烤烟雄性不育杂交种云烟206主要性状研究

目的]了解烤烟雄性不育杂交种云烟206的主要特性。方法]以云烟206及其母本MsK346、父本津引1号、K326(对照)为材料进行品比试验,比较云烟206与亲本、对照主要性状的差异。结果]云烟206株高比亲本和对照高,叶数比母本和对照多1～2片,最大叶比对照大,经济性状优于亲本和对照,黑胫病和TMV发病率与亲本和对照相当。农艺性状杂种优势不明显,产值杂种优势明显,均价和上等烟比例对照优势较明显。主要化学成分含量与对照相当,烟叶感官质量比对照好。结论]云烟206是一个农艺性状、经济性状和品质兼顾的优良雄性不育杂交种。

The Major Characters of Flue-cured Tobacco Male Sterile Hybrid Yunyan206

Objective] To study the characters of flue-cured tobacco male sterile hybrid Yunyan206.Method] With Yunyan206 and its female parent MsK346,male parent Jinyin1,K326 as material,the differences of main traits among them were compared.Result] The plant height of Yunyan206 was higher than that of its parents and CK,the leaf numbers were 1 to 2 pieces more than female parent and CK,the width of the biggest leaf was larger than K326,the major economic traits were better than that of its parents and K326,the field occurrence of Black Shank and Tobacco Mosaic Virus were equal to that of its parents and CK K326.The superiority of agronomic traits of Yunyan206 was not significant,but yield per mu was significant,and the contrast heterosis were more significant on average price and proportion of superior leaf,chemical components contents of Yunyan206 were equal to K326,and sensory taste quality was better than K326.Conclusion] Yunyan206 was an excellent male sterile hybrid with good comprehensive traits in agronomic,economic and quality.
