赣南烟区浓香型特色烤烟新品种筛选试验

Screening of New Flue-cured Tobacco Varieties with Strong Aroma Characteristics in Southern Jiangxi

【目的】筛选适应性强的优良烤烟品种,为江西烟叶生产提供品种资源。【方法】通过引进NC102、F31-2、NX0914等7个烤烟新品种(系)在赣南烟区开展品种比较试验,综合分析不同烤烟新品种在当地生态条件下的光合特性、抗病性、经济性状和内在质量。【结果】在赣南生态条件下,F31-2、NX0914、208103个烤烟品种团棵时间约为39 d,表现早生快发,气候斑点病、普通花叶病、青枯病田间自然发病率低,经济效益较好,比对照种K326高16.2%~41.9%;总氮(1.57%~1.72%)、氮碱比(0.77~0.90)、两糖差(1.52~2.23)等化学成分指标较适宜,烤烟风格为浓偏中+或浓香型,感官质量与K326相当,工业可用性较好,综合表现较佳。NC102、云烟201各指标综合表现一般,中烟100、13-4综合表现中等,对当地生态条件适应性一般。【结论】F31-2、NX0914、208103个新品种值得进一步开展示范推广研究。

【Objective】The study was conducted to screen out excellent flue-cured tobacco varieties with strong adaptability and provide variety resources for tobacco production in Jiangxi.【Method】A comparative experiment of seven new introduced flue-cured tobacco varieties(lines)including NC102,F31-2,NX0914 and etc.,was conducted in southern Jiangxi tobacco-growing area.The photosynthetic characteristics,disease resistance,economic traits and internal quality of different flue-cured tobacco varieties under local ecological conditions were comprehensively analyzed.【Result】Under the ecological conditions of southern Jiangxi,the resettling period of F31-2,NX0914,and 20810 was about 39 days,showing early and rapid growth,low natural incidence of climatic spot disease,TMV and bacterial wilt disease,good economic benefits.The output of these varieties was 16.2%-41.9%higher than that of the control K326.The chemical composition indicators such as total nitrogen(1.57%-1.72%),nitrogen-nicotine ratio(0.77-0.90)and difference of total sugar and reducing sugar(1.52-2.23)were more suitable.The flue-cured tobacco style was moderate(+)-strong or strong flauor type.And the sensory quality was comparable with K326,with good industrial availability and comprehensive performance.The comprehensive performances of NC102 and Yunyan 201 were general,and those of Zhongyan 100 and 13-4 were moderate,with general adaptability to the local ecological conditions.【Conclusion】F31-2,NX0914 and 20810 were worthy of further demonstration and extension.
