摘　　要：云烟203系选用MS317为母本、KX13为父本选育而成的烤烟雄性不育杂交种。该品种田间长势强,生长整齐,株形塔形,打顶后近似筒形,茎叶角度适中,叶形长椭圆形。平均打顶株高113.4 cm,有效叶数21片左右,大田生育期127 d左右。抗TMV、黑胫病,中抗南方根结线虫病、青枯病,感赤星病、PVY、CMV。综合经济性状优于或相当于对照K326。烤后原烟外观质量较好,内在化学成分比例协调,同等种植条件下钾含量较对照K32高。该品种是一个品质、抗性、产量、适应性等方面较能兼顾的优良新品种,特别适宜在TMV高发区种植。Yunyan203 was a male sterile hybrid and developed with MS317 as the maternal parent and KX13 as the paterna1 parent.Plants of Yunyan203 grew rather uniformly in the field with tower shapes and column shapes after being topped.The leaf was in long oval with moderate angle between leaf and stalk.The topped plant height of Yunyan203 was 113.4cm with 21 harvestable leaves.Days needed for staying in the field from being transplanted to being harvested was about 127d.Yunyan203 was resistant to TMV and the black shank,moderately resistant to root-knot nematode and Granuville wilt,and was susceptible to brown spot,CMV and PVY.The economic traits was superior to or equivalent to K326（CK）.Yunyan203 possessed better appearance quality and coordination proportion among chemical compositions.Potassium content was higher than that of K326（CK）under the same cultivation conditions.Yunyan203 was a good flue-cured tobacco variety in regarding the quality,the resistances,the yield and the adaptability,etc.It was suitable to grow in area with high incidence of TMV.
