摘要：白肋烟（Nicotiana tabacum L.）是混合型卷烟的重要原料之一，国产白肋烟种植品种单一以及产量下降等问题已经成为制约混合型卷烟质量提高的重要因素。选用8个国内主栽白肋烟品种在湖北省恩施市进行大田试验，比较各品种的农艺性状、干物质积累、光合作用能力、烟叶品质及经济产量等差异，旨在评价筛选出在恩施烟区适宜栽种的白肋烟品种。综合比较后认为，鄂烟209表现优于对照品种鄂烟1号，产量、产值相比对照分别高出5.14%、2.80%，可作为当地备选推广品种；鄂烟211、云白1号、云白2号、川白1号与对照的综合表现相当；达白1号与达白2号综合表现差，不适宜在当地栽种。

Abstract： Burley tobacco（Nicotiana tabacum L.） is an important material of blended type cigarette. At present， single planting variety and production decrease restrict the improve of the quality of the blended cigarettes. 8 domestic cultivation varieties were selected for field experiment in Enshi city of Hubei， with the purpose of assessing and screening burley tobacco varieties suitable for planting in Enshi area. Agronomic traits， dry matter accumulation， photosynthetic rate， leaf quality and economic yield of different varieties were analyzed and compared. The results showed that， the performance of Eyan 209 was better than Eyan No.1（CK）. Tobacco yield and output value of Eyan 209 were increased by 5.14% and 2.80% compared to Eyan No.1， respectively； and Eyan 209 could be used as alternative variety for demonstration and promotion； Eyan 211， Yunbai No.1， Yunbai No.2 and Chuanbai 1 had consistent performances with Eyan No.1； Dabai No.1 and Dabai No.2 had significantly lower performance than Eyan No.1 and was not suitable for planting in Enshi city.

品種是决定作物质量、产量、化学成分及品质风格的内在因素，没有良好的品种很难有作物的高产量和高产值[1]。中国白肋烟（Nicotiana tabacum L.）育种研究工作起步较晚，近年来，湖北、云南、四川等省在白肋烟品种选育研究工作中做出了重要贡献，培育出了一系列适宜在当地种植及推广的白肋烟新品种[2-6]。烟草对生态环境有广泛的适应性，但对生长环境非常敏感，环境因子的变化对烟株表型和产量、质量都有很大的影响，因此各产区的烟草风格特性迥异[7，8]。烟叶的化学品质是其基因型与生长环境综合作用的结果，选择适应当地生态环境的品种，将有利于烟草的优质高产[9]。……
