Abstract: 通过田间小区试验比较了云烟87、云烟97、云烟99、云烟203、PVH19、K326、KRK26和红花大金元8个烤烟品种的农艺性状、病虫害发生率、产量、产值和化学成分差异.结果表明:云烟203、KRK26有效叶数较高,云烟97和云烟99较低;叶面积系数则以云烟99、云烟203、红花大金元和云烟97相对较高,PVH19和云烟87相对较小.云烟99、云烟97、KRK26和红花大金元气候斑明显低于其余品种,而赤星病则以红花大金元、云烟87和云烟97相对高于其余品种.云烟87、云烟97和云烟99初烤烟叶产量、产值最高,而PVH19品种明显较低.云烟99、云烟97和KRK26初烤烟叶糖含量最高,烟碱含量接近适宜范围;糖/碱比以云烟99和KRK26最好,氮/碱比则以云烟99和云烟97最佳.综合田间农艺性状、气候斑和赤星病病情程度、烟叶产量、产值、化学成分等指标的分析结果,云烟99总体表现最好.
