7个烤烟品种烟叶质量和经济性状及上部烟叶的比较研究

The Leaf Quality and Economic Characters of Seven Flue-cured Tobacco Varieties and the Comparative Study on Their Superior Leaves

选取7个烤烟品种KRK26、PVH19、云烟97、南江三号、云烟100、云烟105与云烟87,在湘西凤凰县开展大田品种比较试验,研究各品种烟叶的外观质量、吸食质量、上部烟叶开片程度及上部烟百分率、经济性状。结果表明:①上等烟百分率以KRK26、云烟97、云烟100较高(均大于40%),外观质量以KRK26、南江三号、云烟105、云烟97及云烟87较好,吸食质量以云烟105、云烟100、南江三号和云烟87较好;②上部烟叶开片程度最好的为云烟100和云烟97,其次为KRK26和云烟87,初烤烟中上部烟所占百分率以云烟105、云烟100最低(均为33.6%);③产值高低依次为KRK26>云烟100>南江三号>云烟105>云烟97>云烟87>PVH19;④综合分析可知,各品种中以云烟100、云烟105与云烟87的综合特性较好。

A field comparative trial among seven flue-cured tobacco varieties（KRK26,PVH19,Yunyan97,Nanjiang No.3,Yunyan100,Yunyan105 and Yunyan87） was conducted at Fenghuang County of Hunan Province in China.The appearance quality,smoking quality,and economic characters of tobacco leaf and the extension level and smoking rate of superior leaf of each variety were comparatively studied.The results showed that the KRK26,Yunyan97 and Yunyan100 have higher percentage of the first class tobacco（all over 40%）;the KRK26,Nanjiang No.3,Yunyan105,Yunyan97 and Yunyan87 have better appearance quality;the Yunyan105,Yunyan100,Nanjiang No.3 and Yunyan87 have better smoking quality;the Yunyan100 and Yunyan97 have the highest extension level of superior leaf,the next level was KRK26 and Yunyan87;the Yunyan105 and Yunyan100 have the lowest smoking rate of superior leaf（33.6%）;the order of output value was KRK26 〉Yunyan100〉 Nanjiang No.3〉 Yunyan105 〉Yunyan97 〉Yunyan87 〉PVH19;the Yunyan100,Yunyan105 and Yunyan87 have better comprehensive character among all of the varieties.
