适宜山地栽培的烤烟新品种的初步筛选

Preliminary research report on screening new flue-cured tobacco varieties adapted to the mountainous region

从农艺性状、经济性状及青枯病田间抗性表现等方面入手,对引进的8个烤烟品种在山地环境下的适应性进行了初步筛选研究。结果表明,参试品种中,云烟201和云烟203产量分别达到了2 460.0 kg.hm-2和2 323.5 kg.hm-2,高于对照的2 049.0 kg.hm-2;云烟201级指最高达到了0.457,云烟203级指达到0.433接近对照的0.439。供试品种中,云烟203青枯病的病情指数最低,仅为33.8;云烟201的接近对照K326,为45.6。综合分析表明,云烟203和云烟201在产量、农艺性状、抗病性及品质等综合性状方面优于对照品种K326,适宜在南方山地推广种植。

Eight flue-cured tobacco varieties were introduced into mountainous regions. The comparative trials have been conducted in agronomy character, economic property and Granville wilt resistance in the field to select the adaptable flue-cured tobacco cultivars in mountainous regions. It indicated that Yunyan 201 and Yunyan 203 produced higher yield ranging from 2 460. 0 kg · hm^-2 to 2 323.5 kg · hm^-2, and the control K326 was 2 049.0 kg · hm^-2. Of the eight varieties Yunyan 201 produced the highest grade index for 0. 457, Yunyan 203 for 0.433, which were close to the control K326 for 0.439. Yunyan 203 performed the lowest disease index against Granville wilt for 33.8. Yunyan 201＇ s for 45. 6. The results suggested that Yunyan 201 and Yunyan 203 performed a better synthetic characters than K326 with good quality, stable yield and higher resistance against Granville wilt, and they could be extended planting in the mountainous regions.
