摘　　要：对30个不同根形萝卜品种进行了游离小孢子培养研究。结果表明:在本试验所用培养体系下,近圆球根形萝卜品种的出胚基因型范围及出胚率均高于长圆筒根形品种。因此,对不同根形萝卜品种进行游离小孢子培养时,应采用其适宜的培养体系,以提高出胚率。In this paper, 30 radish varieties with different root shapes were used to conduct isolated microspore culture. The re- suits showed that： in the used culture system, the embryogenesis genotype scope and embryogenesis rate of radish varieties with nearly round roots were higher than those of radish varieties with long cylindrical roots. Therefore, in the isolated microspore culture of radish varieties with different root shapes, .the suitable culture system should be adopted in order to enhance the rate of embryogenesis.
