基于抗青枯病的烤烟品种适应性及烟叶质量评价

为了有效解决文山烟区青枯病防治的根本方法及筛选后备品种,研究了8个品种(系)在文山烟区的适应性,并进行了烟叶质量评价。结果表明:供试品种中安烟2号和S6在整个生育期具有较好的稳定抗性,烟株田间长势较好,成熟特性好,农艺性状表现优,其产量、产值、均价和中、上等比例在供试品种中最好,具有较好的经济性状,且水溶性总糖、还原糖、总氮、总植物碱、钾离子含量均在适宜范围内,各项化学成分协调;评吸结果表明,安烟2号和S6质量档次为中等偏上,S6属于中间香型,安烟2号属于中偏清香型;安烟2号和S6烟叶质量与特色品种K326接近,青枯病抗性优于主栽品种云烟87和K326,且综合性状亦优于或接近主栽品种,二者都可作为文山烟区后备烤烟品种。

The Adaptability and Quality Evaluation of Flue-cured Tobacco Varieties Based on Bacterial Wilt Resistance

In order to seek an effective solution as the fundamental control method of Wenshan tobacco bacterial wilt and screening reserve, the adaptability and quality evaluation of eight varieties were studied in Wenshan. The results indicated that Anyan No.2 and S6 in growth period have stable resistance and good economic performance, such as good field growing feature, good mature characteristics, good agronomic traits, high yields, high average prices and ratio of medium-topped tobacco. Their chemical compositions are harmonious because total soluble sugar, reducing sugar, potassium content, total alkaloid, and total nitrogen are in the suitable range. The cigarette smoking results showed that Anyan No.2 and S6′s quality grade is medium, S6 belongs to the middle flavor, Anyan No.2 belongs to fen-flavor. The tobacco leaf quality of Anyan No.2 and S6 are similar to special variety K326. The bacterial wilt resistance is better than main varieties Yunyan 87 and K326, and comprehensive characters are upon or near the main varieties, which may be tobacco varieties in Wenshan tobacco growing areas.
