根据我国育种者种子及良种繁育工作的现状 ,借鉴农业发达国家禾谷类作物种子生产方法和我国良种繁育的先进技术 ,结合我场多年来小麦种子的生产实践 ,将循环选择技术路线与重复繁殖技术路线有机地结合在一起 ,研究总结出一圃三级小麦种子生产技术。该技术可使小麦种子的生产周期缩短两年 ,解决了我国现阶段育种者种子在小麦良种繁育中存在的问题 ,具有省工、省时、提高繁殖系数、易于操作的优点 ,并可保持优良品种的典型性和纯度 ,有利于促进小麦新品种的推广和持久地在生产上应用
According to the status quo of seed breeder breeding and seed breeding in our country, drawing on the methods of seed production of cereal crops in advanced agricultural countries and the advanced technology of seed breeding in our country, combining the practice of wheat seed production in our field for many years, The route organically combines together to study and summarize a three-level wheat seed production technology. The technology can shorten the production cycle of wheat seeds by two years, and solve the problems that the seed of breeders in wheat breeding at present stage in our country have the advantages of saving labor, saving time, raising the breeding coefficient, being easy to operate, The typicality and purity of cultivars are conducive to promoting the promotion of new wheat varieties and their long-lasting application in production
