河南省近年利用的小麦品种的血缘分析

经对河南省近年推广的109个小麦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、碧玛麦、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;来自国外的亲本和我国的亲本品种还具有一定的血缘关系;生产上利用的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 Analysis of Wheat Varieties Cultivated in Henan Province in Recent Years
