Abstract

Water solution of DNA fraction of potatoes inhibited the conidial germination of Phytophthora infestans. Susceptible lesions were observed on the interspecific hybrid 96-56 (R1 gene) inoculated with the conidial suspension of Phytophthora infestans (Race 1) germinated both in the water solution of DNA fraction from interspecific hybrid 96-56 (R1 gene) and in that of 1506-b (9) (R1R4 genes).
