Development of a new flue-cured tobacco variety Zhongyan-100 (CF965) and its application evaluation

Through hybrid recombination, convergent backcross, and pedigree selection, a new flue-cured tobacco variety Zhongyan-100 was developed by crossing the female parent tobacco strain 9201which is resistant to multiple diseases and the male parent variety NC82 which has good quality but is susceptible to brown spot and sensitive to low temperature and short sunshine time. Results showed that the new variety had good adaptability, favored fertile soil, and was easy to cure. It was tolerant to weather spot and resistant to black shank and brown spot. The cured leaf was rich in oil and had shining bright and well-distributed light-orange color. The chemical composition was favorable and well-proportioned to meet the requirements of manufacturing cigarettes with Chinese characteristics. Compared with the main check variety, the new variety's leaf yield was increased by 9.44%, average price increased by 9.24%, ratio of the high and middle class leaf increased by 3.3%, and production value increased by 18.36%. In conclusion, Zhongyan-100 was a variety with favorable characters suitable for China's main tobacco growing areas.
