摘  要:
本文分析讨论了小麦优良品种和优异种质资源繁六及其姊妹系的选育过程和特点,对它作为种质资源的作用、意义和应用以及它的系谱及其与衍生种的相互关系,进行了深入的分析,指出繁六及其姊妹系的研制在育种理论、育种方法和实际操作诸方面均有重大突破,认为繁六及其姊妹系是四川麦区小麦品种演变过程中具有划时代意义的一个小麦新类型和最重要的亲本材料,由此衍生了绵阳11号等29个小麦优良品种,栽种面积累计达2亿多亩,是四川麦区小麦生产过去二十年中连续上了两个台阶的重要因素,表明了种质资源创新和育种前基础理论研究的重大意义。

摘  要:
Fan—6 and its sisters, as the excellent wheat germplasms with the characters of high yield, early maturity, short growing period and strong resistaance to stripe rust, have been playing the greatiest role at wheat bleeding and production in Sichuan wheat ecological region for more than 20 years. This paper deals with its breeding process cross method and the relationship among Fan—6 and its sisters and the cultivars derived from them. The result shows that no better cultivars can be improved unless new breeding materials have been made. So, a great attention must be paid to the studying of the germplasms and theoretical research.
