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 Results from experiments and demonstration for multiple years indicated that the new variety showed a vigorous growth potential and uniformity in the field with well developed upper leaves. 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.

品种是烟叶生产的物质基础，对提高烟叶品质、 增加经济效益和增强抗逆性有重要的作用[1-3]。 烟草 是我国的重要经济作物，烟草行业将育种列为重大 战略性工程，取得了显著的成效，育成审定了云烟 85、云烟 87 等多个烤烟新品种[4-11]，贵州也育成审
定了毕纳一号、南江三号等 9 个烤烟品种[12-15]，并 应用于烟叶生产。但是，由于贵州山区瘠薄的土壤 和“两寒、两旱”等不利生态条件的影响，外引品 种气候斑点病重、早花发生普遍；自育品种虽有较 好的适应性，但卷烟工业对其品质的认可度不高，
