美引烤烟新品种(系)适应性对比试验

Contrast Test of Suitability of New Flue-cured Tobacco Varieties(Nicotiana glauca L.) Introducing from America

为筛选适应施甸县烟区种植的烤烟(Nicotiana glauca L.)新品种,对8个美引烤烟新品种的主要生育期、植物学性状、农艺性状、抗病性、经济性状和外观质量进行了田间试验比较分析。结果表明:NCYATA15表现最好,其在株高、叶片数、节距、产量、产值、中上等烟比例、均价、产指以及抗普通花叶病性、赤星病、气候性斑点病等方面均比对照品种MSK326高,二者在其余方面表现接近。NCYATA13、NCYATA14不适宜施甸县种植,建议将NCYATA15作为重点筛选品种,其余品种继续进行深入研究。

In order to screen new varieties of flue-cured tobacco which adapted to plant in flue-cured tobacco growing areas of Shidian County, the main growth period ,botanical characters ,agronomic traits ,disease resistance ,economic characters and appearance quality of eight varieties introducing from America were studied by analyzed comparatively through the field trials.The experimental results indicated that NCYATA15 was the best in the eight varieties.Than the MSK326, the height,blades number, pitch,output,output value,high-middle-quality leaf ratio, average price,yield index, and disease resistance of TMV,brown spot, climate speck of N CYATA 15 were higher.In the other aspect,NCYATA15 was close to MSK326.The NCYATA13 and NCYATA 14 were planted inappropriately in Shidian County.NCYATA15 can be selected as key species,and the other varieties should be further studied.
