烤烟新品种云烟８５是根据基因重组和累加效应原理，用红花大金元与ＳｐｅｉｇｈｔＧ２８杂交选育的云烟２号为母本，Ｋ３２６作父本杂交，经系谱选择，于１９９５年育成。１９９６年１２月通过省级评审，１９９７年１月通过全国烟草品种审定委员会审定。云烟８５原烟多为桔黄色，光泽强，结构疏松，厚度适中；总糖为２６．０９％，烟碱２．６６％，总氮１．８９％，糖碱比９．８１，氮碱比０．７１，主要化学成分适宜，比例协调；卷烟评吸香气质好，较对照Ｋ３２６稍细腻，香气量足，劲头适中，口感舒适柔和，具有典型的清香型风格。其综合性状集红花大金元、ＳｐｅｉｇｈｔＧ２８和Ｋ３２６优点于一体。经３年株系鉴定，２年云南省区试，２年全国区试和３年生产试验示范，云烟８５平均亩产１８２．４３ｋｇ，均价５．２０元／ｋｇ，亩产值为９７９．６３元，上等烟比例４３．０３％。比对照Ｋ３２６亩产增加６．１７％，均价提高０．６元，亩产值提高１５８．３９元，增加１９．２９％，上等烟增加１１．０５个百分点。云烟８５高抗黑胫病，中抗南方根结线虫病，抗ＴＭＶ能力比对照Ｋ３２６强。农艺性状稳定，变异系数小于Ｋ３２６。具有优质、稳产、适应性广、抗逆力强、耐肥和易烘烤等优点
Yunyan 85, a new variety of flue-cured tobacco, was bred in 1995 by using the gene recombination and additive effect principle, using Yunyan No.2 as the female parent and K326 as the male parent through the hybridization of Spear’s Golden Flower and SpeightG28. In December 1996 passed the provincial accreditation, January 1997 passed the National Tobacco Varieties Approval Committee validation. The content of total sugar was 26.09%, nicotine was 2.66%, total nitrogen was 1.89%, the ratio of nicotine to base was 9.81, the ratio of nitrogen to alkali 0.71, the main chemical composition is appropriate, the proportion of coordination; cigarette evaluation of good aroma, compared with the control K326 a little delicate, aroma amount of foot, moderate momentum, soft and comfortable taste, with a typical fragrance style. Its comprehensive character sets safflower Daikin elements, SpeightG28 and K326 advantages in one. After 3 years of strain identification, 2 years of Yunnan Province, 2 years of national district test and 3 years of production demonstration, Yunyan 85 average mu produce 182.43kg, the average price of 5.20 yuan / kg, the output value of 979.63 Yuan, 43.03% of the finest smoke. A rise of 6.17% over the control K326 mu, an average price of 0.6 yuan, an increase of 158.39 yuan per mu, an increase of 19.29%, and a 11.05 percentage point increase of the finest smoke. Yunyan 85 highly resistant to black shank disease, resistance to southern root knot nematode disease, anti-TMV ability than the control K326 strong. Agronomic traits stable, coefficient of variation is less than K326. With high quality, stable production, wide adaptability, strong resilience, resistance to fat and easy baking
