Study on the adaptability of new flue-cured tobacco varieties in Luohe
In response to the issues of low tobacco yield and poor quality in the Luohe tobacco-growing area,field experiments were conducted to screen new tobacco varieties that are high quality,high yield,and strong disease resistance,providing a reference for enriching the tobacco variety system in Luohe.This paper used the main variety Zhongyan 100 as a control and compared various aspects such as botanical traits,agronomic traits,conventional chemical components,post-roasting tobacco appearance quality,sensory analysis,economic traits,and incidence rate of diseases among different varieties to select the best one.Variety Y20116-91 stood out for its plant height,reaching 191.0 cm,and Y20112-7 had the largest middle leaves area,showing good performance in various indicators.In terms of agronomic traits,varieties Y214044,Y214048,and Y20112-7 had moderate plant height,stem girth,and node spacing,were resistant to lodging,had well-developed root systems,moderately sized leaves,and sufficient space between plant rows,ensuring good ventilation.Varieties Y214022,Y20117-45,and Y20116-91 exhibited good appearance quality and high average price,meeting the production needs of tobacco farmers.From the sensory evaluation data of the middle leaves post-roasting,varieties Y214048,Y20112-7,and Y20112-2 were prone to extinguishing but had a good aroma quality.Comprehensively,varieties Y214044,Y214048,Y214022,Y20112-7,and Y20117-45 showed good performance in appearance quality,chemical components,and field botanical traits and can be further selected.
