    烤烟新品种豫浓香201的选育及特征特性

    Breeding and Characteristics of a New Flue-cured Tobacco Variety Yunongxiang201

    • 摘要: 为提高烤烟品种中烟100对根部病害的抗性和烟叶品质,以中烟100为供体,经EMS诱变、腺毛密度类型检测、黑胫病病圃鉴定等手段培育出烤烟新品种豫浓香201,于2023年4月通过全国烟草品种审定委员会审定。该品种遗传性状稳定,群体整齐一致,田间生长势较强,易烘烤。抗黑胫病(1号小种)和镰刀菌根腐病,中抗赤星病,中感黑胫病(0号小种)、根结线虫病和PVY,感青枯病、TMV和CMV。综合抗病力与对照品种NC89相当,根茎类病害抗性优于中烟100。产量、产值较高,主要经济性状和感官评吸质量优于对照品种NC89和中烟100。烤后原烟外观质量较好,化学成分协调,感官评吸甜感突出,符合目前卷烟原料的质量需要;烟叶成熟集中,适宜粮烟融合和机械化采收。豫浓香201适合在我国黄淮烟区有灌溉条件的烟区种植。

       

      Abstract: In order to enhance the resistance of flue-cured tobacco variety Zhongyan100 to root diseases and its leaf quality, a new variety Yunongxiang201 was bred from Zhongyan100 as the donor and selected by using EMS mutagenesis, glandular trichome density type detection and black shank disease nursery identification. The new variety was approved by the National Tobacco Variety Approval Committee in April 2023. Yunongxiang201 exhibited stable genetic traits, consistent and strong field growth, and was easy to cure. It had resistance to black shank (Race 1) and Fusarium root rot, moderate resistance to brown spot, moderate susceptibility to black shank disease (Race 0), root knot nematode disease and PVY, yet susceptibility to bacterial wilt, TMV and CMV, respectively. The comprehensive resistance of Yunongxiang201 was comparable to NC89, and its resistance to root disease was superior to Zhongyan100. Compared with NC89 and Zhongyan100, Yunongxiang201 had higher yield and output value, and better main economic traits. The variety meets the current quality requirements for raw material of cigarettes, with high appearance quality, coordinated chemical composition, and outstanding sensory evaluation of sweetness. It features uniformly matured leaves, thus is suitable for grain and tobacco fusion and mechanical harvest. Yunongxiang201 is proposed to be planted in Huanghuai tobacco area with irrigation conditions.
