    Breeding and Characteristics of a New Flue-cured Tobacco Variety Guiyan19

    • 摘要: 贵烟19是利用云烟97变异株,采用系统育种方法培育成的烤烟新品种。该品种田间生长整齐,株型塔形,平均打顶株高104.82 cm,可采叶21.00片,大田生育期128.30 d;中抗黑胫病、青枯病和南方根结线虫病,中感赤星病和TMV,感CMV和PVY,综合抗病性与对照K326相当;烟叶易烘烤,综合经济性状略优于对照K326,原烟外观质量与对照K326和云烟87相当;物理特性优于主对照K326,与副对照云烟87相当;原烟化学成分含量适宜;香型风格与对照K326、云烟87一致,整体感官质量优于主对照K326和副对照云烟 87;综合质量与主对照K326相当,优于副对照云烟87。贵烟19是一个优质、适产、多抗烤烟新品种,适宜在西南区中、低海拔烟区推广种植。

       

      Abstract: Guiyan19 was a new flue-cured tobacco variety developed by systematic breeding method after a variant was found in Yunyan97. The plant of Guiyan19 grew uniformly and was tube-shaped, with the average topping height of 104.82 cm, and the number of available leaves of 21.00, and its field growth stage was 128.30 days. Guiyan19 was moderately resistant to black shank disease, bacterial wilt disease and southern root knot nematode disease, moderately sensitive to brown spot disease and TMV, sensitive to CMV and PVY, with comprehensive resistance similar to K326. The leaves of Guiyan19 were easy to cure, and its synthetic economic traits were slightly superior to K326. Guiyan19 exhibited similar appearance quality of cured leaves to K326 and Yunyan87, while better physical properties than the main control K326 and comparable to the secondary control Yunyan87, respectively. It had favorable content of chemical components, consistent flavor style with K326 and Yunyan87, yet superior overall sensory quality than the control K326 and Yunyan87. The overall quality was comparable to the main control K326 and better than the secondary control Yunyan87. Guiyan19 proved to boast high quality, proper yield, multi-resistance, and is suitable for planting in tobacco growing areas at middle or low altitude of Southwest China.
