GGE双标图在中间香型烟叶特色彰显度分析中的应用

The application of GGE biplot analysis in neutral flavor type flue-cured tobacco

为探讨各产区中间香型烟叶的特色彰显程度,及其与感官质量、化学成分或外观特征的关系,首次引入GGE分析模型,直观比较分析了7个试点、11个烤烟新材料的中间香型特色彰显度。结果表明,各试点中与特色彰显度相关性较大的指标有:还原糖/总糖(RS/TS,-0.873**)、总氮/烟碱(N/NIC,-0.822*)、烟碱(NIC,0.704*);根据特色彰显度与感官质量,可以把7个试点分为4个区:区1(e1)、区2(e3、e7、e2、e6)、区3(e4)和区4(e5),其中区1的特色彰显度较高,区3和区4的较低;不同试点的烟叶在评吸指标、化学成分或外观特征方面各具典型性特征。不同试验材料的风格特色差别较大,其中g3在不同试点的特色彰显度最高。这将为中间香型烟叶产区的烟叶品质区划和特色品种筛选提供借鉴。

GGE biplot was used to analyze tobacco leaf characteristics of 11 flue-cured tobacco cultivars or lines from 7 growing areas. Characteristics and their correlation with sensory quality, chemical components and appearance quality were evaluated. Results showed that characteristics were significantly correlated with the ratio of reducing sugar to total sugar （-0.873＂＊）, the ratio of total nitrogen to nicotine （-0.822＂）, and nicotine （0.704＊）. Tobacco leaves showed different characteristics from different planting areas. All these were useful for determining best suitable growing areas as well as variety development.
