[Method] Interior and exterior qualities of tobacco were compared and identified based on agronomic and economic characters of tobacco in fields. [Result] Yunshai No.1 was better in both agronomic and economic characters. Specifically, the fragrance was dominated by empyreumatique and aroma; the highly-qualified variety is fragrant and sweet, with little irritation, which gives the tobacco smoke a light, mild flavor. As for Virgini- a934, economic characters were better, but agronomic characters were just ordinary. Similar to Yunshai No.l, dominated by empyreumatique and aroma, the variety was with distinctive resin and herbaceous fragrance. What＇s more, it tasted good with high quality and usability. Cunsanpi was ordinary in agronomic characters, and poor in economic characters, with coordinated quality and chemical composition. It is fra- grant and the smoke is clean. However, the quality was not so high and it tasted not so good. Tengruan No.2 was good in agronomic characters, but poor in eco- nomic characters, which gives delicate fragrance, but not clean enough. Waiweiba and Mijie Qinggeng neither taste well nor smell sweet, performing ordinary in agro- nomic and economic characters. Hence, the two varieties seem bad in quality and ranks poorly. [Conclusion] In terms of sensory quality, the varieties from high to low were Yunshai No.1, Virginia 934, Cunsanpi, Tengruan No.2, Waiweiba and Mijie Qinggeng.展开更多

[Method] The research took tobacco varieties including Tiechi in Yiqian, Mushao in Yangxi Tiechi in Chishui, and Liuye in Toupo as test materials to explore development process, quality characteristics and economic traits of different varieties. [Result] The variety of Tiechi in Yiqian had medium growht, moderate growth periods, and the best economic benefits. Total content of aroma matter was the highest in the varieties of Tiechi in Yiqian. Also it had more content of products of browning reaction and products degraded by cembranoids. Besides, volume and quality of aroma were higher, as well as the score of sensory quality. [Conclusion]Comprehensive comparisons suggested that the variety of Tiechi in Yiqian was superior to others at tobacco-growing, economic benefits and quality.展开更多
