部分烤烟新品种的角斑病抗性调查

摘要

[目的]评价黑龙江部分烤烟新品种的角斑病抗性。[方法]在黑龙江省角斑病常年发病较重的地块调查各个烤烟品种、品系的发病情况。[结果]发现高抗角斑病品种 LJ982、0110－52、0631－112、0206－21和0206－41，其中 LJ982和0206－21较易烘烤，主要经济性状较好，可在生产上示范应用，其他品种可作为抗病育种材料。[结论]研究结果为促进烟叶的优质高效生产提供了理论依据。%Objective] To research the resistance to angular leaf spots of some flue-cured tobacco new varieties in Heilongjiang Province. [Method] The incidence situation of different flue-cured tobacco varieties and lines was investigated in heavy diseased plot of Heilongjiang Province.[Result] High resistance varieties to angular leaf spots were found out, which were LJ982, 0110-52, 0631-112, 0206-21 and 0206-41.Among them, LJ982 and 0206-21 were easy to be cured and showed good economic characters, which could be used in flue-cured tobacco production.Other varieties could be used as tobacco germplasms of resistance breeding.[Conclusion] This research provides theoreti-cal foundation for the high-quality and high-efficient production of tobacco leaves.
