一、前言烟草作为一种嗜好用植物很早就被植物学工作者所重视,它是一个有价值的实验材料。植物科学上的许多探索性的工作,首先是用烟草来突破的。文献上第一个植物的种问远缘杂交的研究,是德国植物学家科尔鲁特(K(?)hlreuter)在两百多年前(1761～1765)首次用烟草属中的黄花烟草(N.rustica)和秘鲁烟草(N.paniculata)杂交成功的,成为植物远缘杂交研究的经典。近年

The first species of plant in the literature to ask distant hybridization was studied by the German botanist Kölüter K (?) Hlreuter for the first time over two hundred years ago (1761-1765) (N. rustica) and Peruvian tobacco (N. paniculata) hybridization success, become a classic plant distant hybridization research. in recent years
