The names of potyviruses and viral-strains have represented the occurrence of predominant pathotypes on predominant crop genotypes. Thus virus nomenclature, but not viral taxonomy, has been decisively influenced by plant-genotype susceptibility and indirectly by host genetic resistance. REsistance to infection (i.e., host range) continues to serve a practical role in differentiating recognized viruses. Plant genes that confer disease tolerance or viral resistance remain a principal means of viral pathotype differentiation, as well as a principal control measure against major viral pathogens. Degrees of genetic diversity among isolates of recognized viruses should not be underestimated, and any system of viral taxonomy should be prepared for flexibility at the species level.
马铃薯Y病毒属病毒及其株系的名称代表了在主要作物基因型上主要致病型的出现情况。因此，病毒命名，而非病毒分类，已决定性地受到植物基因型易感性的影响，并间接受到宿主遗传抗性的影响。对感染的抗性（即宿主范围）在区分已确认的病毒方面仍发挥着实际作用。赋予抗病性或病毒抗性的植物基因仍然是病毒致病型分化的主要手段，也是对抗主要病毒病原体的主要控制措施。不应低估已确认病毒分离株之间的遗传多样性程度，任何病毒分类系统都应在物种层面具备灵活性。
