云南省烤烟优良高世代新品系筛选研究

Study on High Generation New Flue-cured Tobacco Lines in Yunnan Province

[目的]对8个高世代新品系进行筛选试验研究,筛选综合表现较好的烤烟新品系。[方法]在云南省烟草农业科学研究院以K326为对照进行小区比较试验,对参试烤烟新品系的农艺性状、经济学性状等进行比较和分析。[结果]4个高世代新品系(141、144、146和147)综合性状略优于对照K326。[结论]该研究可为今后推荐新品系参加省区试提供理论依据。

[Objective] The aim was to study the composite traits of 8 novel flue-cured tobacco lines,and screen out the good overall performance lines.[Method] Eight new lines were planted in test base of Yunnan Academy of Tobacco Agricultural Science,and the agronomic characteristics,resistance,economic and quality traits of them were compared and analyzed with K326 as control.[Result] The overall performance of 4 lines,140,144,146 and 147 were a little better than CK.[Conclusion] The study provides a theoretical basis for new lines to participate regional tobacco variety test in Yunnan.
