ABSTRACT
This paper presents the behaviour of some potato varieties and lines towards the attack of the Phytophthora infestans (Mont) de Bary fungus under the field conditions of the Potato Research and Development Station, Targu-Secuiesc. During the observed period (2001-2003) the appearance of new forms of attack was registered, for example the attack on the stem, on the leaf petioles, as well as a greater number of infected tubers. The greatest number of blighted stems belonged to the varieties Sante and Ostara, and the smallest one was registered in the case of the variety Lady Roseta, followed by Desiree and Nemere. The results prove that there is a direct relationship between the frequency of the attack on the stems and that of the blighted tubers in the case of every variety, except for the varieties Lady Roseta and Nemere at which the smallest number of infected tubers was registered.
