摘　　要：云烟201系选用Ms8610-711作母本,KX13作父本选育而成的烤烟雄性不育杂交种.该品种主要植物学性状变异系数小,遗传稳定,田间生长整齐一致.株式塔型,打顶后近似筒型,自然株高168.8cm,打顶株高107.5cm,可采收叶19.7片,叶形长椭圆形,茎叶角度中,主脉粗细中等,烟叶产值与对照K326相近,大田生育期110～115d.烤后原烟颜色深黄、金黄色多,光泽中至强,油分有、偏多,结构疏松,叶片厚度适中,质量较好.该品种抗烟草普通花叶病、黑胫病,中抗南方根结线虫病,耐青枯病、黄瓜花叶病,感赤星病、马铃薯Y病毒,是一个品质、抗性、产量、适应性等方面兼顾的优良新品种,特别适宜在烟草普通花叶病高发地区种植.Yunyan201 is a male sterile hybrid, and is developed with Ms8610-711 as the maternal parent and KX13 as the paternal parent. The genetic traits of Yunyan201 have stabilized with very small variation coefficient related to the major botanic characteristics. Plants of Yunyan201 grow rather uniformly in the field with tower shapes and column shaped after being topped. The natural plant height of Yunyan201 is 168.8 cm and 107.5 cm after being topped with 19.7 harvestable leaves. The leaf is in ellipse shape with moderate angle between leaf and stalk, and with moderate leaf midrib; the yield is similar to the yield of K326, and days needed for staying in the field from being transplanted to being harvested is 110~ 115 d. The flue-cured leaves are deep yellow with most in orange color, the luster of the cured leaves is moderate to strong with richer oil and loose structure, and the leaf is in moderate thickness and is good in quality. Yunyan201 is resistant to the TMV and the black shank, moderately resistant to M.incognita; it is tolerate to both the Granville wilt and the CMV; and is susceptible to brown spot and PVY. Yunyan201 is a good flue-cured tobacco variety in regarding the quality, the resistances, the yield, and the adaptability, etc. It is suitable to grow in area with high incidence of TMV.
