以41个北方春大豆品种为材料,研究了不同基因型大豆体细胞胚的诱导率。结果表明:不同基因型大豆的体细胞胚发生率有显著差异,在供试品种中,垦丰23的体细胞胚胎发生率(99.7%)最高,合丰55等9个基因型体细胞胚诱导率为70%～90%;登科4等5个基因型无体细胞胚发生。垦丰23体细胞胚呈葡萄状、颜色鲜绿、每个未成熟子叶上体细胞胚的数量较多、无畸形胚、且每个体细胞胚是独立存在的,其他诱导率较高的基因型每个未成熟子叶分化体细胞胚的数目较少,且部分基因型含有畸形胚。 In this study, 41 northern spring soybean cultivars were used as materials to study the induction rate of somatic embryos in different genotypes of soybean. The results showed that the somatic embryogenesis rates of different genotypes of soybean were significantly different. Among the tested cultivars, Kenfeng 23 had the highest somatic embryogenesis rate (99.7%), and Hefeng 55 and so on. Rate of 70% to 90%; Deng Ke 4 other 5 genotypes somatic embryogenesis. The somatic embryo of Kenfeng 23 was grapes with bright green color. The number of somatic embryos on each immature cotyledon was more and there was no deformity embryo, and each somatic embryo was independent. Other genotypes with higher inducibility The number of somatic embryos differentiated per immature cotyledon is small, and some genotypes contain abnormal embryos.
