋ６６、ＮＰ７９８及Ｃｈａｐｉｎｇｏ；（２）由于中心亲本的时效性，８０年代后期．云南的中心亲本仅Ｍｅｘｉｐａｋ６５、Ｍｅｘｉｐａｋ６６及Ｃｈａｐｉｎｇｏ三个品种；（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。
Analysis of pedigrees or affinities of Yunnan early maturing varieties from home and abroad was conducted. The results showed that:in the past 30 years,the staple parents used in breeding program were Mentana,Funa, Mexipak 65, Mexipak 66,NP798 and Chapingol however, in .late 11980's only Mexipak 66, Mexipak65 and Chapingo, were used as central parents. Because of their durabilities,exploiting new early maturing parents is the key to further improvement in wheat breedingand preduction.
