为更好地了解和利用所保存的烟草种质资源,2007年对86份烤烟种质资源的主要性状进行了研究,试验设两次重复,每小区种植22株,各小区随机调查5株.结果表明,主要性状差异表现在株高、茎围、节距、叶数、叶长、叶宽等性状,其变幅分别为110.4～326.2 cm、6.3～12.9 cm、2.5～8.8 cm、15.2～59.0片,42.3～77.2 cm、16.0～38.0cm,变异系数分别为13.5%,9.4%,21.2%,17.1%,10.3%,13.6%,Shannon指数分别达到2.090,2.133,2.167,1.916,2.172和2.189.说明广东省烤烟种质资源在主要性状方面具有丰富的遗传多样性,大部分资源的主要性状可供育种工作者选择利用.

In order to well understand and utilize the conserved tobacco germplasm resources, the main characters of 86 flue-cured tobacco germplasms were studied in 2007. The results showed that the main characteristic difference occurred in plant height, stem,leaf number, pitch, leaf length and leaf width, ranging in 110.4-326.2 cm, 6.3-12.9 cm, 2.5-8.8 era, 15.2-59.0 leaves, 42.3-77.2 cm,16.0-38.0 cm, respectively, and the coefficients of variation were 13.5 %, 9.4%, 21.2%, 17.1%, 10.3%, 13.6%, respectively. The Shannon index reached 2.090, 2.133, 2.167, 1.916, 2.172 and 2.189, respectively. It is concluded that the resources in the main characters of flue-cured tobacco have high level genetic diversity, and the main characters of most resources are available for breeders.
