Abstract [Objective]To screen out suitable varieties of flue-cured tobacco (Nicotiana labacum L.) in Luoyang tobacco growing area. [Method]With Qinyan 96 as the control, we analyzed the growth period,agronomic characters,disease-resistance,main economy characters, chemical composition and appearance quality of six tobacco varies(lines). [Result]Three varies of LY1306,L1310 and Qushou 2 had good comprehensive characters, which were suitable to be planted in Luoyang tobacco planting area, especially that LY1306 had excellent resistance, good yield and quality benefits. [Conclusion]LY1306 was suggested to be used as a reserve variety and extended in Luoyang tobacco planting area.

优质烟叶的形成受遗传因素、生态环境、栽培技术的共同决定[1-3],在影响烟叶产质量形成的诸多因素中,品种的贡献率约占25%~35%[4-5]。洛阳作为我国重要的优质烟叶产区之一,因生态条件好、生产水平高,所产烟叶备受卷烟工业企业青睐[6-7]。然而,随着连续多年的种植,当前主栽品种秦烟96存在病害加重,經济效益下降的趋势。鉴于此,笔者开展了6个烤烟新品种(系)在洛阳烟区的适应性研究,以期筛选出适应洛阳烟区种植的优良后备品种,满足卷烟工业企业对优质原料的需求,最终达到烟区的可持续发展的目标。
1 材料与方法
1.1 试验地概况 试验于2018年在洛阳市洛宁县王村科技示范园区进行。该土壤类型为红黏土,有机质含量为12.7 g/kg,速效氮48.9 mg/kg,速效磷17.3 mg/kg,速效磷157.1 mg/kg,pH 7.85。
1.2 材料
供试品种分别为LY1306、L1310、渠首1号、渠首2号、金神农1号、秦烟96(对照),共计6个品种(系),其中,LY1306、L1310为洛阳市公司自育烤烟新品系,渠首1号、渠首2号为南阳选育的新品系,金神农1号为湖北中烟提供的种子。……
