为了快速培育小麦新品种,我们于1974年试搞小麦花粉培养,前后获得了花培88小麦和花培157小麦二个新品系,现将花培157小麦新品系试种情况总结如下:(一)选育过程1976年利用扬麦一号×68—6143F_5的杂种花粉进行离体培养,获得了单倍体植株,用0.4％的秋水仙素处理人工加倍方法,收到了第一代种子。
In order to quickly cultivate new varieties of wheat, we conducted wheat pollen culture in 1974, before and after obtaining two new lines of flower-cultivating wheat 88 and flower cultivating 157 wheat. Now we summarize the trial of new varieties of flower cultivating 157 wheat as follows: ) Breeding process In 1976, Yangmai × 68-6143F_5 hybrid pollen was used for in vitro culture. The haploid plants were obtained. The first generation of seeds was harvested with 0.4% colchicines by artificial doubling method.
