| Abstract: | Guiyan2, a newly breed flue-cured tobacco variety, was developed by systematic selection from a mutant of K326, and was approved by National Tobacco Variety Approval Committee in 2017.Its genetic traits were stable and grew vigorously in field.Guiyan2 had good adaptability and was easy for flue-curing.Guiyan2 was moderately resistant to black shank and TMV, and its resistance to brown spot disease was better than that of K326, the control variety.Its main economic traits, visual and sensory quality were also superior to K326.Guiyan2 was proved to be a new improved variety, which boasted both industrial application value and agricultural efficiency. |
