| 摘 要： | 试验研究了8个甘草(Glycyrrhiza uralensis)不同品系种子的特征、特性及其遗传多样性。结果表明:甘草不同品系间在种子大小、发芽率、发芽势等方面存在显著差异(P<0.05)。进一步利用ISSR标记对甘草8个品系的遗传多样性进行分析,发现甘草不同品系间存在明显的遗传多样性差异,共扩增出42条不同的产物,其中多态性片段34条(占80.95%),并发现了2条特异性带。通过计算遗传相似性系数,建立了UPGMA聚类图。

| Abstract: | Seed properties and genetic diversity among different lines of Glycyrrhiza uralensis were studied.The results showed that shape and germinating rate were different among 8 lines.Genetic diversity among 8 lines was investigated with ISSR technique.Amplified results showed a total record of 42 bands,among which 34(80.95%) were polymorphic.By calculating genetic similarity coefficient,UPGMA clustering map was made.ISSR is valuable to breeding selection for Glycyrrhiza uralensis |
