摘要: 云烟303是以MSK326为母本、rY3为父本选育的烤烟新品种。该品种植株型塔形,叶片长椭圆形,平均打顶株高153.0 cm,有效采烤叶数23~24片,大田生育期约135 d,抗黑胫病(0号小种),中抗赤星病。云烟303植株生长势强于对照KRK26,黑胫病抗性明显优于KRK26,主要农艺性状和经济性状与对照总体相当。初烤烟感官质量与对照KRK26相当,外观质量评分优于对照,化学成分评分与对照相当,物理特性评分低于对照。烤烟新品种云烟303在保持KRK26其他性状的基础上,显著提高了对黑胫病(0号小种)的抗性,该品种适宜在光热条件较好的区域种植。

Abstract: Yunyan303 was a new flue-cured tobacco variety bred by using MSK326 as the female parent and rY3 as the male parent. The plants were tower-shaped with long elliptical leaves, had an average topped plant height of 153.0 cm, produced 23-24 harvestable leaves, and required a field growth period of 135 days. This variety showed resistance to black shank (race 0) and moderate resistance to brown spot. Compared with the control variety KRK26, Yunyan303 demonstrated stronger plant vigor and significantly higher resistance to black shank, while its main agronomic and economic traits were generally comparable to those of the control. In terms of cured leaf quality, the sensory quality of Yunyan303 was comparable to that of KRK26, its appearance quality score was higher than that of the control, its chemical composition score was similar, and its physical property score was lower than that of the control. Overall, while maintaining the other traits of KRK26, Yunyan303 had significantly improved resistance to black shank (race 0). This variety was suitable for planting in regions with favorable light and heat conditions.
