Adaptability of Flue-cured Tobacco Varieties(Lines)HN2619 in Southern Hunan Tobacco-growing Area
In order to verify the ecological adaptability of new flue-cured tobacco line HN2619 in southern Hunan,field experiments were car-ried out in Jiangyong County,Jianghua Yao Autonomous County,Ningyuan County and Xintian County of Yongzhou City from 2020 to 2022,with Yunyan 87 as the control.The main growth period,botanical traits,agronomic traits,disease resistance,appearance quality,economic traits and chemical components of flue-cured tobacco leaves of the tested varieties were compared and analyzed.Results showed that HN2619 had the characteristics of moderate growth period in the field,tower-shaped plant,more leaves,long elliptical leaf shape,good resistance to common mo-saic and brown spot disease.The yield and output value of HN2619 were similar to those of the control,and its internal chemical composition was equivalent to that of the control.The overall performance of HN2619 was similar to that of Yunyan 87(CK),which showed good ecological adaptability and could be used as an extension variety(line).The demonstration planting area should be increased,and the industrial verifica-tion analysis should be done well,such as the matching of modulation measures and sensory smoking quality analysis.
