It is a first generation male sterile hybrid that was bred by crossing the female parent MSGDH88, a self-bred line from anther culture, with the male parent Val16. The new variety was certified by the National Tobacco Variety Approval Committee in April, 2015.

The main economic characters of the new variety planted in the suitable regions were obviously batter than those of the control K326. It showed resistance to black shank and weather fleck. The appearance quality and physical properties of the new variety were superior to the control. There was no significant difference between the chemical composition of Guiyan 202 and the control. The sensory properties of the new variety were slightly better than those of the control. It is a good tobacco variety balancing quality with yield and performed well in general, suitable for planting in most tobacco-growing areas in Guizhou, Sichuan, Chongqing and Shannxi.
