本项研究通过对国内外100份烟草种质资源烟叶含钾量的分析测定，鉴定出烟叶含钾量高于20．0mg／g干叶的钾积累高效烟草种质资源5份，对今后开发钾积累高效烟草新品种的选育、合理选配亲本具有重要的参考意义。
In this study, we analyzed the potassium content of 100 tobacco germplasm resources at home and abroad, and identified 5 high-efficiency potassium germplasms with potassium content more than 20.0mg / g dry leaf, Potassium accumulation of efficient new tobacco breeding, rational selection of the parent has an important reference value.
