摘要/Abstract

摘要： 针对湖北烟区生态条件,培育适应性强、品质与主栽品种K326和云烟87相当的烤烟新品种。以优质烤烟品种K326的雄性不育系为母本,抗赤星病、黑胫病、根结线虫病和PVY品种龙江911为父本,配制杂交种鄂烤030,并参加湖北省烟草品种试验和全国烟草品种试验。结果表明,鄂烤030中抗黑胫病和根结线虫病,适应性较强。平均产量、产值、均价和上等烟率分别为2 222.10 kg/hm²、48 782.55元/hm²、21.86 元/kg和40.04%。其中,产量和产值分别比主对照品种K326提高了7.10%和11.94%,比副对照品种云烟87提高了8.29%和8.07%;均价和上等烟率与云烟87相当,但比K326提高了2.92%和5.47%。烤后原烟颜色金黄,身份适中,油润感较强;综合物理特性优于对照品种;主要化学成分含量适宜,整体协调性较好;烟叶感官评吸质量档次中等偏上,整体吸食品质略优于对照品种。鄂烤030是一个在品质、经济效益、抗性、适应性等方面均能兼顾的优良烤烟新品种。

Abstract: In view of the ecological conditions in Hubei tobacco growing areas, new flue-cured tobacco varieties with strong adaptability and similar quality to major cv. K326 and Yunyan 87 were bred. A new flue-cured tobacco hybrid variety Ekao 030 was bred with K326 （quality flue-cured female variety） and Longjiang 911 （with resistance to brown spot, black shank, root knot nematode and PVY） as parents, respectively. It was identified and evaluated in Hubei tobacco variety test and national tobacco variety test. The experimental results showed that Ekao 030 possessed good adaptability, resistance to black shank and root knot nematode. The average yield, output value, average price and superior tobacco rate of this new variety were 2 222.10 kg/hm², 48 782.55 yuan/hm², 21.86 yuan/kg and 40.04% respectively. Among them, the yield and output value of this variety increased by 7.10% and 11.94% respectively compared with the main control variety K326, and 8.29% and 8.07% higher than that of Yunyan 87; the average price and the rate of superior tobacco were similar to those of Yunyan 87, but increased by 2.92% and 5.47% compared with K326. The flue-cured leaves of Ekao 030 were rich in oil and moderate in body, and displayed well-distributed golden color. The comprehensive physical characteristics of this new variety were better than K326 and Yunyan 87. Its contents of main chemical components were harmonious, the quality of tobacco sensory evaluation was moderate, and the overall quality of smoking was better than that of control variety K326 and Yunyan 87. In conclusion, Ekao 030 is a new variety with potentials for high quality, remarkable economic performance, strong resistance to diseases and wide adaptability.
