生姜属根茎植物，因其多种用途而具有特殊意义。此前，我们报道了水稻微卫星标记引物对作为 RAPD 的额外用途和适用性，用于姜科不同类群代表性种质的多样性评估。目前的研究旨在调查基因库、小规模自给农场和商业市场中的 Z. officinale 的遗传结构，以及三个 Zingiber 物种的遗传关系。观察到种质间在种间水平上的差异，并且物种特异性条带的扩增导致高度多态性。三个收集来源都表现出了 Z. officinale 的遗传变异性；然而，来自每个来源的一些种质倾向于聚集。 AMOVA 还显示了三个收集来源之间的显着差异，并解释了收集来源内的大部分差异 (87%)。一般来说，与来自基因库和市场的农场相比，当地小规模农场的铁皮植物表现出更高的遗传变异性。比较评估显示，与其他亚洲国家相比，缅甸生姜具有较高的等位基因多样性。生姜物种的遗传资源，特别是农场中提供的遗传资源，可以成为捕捉和利用多样性以进行保护以及进一步改良生姜的有用来源。
The Zingiber species comprises rhizomatous plants with special significance due to their multiple uses. Previously, we reported the additional use and suitability of primer pairs of rice microsatellite markers as RAPDs for diversity assessment in representative accessions of diverse taxa in the family Zingiberaceae. The current study aimed to investigate the genetic structure of Z. officinale at a genebank, small-scale subsistent farms and commercial markets, and the genetic relationships of three Zingiber species. A difference among accessions at the inter-specific level was observed and amplification of species-specific bands led to high polymorphism. Genetic variability in Z. officinale was exhibited by the three collection sources; however, some of the accessions from each source tended to cluster. AMOVA also displayed significant divergence among the three collection sources and explained most of the variance (87%) within the collection sources. In general, small-scale local farms displayed higher genetic variability in Z. officinale compared to those from the genebank and markets. Comparative assessment displayed high allelic diversity in ginger from Myanmar as compared to other Asian countries. Genetic resources of Zingiber species, particularly available on farms, can be a useful source to capture and utilize diversity for conservation as well as further improvement in gingers.
