| 摘 要： | 对来源中国，美国等国家的烤烟品种，晒烟品种９种同工酶进行了聚丙烯胺凝胶电泳分析。结果表明：品种间表现多态性的５种同工酶中，烤烟品种成熟期腰叶乳酸脱氢酶，花蕾中的过氧化物酶分别比晒烟品种多一条带，成为烤烟区别晒烟器品种的同工酶标记，这些标记可应用于烤烟和晒烟的杂交后代单株类型鉴定。

| Abstract: | Nine Kinds of isoenzyme were analyzed by the technique of polyacruylamide gel electrophoresis (PAGE) among 23 flue-curdand sun-cured tobacco cultivars from China, America and German. The result showed that the sun-cured tobacco cultivars lackedtwo bands of lactatte dehyrogenase in harvest leaf and peroxidase in flower bud that flue-cured tobacco cultivars possessed- The twobands could be used as the markers of selecting crossing descendants between the two types of tobacco cultivars in breeding. |
