绝大多数大麦的花培绿苗分化频率极低和供试基因型之间的花培绿苗率差异极大是阻碍花培技术运用于大麦品种改良的两大难题。我们经过多年研究,已使大麦花培绿苗分化效果得到明显改善,在1991年春季接种92个F_1种F_2代的55600枚花药中,获得了2291丛绿苗。供试的F_1和F_2代花培材料中,其绿苗分化率(绿苗数/接种花药数)达50％以上的有1个,达10％以上的有7个,达5％以上的有16个,达
The vast majority of barley flower culture green shoot differentiation frequency is extremely low and the tested genotypes between the flower green seedling rate is extremely different is hinder flower cultivation techniques applied to barley varieties to improve the two major problems. After years of research, we have significantly improved the differentiation effect of barley greenpea seedlings. In the spring of 1991, we got 2291 green seedlings of 55600 anthers from 92 F_1 F2 generations. The tested F_1 and F_2 generation of flower culture materials, the green seedling differentiation rate (number of green seedlings / number of inoculated anthers) of more than 50% of a, more than 10% of 7, more than 5% 16, up
