在20世纪,改良马铃薯种薯的生产方法和病原体检测技术已有了稳步的进展。在20世纪初以前,荷兰和德国的科学家们证明剔除表现为卷叶、斑点、皱缩和其它马铃薯退化综合症状的劣株,改良了种薯原种的产量。在1908年,人们认识到用块茎栽植马铃薯的价值,这一方法逐渐被普遍接受,并且,至今仍广泛应用。 In the 20th century, steady progress has been made in the production of improved potato seed and in the detection of pathogens. By the early twentieth century, scientists in the Netherlands and Germany demonstrated that the elimination of inferior strains that appear as involucre, spots, wrinkles and other potato degenerative syndromes improved the yield of seed potato species. In 1908, it was recognized that the value of tuber cultivation of potato, this method has gradually been generally accepted, and is still widely used.
