薯蓣植物的染色体数目与形态特征相关性分析

摘要

Chromosome number and morphologies of 20 germplasm accessions of Dioscorea spp. And 19 germplasm accessions of Dioscorea data L. Originating from south China were investigated and identified. There were rich morphologies and the chromosome number was 40 or 60, respectively. There were some relationships between . Chromosome number and morphologies.%对从中国南方地区搜集的20份山药和19份大薯种质材料进行了形态特征鉴定与染色体计数.结果显示,山药和大薯形态特征丰富,染色体数目为40条或60条,且形态特征与染色体数目存在相关性.
