马里兰烟Md609品种株系适应性研究

Study on the Adaptability of Md609 Variety of the Maryland Tobacco

[目的]为探明马里兰烟609品种株系的适应性,丰富马里兰烟种质资源,提高烟叶质量,完善优质马里兰烟生产技术体系。[方法]于2009年在大田条件下,研究了Md609品种不同株系的抗病性、植物学性状、经济性状、化学成分和评吸质量。[结果]Md609株系T3抗病性较好、感病率较低,且其产量、产值、均价表现均相对较好,化学成分较为协调,评吸得分较高。[结论]Md609株系T3更有利于增产增收及内在品质的提高,是马里兰烟种植的适宜株系。

[ Objective ] In order to research the adaptability of Md609 variety of the Maryland tobacco, enrich the germplasm resources of the Maryland tobacco and improve the quality of the tobacco leaves. [ Method ] Disease resistance,botanical character,economic character, chemical components and sensory quality of different strains of Md609 variety of the Maryland tobacco were studied in field conditions in 2009. [ Result] The results showed that the disease resistance of the T3 strain was better than the other strains, and its yield,production value, average price were relatively well,sensory quality and the chemical components of the T3 strain were more harmonious than the other strains. [ Conclusion] T3 strain is conducive to enhance the inner quality and increase the economic benefit,it is the appropriate strain for the Maryland tobacco.
