对我所保存的烤烟４０ 份本地品种资源和３３ 份国外品种资源的８ 项性状分析表明： 烤烟本地品种资源和外引品种资源的叶数、移栽至中心花盛开天数、腰叶长宽、株高、茎围和节距等性状的变异系数（ Ｃ Ｖ） 都较大， 遗传基础较广泛； 两地品种资源从播种或移栽至中心花盛开天数、腰叶长宽、茎围等性状， 本地品种与外引品种有极显著的差异， 而叶数、株高和节距差异不显著。外引品种资源的大田生长发育快， 生育期短， 比本地品种资源更快进入生理成熟期， 但适应性差， 宜良种良法配套， 加强田间水肥管理。
The analysis of eight traits of 40 local varieties and 33 foreign varieties of flue-cured tobacco stored in our country showed that: the number of leaves of local varieties and introduced varieties of flue-cured tobacco, the days of transplanting to the center flowers, the length and width of the leaves, the plant height (C V) of stem, circumference and pitch traits were larger and the genetic basis was broader. The cultivars from the sowing or transplanting to the central flower blooming days, the length and width of the lumbar and the stem circumference, There were extremely significant differences among the introduced varieties, but the leaf number, plant height and pitch were not significantly different. The introduction of varieties of resources outside the field of rapid growth and development, short growth period, faster than the local varieties of resources into the physiological maturity, but poor adaptability, Yiliang species good method of supporting and strengthening field management of water and fertilizer.
