摘要
通过对保山香料烟品种受粉虱危害和自然发病状况的调查,表明粉虱危害与发病率有正相关,但有1个品种表现为负相关。经进一步对4个常栽品种进行人工接种抗性鉴定,表明品种间抗性差异显著,其中BS13表现为高感,克撒锡和柯玛蒂尼表现为中感,BS1有较高的抗性。本研究为筛选抗病品种防控香料烟曲叶病提供了新的途径。
Based on the investigation of the damage caused by whitefly（ Bemisia tabaci） to oriental tobacco and the leaf curl disease incidence, the results showed that damage have a positive correlation with the incidence of leaf curl disease except for one variety.To identity of the resistant of four varieties, which are constantly planted, to leaf curl disease through mechanical inoculation showed the resistance of varieties to the leaf curl disease is different distinctly. BS13 is the most susceptive to this disease, the next are Komotini and Xanthi, BS1 has a higher resistance to this disease. This study provides a new method of selecting a variety resistant to the leaf curl disease.
