ABSTRACT

The potato cyst nematodes (PCN) Globodera rostochiensis and Globodera pallida are considered as being redoubtable pests of potato crop and are subject to strict quarantine regulations in several countries. In Algeria, the potato crop is the most important food crop widely cultivated in different agricultural areas. In this investigation, the response of three potato varieties; Kondor, Spunta and Desiree to the evolution of populations of Globodera spp. was studied. Final population of cysts, eggs and juveniles / kilogram of soil increased significantly in the variety Desiree compared to the initial population. A significant decrease was noticed in the variety Kondor. However, the variety Spunta did not show significance between the final and initial nematodes population. The effect of these nematodes on the tuber yield of various potato varieties was also studied. Variety Kondor produced the best yield while Desiree gave the least. The variety Kondor presented the best results in terms of resistance and yield. It is important to use this variety to control these pests.
