滇红椿表型性状遗传多样性研究进展

Advances in Researches on Morphological Characters Genetic Diversity in Plants of Toona ciliata var.yunnanensis

  • 摘要: 滇红椿(Toona ciliata var.yunnanensis)是红椿(Toona ciliata)的一个变种,属楝科(Meliaceae)香椿属(Toona)植物。目前对滇红椿的种内遗传变异或多样性研究尚未有文献报道。本文在前人研究的基础上,通过对国内外香椿属植物表型性状遗传多样性研究进展的论述,总结了滇红椿在遗传多样性研究方面目前所存在的主要问题,并建议在下一步的研究中重点开展滇红椿种质资源分布及表型性状变异研究,进一步摸清滇红椿的水平分布和垂直分布范围,掌握其表型性状变异规律,为后续开展选择育种和制定种质资源保存策略提供科学依据。

     

    Abstract: Toona ciliate var.yunnanensis is a variation of Toona ciliate,which belongs to Meliaceae,Toona Roem.So far,there are no documents or reports about the research of its intraspecific genetic variation or diversity of Toona ciliate var.yunnanensis.Based on the predecessors,research,this article summarizes the research of phenotypic traits genetic diversity and the main problems in its genetic diversity research.In addition,it is suggested that some further research work should be done on the germplasm resources distribution and,phenotypic traits variation of Toona ciliate var.yunnanensis,aiming to ascertain the horizontal distribution and vertical distribution range and to master the rule of phenotypic distribution range and the rule of phenotypic traits variation,thus providing a scientific basis for subsequent selective breeding and germplasm resources preservation strategy.
