对绵农号小麦品种选育中后代处理方法的探讨

AN INQUIRY INTO THE IMPROVING METHODS ADOPTED IN THE WHEATVARIETAL SELECTION OF “MIANNONG”

通过对绵农号小麦品种选育工作的总结，浅析了“多组合、小群体”及“以穗代株选择法”等小麦常规育种后代处理方法。前者抓住了选组合这一主要矛盾，后者较好地综合了系谱法和混合法的优点，较好地提高了小麦育种效率。

Two improving methods i.e. “many crosses and small colony” and “ear selected instead of plant” have been adopted in the selection of generations. The first one is advantageous to the solution of the principal contradition in selecting cosses. The second one has advantages of systematic selection and mixed selection at the same time.
