| 摘 要： | 以太谷核不育基因为桥梁选用有关亲本组配了6个春小麦轮回选择集团,经轮选过一轮后,从中选择150个优良可育株,进行花药培养,其平均花药出愈率为22.09%,绿苗诱导率9.22%,均高于同年及上年度品种间杂交 F_1的花药培养结果。白苗分化率21.93%,与上述两年的 F_1培养结果相近。说明不育基因对花药培养无不良影响。加倍花粉植株二代 |

| Abstract: | Several related parents were crossed with a bridge parent containingthe Tai-Gu dominant male-sterile gene to produce six recurrent selectiongroups of spring wheat,and the anthers of 150 fertile Plants from therecurrent selection groups were cultured.The mean induction frequencyof pollen callus(22.09%)and that of green plantlet(9.22%) were higher than those cultured from the anthers of the intervarietal hybrid F_1crossed in the year before,but there was no significant difference in thealbino seedling differentiation frequency(21.93%).The results showedthat the male-sterile gene did not have bad effect on anther culture.The H_2 pollen plants with doubled chromosomes grew normally in thefield. Growth duration,plant height and spike characters were differentsignificantly among the strains within the same group but not differentwithin the same strain.A few winter strains were separated.Sevenhopeful strains were selected,and these strains could be propagated intee fall.The breebing cycle was shortened significantly. |
