河南省小麦品种的血缘分析

The Consanguinity Analysis of Wheat Varieties in Henan Province

经对河南省近年推广的109个小麦主要品种的血缘组成进行分析,发现这些品种可归为阿夫、内乡5号、丰产号、阿勃、碧蚂麦、辉县红、玛拉、郑引4号、郑引1号、偃麦草、黑麦、洛夫林、高加索、山前麦、阿芙乐尔和其它亲本品种等16个亲本系统。分析还发现亲本系统的地理来源主要是意大利;来自国外的亲本以及我国的亲本品种仍具有一定的血缘关系;生产上利用品种大都具有相似的遗传构成。据此对小麦育种中亲本的选择、优良品种的审定和利用进行了讨论。

The consanguinity of the 109 wheat varieties cultivited in Henan Province in recent years had been analysed. The results indicated that these wheat varieties could be classfied into such 16 parent systems as Funo,Neixiang 5,Fengcan group,Abbondanza,Bimamai,Huixianhong,Mara, Zhengyin 4, Zhengyin 1, Elytrigia, Rye, Lovrin, Kavkaz, Predgovnaja 2, Aurora and other parent varieties etc. It was also found that most of the parent systems were primarily from Italy, the parents from abroad and domestic parents were also related,and many wheat varieties popularized were similar in genetic component Finally,in accoordance with the above results,the basis for the election, examination and utilization of parent varieties in wheat breeding was disscussed.
