Comprehensive Evaluation Of Bred Flue-cured Tobacco In Bijie Prefecture

In this study, three areas of six arches varieties of materials, attempts toanalyze the differences of yield and quality performance in the species and theecological,Provide for the rational use of tobacco varieties produce high qualityspecialty reference, self-fertile varieties of Bijie and cultivars current systematicevaluation in terms of the level of quality and character styles, initially defined thecharacteristics of flue-cured tobacco varieties Bijie sensory quality characteristics andstyles of aspects, Initially identified the features of Bijie specialty tobacco variety inthe aspect of sensory quality and characteristic style. provide a basis for optimizingthe variety layout and industrial use. According to the experimental results andanalysis, preliminary conclusions are as follows:The agronomic characters and economic characters of Bina1performed better in the area ofQixingguan. The chemical composition of Qixingguan performed like this, the ratio ofreducing sugar to total sugar was0.97, which was almost the same as that of Yunyan87, and was better than that in Weining; the ratio of reducing sugar to nicotine was15.7, which was higher than that in Weining; the ratio of potassium to chlorine was10.0, which was much more suitable than that of Yunyan87, and performed muchbetter than that in Weining. All in all, the overall chemical composition performedcoordinate. In the area of Qixingguan, the appearance quality of the baking tobacco performedbetter. The colour, maturity, leaf structure, identity, chroma, leaf tissue, flexibility and burnishperformed almost the same as that of Yunyan87, and the indentity in Weining was much thinnerthan that in Qixingguan, and it performed better in Weining than that in Qixingguan. The sensoryquality in Qixingguan performed better. In the plots of Qixingguan, the sensory quality of Bina1was a little worse than Yunyan87. The sweet frangrance of Yunyan87performed a little moreprominent than that of Bina1. The smoke of Bina1was drier, and the momentum was slightlylarger. The comprehensive performance in the area of Qixingguan was best.In Weining Jiucaiping2had a good agronomic characters and economic characters and chemical composition had good performance. The ratio of reducingsugar to total sugar was moderate performance in0.88and was a little higher thanHonghuadjinyuan. The ratio of reducing sugar to nicotine was11.8better thanHonghuadajinyuan and the ratio of potassium to chlorine in7.38moderated.Compared with Qixinggaun the overall chemical composition of Jiucaiping2inWeining was more coordination; The identity and gloss of the appearance quality wasbetter than Honghuadajinyuan while the colour, maturity, chroma, leaf tissue, softnesswas equal with Honghuadajinyuan. The total score of Jiucaiping2ranked third inWeining varieties comparison; The sensory quality of Jiucaiping2in Weining hadbetter performance. Its fragrance, sending, concentration and quality of aroma,concentration of aroma, sweet feeling were equal with Honghuadjinyuan. The generalperformance of Jiucaiping2in Weining was best and it was the variety of Hunanzhuongyan preference.The agronomic characters of Nanjiang3performed better in Qixingguan andDafang. The growth vigor was better than that of K326(CK). The whole economiccharacters did well，and the variation coefficient was small, and it has strongadaptability. The chemical composition of Nanjiang3was almost the same as that ofK326. The content of reducing sugar and total sugar were widespreadly on the highside. The ratio of reducing sugar to total sugar, reducing sugar to nicotine andpotassium to chlorine performed better. The overall chemical composition performedcoordinate. The sensory quality of Nanjiang3was a little worse than K326.The delicate and softdegrees were better than that of K326, and the irritation of Nanjiang3was stronger. Thecomprehensive performance of Nanjiang3was better than K326.
