景东烟区烤烟新品种试验研究

为筛选出适宜普洱市景东烟区推广种植的烤烟新品种,采用大田试验,以云烟87为对照,对9个烤烟新品种的生育期、田间长势、抗性、经济性状以及外观质量进行了对比分析。结果表明,YN220、82-3041、云烟116以及云烟207四个品种的大田总生育期较短,可提早收获;YN220、云烟99以及云烟207在植物学特性和农艺性状上的表现优于或接近云烟87;YN220、云烟99、KRK26、云烟116以及云烟207的原烟外观质量表现与主栽品种云烟87一致;经济性状方面,新品种中KRK26在产量和产值上有优势,均价与级指方面则是YN220表现更优异,上等烟比例与上中等烟比例方面云烟99更突出。因此,YN220、KRK26以及云烟99可优先作为拟推广品种,云烟116和云烟207作为备选品种,进一步在景东烟区开展多点、多年试验,深入论证其推广的可行性。

Experimental Study on New Varieties of Flue-cured Tobacco in Jingdong Tobacco Area

In order to screen out new flue-cured tobacco varieties suitable for planting in Jingdong tobacco area of Pu"er city. The field experiment was used to compare the growth period, field growth, resistance, economic characteristics and appearance quality of 9 new flue-cured tobacco varieties with Yunyan 87 as the control. The results showed that the four varieties of YN220, 82-3041, Yunyan 116 and Yunyan 207 had a shorter total growth period in the field and could be harvested earlier. YN220, Yunyan99 and Yunyan207 performed better than or close to Yunyan87 in botanical and agronomic traits. YN220, Yunyan 99, KRK26, Yunyan 116 and Yunyan 207 have the same appearance and quality performance as the main plant variety Yunyan 87. In terms of economic characteristics, among the new varieties, KRK26 has advantages in terms of output and output value. In terms of average price and grade index, YN220 performs better, and Yunyan 99 is more prominent in terms of the proportion of high-quality cigarettes and the proportion of upper-medium cigarettes. Therefore, YN220, KRK26 and Yunyan 99 can be prioritized as the varieties to be promoted, and Yunyan 116 and Yunyan 207 are selected as alternative varieties. Further multi-site and multi-year experiments will be carried out in Jingdong tobacco area to in-depth demonstration of the feasibility of their promotion.
