摘要/Abstract

摘要： 对中国种诸葛菜变种群（色括原变种及三个变种）作了大样本核型分析，结果显示：染色体相对长度从长到短呈渐缓梯度变化，次缢痕位置大多出现在第11对染色体上，一部分次缢痕变化不定。臂比指数极端变幅大，按众数求得的染色体类型是：2n=24(2st)+6sm(2st)。核型对称性分析结果是1A-2A，属于最对称性。核中有较高频率的B染色

关键词: 中国种诸葛菜，核型

Abstract: A study on the karyotype of some Chinese variants of Zhuge Cai, Orychophragmus violaceus, was carried out with the following results: Relative length of chromosomes showed a gradual gradient form long to shout, the gaps among them being very small. The majority of secondary constrictions in 30 cell

Key words: Chinese Zhuge Cai, Orychophragmus violaceus, Karyotype analysis
