| 摘 要： | 对中国云南德宏和曲靖、湖北恩施、江西怀玉山高山马铃薯种质资源的过氧化物酶(POD)、酯酶(EST)和多酚氧化酶(PPO)同工酶进行了分析研究,以期揭示其遗传多样性。结果表明,云南德宏高山马铃薯、云南曲靖高山马铃薯和湖北恩施高山马铃薯均属于同一类,遗传分化程度较低,而怀玉山高山马铃薯单独成一类;用块茎和叶片做同工酶检测,会造成结果的差异,因而应保证取材的一致性。该实验结果可为进一步开展高山马铃薯品种遗传改良、杂交亲本选配以及高山马铃薯种质资源的利用提供依据。

| Abstract: | The genetic diversity of alpine potato germplasm resources in Yunnan Dehong, Yunnan Qujing, Hubei Enshi and Jiangxi Huaiyushan was analyzed by peroxidase (POD), esterase (EST) and polyphenol oxidase (PPO) isozyme in this paper. The results showed that Yunnan Dehong alpine potato, Yunnan Qujing alpine potato and Hubei Enshi alpine potato belonged to the same type, and the degree of their genetic differentiation was low, while the alpine potato in Jiangxi Huaiyushan was a separate group. Isozyme analysis of tubers and leaves would result in the difference of results, and isozyme analysis should ensure the consistency of sampling. The results of this study can provide the basis for further genetic improvement of potato varieties, selection of hybrid parents and utilization of alpine potato germplasm resources. |
