摘要: 为筛选较易再生的菜用大豆品种,为遗传转化建立良好的再生体系,以‘春丰早’、‘浙农6号’、‘浙农8号’、‘沪宁95-1’、‘辽鲜1号’和‘台湾75’为材料,研究外植体类型、激素配比、接种时间、接种方式以及基因型对再生频率的影响。结果表明:不同外植体类型中,子叶—子叶柄的再生频率最高;B5培养基+10 mg·L-1 TDZ+005 mg·L-1 NAA+50 mg·L-1 AgNO3为最佳培养基;种子发芽10 d为最佳接种时间;子叶—子叶柄垂直接种时再生频率较高;不同品种中,‘浙农8号’再生频率最高,达8089%;最佳生根培养基为1/2 B5+05 mg·L-1 NAA。

Abstract: To select the easily regenerating variety and set up a better regeneration system for transgenic work, effects of explant type, hormone concentration, inoculation time, inoculation method and genotype on shoot regeneration were studied based on six varieties of vegetable soybean, including Chunfengzao, Zhenong No.6, Zhenong No.8, Huning 95-1, Liaoxian No.1 and Taiwan 75. The results showed that the regeneration frequency of cotyledon\|cotyledon petiole was the highest among different explant types. The best medium of inducing adventitious buds was B5+05 mg·L-1 TDZ+005 mg·L-1 NAA+50 mg·L-1 AgNO3. The best inoculation time was 10 days after seed germination. Cotyledon-cotyledon petiole vertical insertion showed higher regeneration frequency than horizontal insertion. Regeneration frequency of Zhenong No.8 was the highest among six varieties, which reached 8089%. And the best medium of rooting was 1/2 B5+05 mg·L-1 NAA.
