Abstract:

To screen out high-quality varieties of flue-cured tobacco suitable for planting in the western tobacco area of Xuanwei City, a field comparative experiment was conducted to study the differences of agronomic characters, incidence of major diseases, economic benefit, stem percentage, chemical composition and sensory quality of ten flue-cured tobacco varieties in 2019. The results showed that the field growth performance of flue-cured tobacco varieties such as ‘Yunyan 105’ and ‘Zhongchuan 208’ was relatively good, and the incidence of four main diseases were all lower than 2.34% for the two varieties, among which the incidence rate of black shin was lower than 0.93%, lower than that of other varieties. ‘Yunyan 105’, ‘Zhongchuan 208’ and ‘Yunyan 97’ had good economic characters based on unit output value, with the output value of more than 71711.70 yuan per hectare, and the ecological adaptability was relatively good. At the same time, ‘Yunyan 105’ had a relatively low average stem percentage (35.98%) and a relatively high average comprehensive score of chemical composition and sensory quality (0.63 and 0.58, respectively), indicating its good market adaptability. While the overall performance of flue-cured tobacco varieties including ‘Yunyan 121’, ‘Yunyan 123’ and ‘Yunyan 116’ was poor, which were not suitable for planting and promotion in the western tobacco area of Xuanwei City.
