烤烟品种间遗传差异及上部烟叶可用性研究进展

Research Progress of the Genetic Differences of Flue-cured Tobacco Varieties and Usability of Upper Leaves

[目的]综述了烤烟品种间遗传差异及上部烟叶可用性研究进展。[方法]综述了烟叶质量与经济性状的品种间差异,阐述了上部烟叶可用性的相关研究进展,并提出了今后上部烟叶利用的进一步研究途径。[结果]烟草品种是影响烟叶质量的重要因素;不同烟草品种的特性不同,对生态因素的要求也存在较大差异,且不同烤烟品种各经济性状表现出明显品种间遗传差异;上部烟叶可用性研究在烟叶新品种选育、栽培技术、成熟采收等方面已经取得了大量成果。如何依据不同产烟区的地形地貌、气候条件、栽培管理特点、工业企业原料需求特点选择种植适宜烟草品种,并制定出一套切实可行的配套措施,已成为今后上部烟叶利用的进一步研究途径。[结论]该研究为提高烟叶品种的科学布局及上部烟叶可用性提供理论依据。

[ Objective ] The research aimed to summary the research progress of the genetic differences of flue-cured tobacco varieties and usa- bility of upper leaves. [ Method] The difference between varieties of tobacco leaf quality and economic characters were summarized, the research progress of the upper part of tobacco leaf usability was expounded, and the further study way of upper leaves was put forward. [ Result] Tobacco is an important factor affecting the quality of tobacco leaf. The different tobacco varieties has different characteristics, also there is big difference to the requirement of ecological factors, and the economic characters of different flue-cured tobacco varieties between different varieties show obvious genetic differences. The usability research of upper leaf in tobacco varieties breeding, cultivation techniques, mature harvest had made a lot of progress. How to choose suitable tobacco varieties according to different production area topography, climate conditions, cultivation management characteristics, material requirement characteristics of industrial enterprises, and develop a set of practical and feasible measures, which has becmne the further study way of upper leaves. [ Conclusion] The study provides the theoretical basis for improving the scientific lay- out of tobacco varieties and the availability of upper leaves.
