1、烤烟品种正反交对Fl代产质量性状的影响王晓亮刘毅赖伟华申昌优刘小平李祖莹饶文¥杨庆根州市公司摘要：为了明确正反交对烤烟F1代杂种优势的影响，以云烟87和G13-5为材料配制正反交组合，比较亲本与正反交F1代的农艺性状、经济性状和化学成分的差异。结果表明:株高、有效叶数、腰叶长这3个农艺性状受父本影响较大，存在较明显的正反交差界效应，而茎围、节距、腰叶宽这3个农艺性状不存在明显的止反交差异效应；G13-5X云烟87、云烟87XG13-5在产量、产值上均显著高于2个亲本，说明云烟87、G13-5作亲本其正反交的杂种优势均较明显;在经济性状方面云烟87XG13-5表现明显

2、的超亲优势，在烟叶化学成分含量上云烟87XG13-5比G13-5X云烟87更为协调，而云烟87烟叶化学成分比G13-5的更优，说明胞质对于烟叶内在品质的影响更大。综合来看，以G13-5作父本、云烟87作母本的杂交组合优势更明显。关键词：烤烟;正反交;杂交F1代;产质量性状;作者简介：王晓亮（1970-）,男，江西临川市人，讲师，主要从事农学教学与科研工作。收稿日期:2017-08-07基金：江西省烟草公司科技专项（赣[2014]6号）InfluenceofReciprocalCrossesbetweenTwoFlue-CuredTobaccoVarietiesonF
