| 摘 要： | 用ISSR技术对30份魔芋种质资源进行了DNA多态性分析。从65个随机引物中筛选出11个扩增基因组DNA,共获116条带,其中102条为多态性标记,每个引物平均提供10.55个标记信息。UPMGA法聚类分析结果表明:这30份魔芋种质资源间的Jaccard相似系数都比较大,在0.65以上;甜魔芋和花魔芋以及西盟魔芋和珠芽魔芋的关系比较近;白魔芋的遗传多样性较为丰富,它与花魔芋的关系较近。

| Abstract: | The ISSR analysis was conducted in the 30 germplasm resources in Amorphophallus.Among 65 random primers,11 were selected for amplification of the 30 genomic DNAs.Total 116 RAPD fragments were generated,102 of them were polymorphic marks.Every primer offered 10.55 marker bands on average.The molecular phylogenetic tree obtained by UPMGA method showed that Jaccard similarity coefficient of the 30 germplasm resources is quit high,over 0.65. Genetic diversity in Amorphophallus albus is richer than that of others,and it is close to Amorphophallus konjac.Amorphophallus dunnii is close to Amorphophallus konjac,while Amorphophallus krausei is close to Amorphophallus guripingensis. |
