摘　　要：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。Genotype is one of＇ the important factors influencing soybean somatic embryo induction and plant regeneration. Forty one spring soybean cuhivars were researched to screen the ideal genotype for somatic embryo induction. The frequencies of soy- bean somatic embryo was different among tested materials, Kenfeng 23 （99.7%） was the highest; nine genotypes, including Hefeng 55, ranged from seventy to ninety percent; five genotypes, including Dengke 4, had no somatic embryos. The somatic embryos of Kenfeng 23 were grape-like and in bright green color. Kenfeng 23, with great number of somatic embryo on each im- mature cotyledon,did not produce deformity embryos, furthermore, each somatic embryo existed independently. For the other high inductivity cultivars, the somatic embryos number of each immature cotyledon was less than Kenfeng 23, and some culti- vars had deformity embryos.
