摘　　要：为了筛选出工农业性状兼优的烤烟新品种,本研究以烤烟品种云烟87为对照,对4个新引进烟草品种云烟121、云烟116、云烟301、云烟119的农艺性状、超微结构、代谢物质、烤后烟质量评价4个方面进行比较分析,结果表明:云烟121品种大田长势相对较好,叶绿体结构完整,叶绿体被膜上的嗜锇颗粒体积较大,数量较多。通过代谢通路富集分析发现,云烟121含有琥珀酸、苯乙酸等有机酸类物质较多,而降烟碱、新烟草碱等烟碱类物质较少,有利于提高烟叶的香气质量和安全性。此外,云烟121品种相较于其他新引进品种,外观质量较好,化学成分较协调,感官质量打分更高且与云烟87风格较为接近。研究结果为品种的更新换代提供可靠的技术支撑,有利于优质原料生产的持续、稳定发展。In order to select a new tobacco variety with excellent industrial and agricultural characteristics was selected,the tobacco variety Y87 was used as the control to compare and analyze the agronomic traits,ultrastructure,metabolites and post baking tobacco quality evaluation of four newly introduced tobacco varieties Y121,Y116,Y301 and Y119.The results showed that Y121 had relatively good field growth,complete chloroplast structure,and a large volume and quantity of osmium loving particles on the chloroplast membrane.Through metabolic pathway enrichment analysis,it was found that Y121 contained more organic acids such as succinic acid and phenylacetic acid,as well as fewer nicotine such as nicotine reducing and new tobacco alkaloids,which are beneficial for improving the aroma quality and safety of tobacco leaves.In addition,compared to other newly introduced varieties,the Y121 had better appearance quality,more coordinated chemical composition,higher sensory quality score,and is closer to Y87.The results would provide reliable technical support for the upgrading of varieties,which is conducive to the sustained and stable development of high-quality raw material production.
