摘　　要：Solanum chacoense是马铃薯种中分布范围最广、变异最大的野生种之一,具有抗青枯病、抗马铃薯Y病毒(Potato virus Y,PVY)、抗晚疫病、抗线虫和优良加工品质等特性。为了更好地利用该野生种,从S.chacoense的分类进展、植物学性状、农艺学性状等方面对其基本性状进行了描述,并对其重要抗性资源和在育种中的利用进行梳理,为基于该野生种的种质资源创新和育种利用提供了参考。Solanum chacoense,one of the most widely distributed and highly variable wild species,possesses numerous desirable characteristics such as resistance to bacterial wilt,potato virus Y(PVY),late blight,nematodes,and good processing quality.To make better use of this wild species,its basic characters were described from the classification,botanical characters and agronomic characters,and its important resistance resources and utilization in breeding were summarized,which would provide a reference for germplasm resources innovation and breeding utilization based on this wild species.
