摘要: 采用去壁低渗火焰干燥法制备小扁豆染色体标本观察其核型,结果表明,绿小扁豆和红小扁豆的核型公式均为2n=2x=16=6m+6sm+2st+2st(SAT),两种小扁豆的核型类型都是3B,染色体相对长度系数组成均为2n=2x=16=4L+6M2+6M1+4S,二者主要在第7号染色体臂比和2号染色体大小方面有明显差异。

关键词: 小扁豆, 染色体, 核型, 随体(SAT)

Abstract: Karyotype analysis of two varieties of Lens culinaris Medichas been studied by means of preparing mitotic chromosome specimen and Giemsa staining technique.The results obtained showed that theyhave the same formula of 2n=2x=16=6m+6sm+2st+2st(SAT). They allhave "3B" karyotype. Theyhave the same chromosome relative length coefficient of 2n=2x=16=4L+6M2+6M1+4S. The obvious difference on arm ratio of the seventh chromosome and length of the second chromosomehas been gained between the two varieties of Lens culinaris Medic.

Key words: Lens culinaris Medic, Chromosome, Karyotype, Satellite(SAT)
