邵阳烟区烤烟适应性品种筛选

Screening of Adaptable Varieties of Flue-Cured Tobacco in Shaoyang Tobacco Area

以引进的8个新品种及2个当地主栽品种(K326及云烟87)为材料,对其生育期、农艺性状、烟株植物学性状、品种抗病性、烤后烟叶经济性状及烟叶外观质量等方面进行考察及分析。结果表明:供试品种20930前期表现较好,但是在大田后期其生长势较弱,株型不佳,长势不好;CS1545综合长势一般,K326也表现出了不易烘烤、易挂灰的现象,建议再进一步观察;HKDN-2和C81-2-2在邵阳地区综合表现较好,可以加大面积推广种植,在邵阳地区应该选择性的扩大面积进行生产试验和示范,作为此次品种区试试验的重点推荐品种;09-18-3和20930这2个品种也可以作为区试试验品种继续试验,考证其是否具有推广效益。

The study and analysis were carried out on the growth period, agronomic traits, botanical traits of tobacco plants, disease resistance, economic characters of tobacco leaves and the quality of tobacco leaf appearance through 8 new varieties and 2 main cultivated varieties（K326 and Yunyan 87）. The results showed that the tested varieties 20930 had better performance in the early stage, but the growth potential was weak in the late field, the plant type and the growth condition were not good. The growth of CS1545 is a general trend. K326 also showed the phenomenon of not easy to bake and easy to hang ash, further observation was recommended. The comprehensive performance of HKDN-2 and C81-2-2 in Shaoyang area was good. It can enlarge the area and promote planting. In Shaoyang, the area of selective expansion should be tested and demonstrated, as the key recommended variety for this variety test. The 2 varieties of 09-18-3 and 20930 can also be used as regional trial varieties to carry out experiments to verify whether they have promotional benefits.
