贵州毕节烟区5个烤烟新品种的综合性状评价

Comprehensive Trait Evaluation of 5 New Flue-cured Tobacco Varieties in Bijie,Guizhou

为评价不同烤烟品种的生态适应性和筛选适宜贵州毕节烟区种植的烤烟品种,以云烟87为对照,对贵烟202、湘烟5号、云烟116、CC297和CC27等5个品种的农艺性状、田间自然发病率、经济性状和感官质量进行分析,结合一年两点区域试验分析和综合指数法对各参试品种进行综合性状评价。结果表明,云烟116在两个试验点表现均优于对照,适应环境能力强,属广适性品种;CC27在黔西试验点表现优于对照,但是在七星关试验点表现较差,贵烟202和湘烟5号在黔西试验点表现良好,在七星关试验点表现与对照相当;CC297的均价、上等烟率、一年两点区域试验分析和综合指数评价均差于对照。云烟116的农艺性状、田间自然发病率、经济性状和感官质量等综合表现优于对照,适宜在毕节烟区种植。

In order to evaluate the ecological adaptability of different flue-cured tobacco varieties and to identify flue-cured tobacco varieties suitable for planting in the Bijie tobacco areas of Guizhou,using Yunyan 87 as a control,agronomic traits,natural disease rates,economic traits and sensory quality of Guiyan 202,Xiangyan 5,Yunyan 116,CC297 and CC27 were compared through filed experiments.The comprehensive traits of the varieties were evaluated in combination with a two-point regional test analysis and comprehensive index method.The results showed that Yunyan 116 performed better than the control at the two test sites,and showed strong adaptability to the environment.It was a broadly adaptable variety.CC27 performed better than the control at the Qianxi test site,but performed poorly at the Qixingguan test site.Guiyan 202 and Xiangyan 5 performed well at the Qianxi test site,and their performance at the Qixingguan test site was similar to the control.Average price,rate of first-class tobacco leaves,two-point regional test analysis in one year and comprehensive index evaluation of CC297 were worse than those of the control.The comprehensive performance of Yunyan 116 in terms of agronomic traits,natural disease rate in the field,economic traits and sensory quality was better than the control,and it was suitable for planting in Bijie tobacco areas.
