摘要
以果桑为材料,对其进行组织培养,利用RAPD技术对10次继代材料进行分析和聚类,它们的遗传距离在0.001～0.243,平均值为0.122。研究结果表明,继代次数越多,各代之间的遗传差异越大,且各个群间己经产生了遗传变异。
Tissue culture of fruit mulberry was studied. Plant materials of 10 times subculture were analyzed and clustered by RAPD. Among them, the genetic distance was between 0.001 and 0.243, and the average value was 0.122. Results showed that the more times of subculture, the bigger genetic differences in every generation. And genetic variation appeared in every cluster.
