Abstract: The agronomic traits and economic characteristics of Yunyan 97, Yunyan 99, Yunyan 100, Nanjiang 3, Xiangyan 3, Qinyan 96 and K326 ( CK) were analysed through the screening tests in the ecological conditions of Ankang tobacco-growing areas. The results showed that, Nanjiang 3 and Yunyan 99 performed prominently, had better growth potential in the field, more effective leaves, stronger disease resistance, stratified fall-yellow significant, the original appearance of tobacco leaves well, high yield, average price and output, high first class rate and superior middle rate of tobacco. good chemical compatibility. This study suggested that Nanjiang 3 and Yunyan 99 could moderate scale planted as collocation varieties inAnkang Pingli tobacco-growing areas.
