| 摘 要： | 为建立一个高效的大豆再生体系用于大豆的遗传转化,选用3个东北主栽品种‘黑农35’、‘黑农41’和‘黑农58’的子叶节和胚尖作为外植体,分别建立了3个品种的子叶节和胚尖再生体系,并研究了6-BA对大豆再生的影响。结果表明,‘黑农41’子叶节最适芽诱导培养基为MSB5＋1.0mg·L-16-BA＋0.2mg·L-1IBA,胚尖最适芽诱导培养基为MSB5＋0.2mg·L-16-BA＋0.2mg·L-1IBA。‘黑农41’再生体系在出芽率、出芽数和芽伸长数上均远高于‘黑农35’和‘黑农58’,是一个优秀的大豆转基因受体材料。

| Abstract: | To establish a high frequency regeneration system for the gene transformation of soybean [Glycine max （L.） Merr.],cotyledonary nodes and embryonic tips from three varieties ＇Heinong 35＇,＇Heinong 41＇ and ＇Heinong 58＇ were used as the explants. Regeneration systems of cotyledon nodes and embryonic tips from three varieties were established in this research. Effect of 6-benzylaminopurine （6-BA） on soybean regeneration was studied. The results indicated that the optimal shooting induction medium of cotyledonary node from ＇Heinong 41＇ was MSB5 added 1.0 mg·L-1 6-BA and 0.2 mg·L-1 indolebutyric acid （IBA） and the optimal shooting induction medium of embryonic tip from ＇Heinong 41＇ was MSB5 added 0.2 mg·L-1 6-BA and 0.2 mg·L-1 IBA. In comparison with ＇Heinong 35＇ and ＇Heinong 58＇ regeneration systems,＇Heinong 41＇ regeneration system was superior in shoot regeneration frequency,shoot regeneration number and shoot elongation number. ＇Heinong 41＇ was an excellent receptor material in soybeans genetical transformation. |
