摘　　要：品种鉴定是品种保护和利用的基础工作,利用植物形态标记和SSR分子标记对大豆品种科丰14及其突变系北农106、北农107和北农108进行了鉴定方法的研究。结果表明,科丰14、北农106、北农107和北农108可以通过成熟期的持绿性、种皮及子叶色、花和种脐色等形态标记来鉴别;科丰14、北农106、北农107和北农108分别具有7、3、2和2个SSR特异标记可作为鉴定的分子标记。分子标记的多态性还表明,科丰14突变系的产生是科丰14多条染色体的多个区段发生变异的结果。Identification of variety is the basic work of the variety protection and utilization.The plant morphological markers and SSR markers were used to identify Kefeng 14 and its mutant lines in soybean,BN 106,BN 107 and BN 108,in this paper.The results showed that Kefeng 14,BN 106,BN107 and BN 108 were identified by morphological markers of the stay green in maturity,seed coat and green cotyledon color,flower and hilum color respectively.Kefeng 14,BN 106,BN 107 and BN 108 were identified by seven,three,two and two specific SSR markers as molecular markers of each species,respectively.The polymorphism of molecular markers also indicated that Kefeng 14 mutant lines were the result of a mutation for multiple segments in Kefeng 14 chromosomes.
