摘　　要：通过人工接种的方法对5类野生马铃薯材料进行了马铃薯Y病毒(PVY)的抗性鉴定和筛选。它们对PVY抗性存在明显的差异,其中Solanum stoloniferum(S.A2)×S.stenotomum(104)和S.stoloniferum(S.A5)×S.stenotomum(105)组合抗性最强,属于抗病群体,S.chacoense×S.stenotomum(103)组合属于中抗群体,S.chacoense(102)和S.demissum(101)组合属于感病群体。并从中筛选出一批抗PVY的育种材料:0级抗性材料108份,1级抗病材料56份,3级抗病材料94份。Through artificial inoculation, 5 wild potato populations were evaluated and screened for resistance to potato virus Y （PVY）. There was apparent difference in resistance to PVY in the five wild potato populations. Solanum stoloniferum （S.A2） × S. stenotomum（the population 104）and S. stoloniferum （S.A5） × S. stenotomum （the population 105） were resistant to PVY, S. chacoense x S. stenotomum（the 103 population） was moderately resistant to PVY, and S. chacoense×（the 102 population） and S. demissum×（ 101 ） were susceptible to PVY. Some resistant genotypes were selected out from these five populaitons, i.e. 108 genotypes in grade 0, 56 genotypes in grade 1, and 94 genotypes in grade 3, which may be used as parents in potato resistant breeding to PVY.
