| 摘 要： | 对104份不同基因型材料进行花药培养，结果表明：F1代愈伤组织诱导率为13.28%，高于F3代的6.02%; 绿苗产率F1代为2.88%，F3代为1.10%，F1相当于F3的2.6倍。同样的培养条件下，不同基因型材料间花药培养力差异很大，愈伤诱导率在 0～111.43% 之间、绿苗产率在 0～49.29% 之间；愈伤诱导率、绿苗分化率与绿苗产率三者之间成正相关关系。同时筛选出了一批如宁春4号等具有高培养力、高产和优质基因的花培桥梁亲本，为有目的配制杂交组合提供依据。

| Abstract: | Research on anther culture response （ACR） of different wheat genotypes and different hybrid generations will provide the basis for hybrid combinations,and improve the efficiency of anther culture breeding.104 genotypes of wheat anther were cultured by inducing medium,differentiation medium and seedling medium in order to evaluate the effects of genotypes on ACR.The results showed that the callus induction rate of F 1 hybrid generation was 13.28%,higher than 6.02% of the F 3 generation;the green plant production rate of F 1 was 2.88%,F 3 was 1.10%,F 1 was 2.6 times of F 3.Among the different genotypes,callus induction rate from 0% to 111.43%,green plant production rate from 0% to 49.29% when in the same culture conditions.According to the results,selected some varieties or genotypes with high-culture ability,high-yield and high-quality genes such as Ningchun 4 varieties.Correlation analysis showed that the callus induction rate,green plant regeneration rate and green plant yield were positively correlated. |
