烤烟新品种粤烟97的选育及其特征特性

Breeding and Selection of Flue-cured Tobacco New Variety Yueyan97 and its Characteristics

粤烟97(原MS96-7)是以MS9207品系为母本,烤烟品种粤烟96为父本培育的杂交一代烤烟新品种,2009年3月通过全国烟草品种审定委员会审定。该品种植株生长整齐、长势强、株型筒形,着叶均匀,群体结构合理,遗传性状稳定,叶片厚薄均匀,分层落黄好,易烘烤;抗黑胫病,中抗-抗青枯病,中感CMV、TMV,感赤星病,高感PVY,耐肥水,适应我国南方烟区及黄淮烟区种植。与对照K326相比,其烟叶产量提高15.6%,均价提高10.94%,中上等烟比例增加26.28个百分点,产值提高25.5%;外观质量比对照K326明显提高,化学成分、工业使用价值与K326相当。

Yueyan97 （previously MS96-7）, a new flue-cured tobacco variety of F1 generation was developed from the cross between MS9207（female parent） and Yueyan96 （male parent）, passed the evaluation of National Tobacco Variety Evaluation Committee in March, 2009. Yueyan97 had uniform and strong growth, barrel type, uniform leaves, reasonable group structure, stable genetic character, uniform leaf thickness. The leaves yellowed and ripened well and easily, and were easy to cure. Yueyan97 was resistant to black shank, moderately resistant to wilt, yet moderately susceptible to CMV and TMV, susceptible to brown spot and highly susceptible to PVY. Yueyan97 was tolerant to fertilizer and water, and adapted to southern China and Huanghuai tobacco growing regions. Compared with the control variety K326, the yields, average price, the proportion of middle and upper leaves, and the output value of Yueyan97 increased by 15.6%, 10.94%, 26.28%, and 25.5%, respectively. Its appearance quality was evidently superior to that of K326, yet the chemical components and industrial usability was similar.
