Summary
The Ecuadorian national collection ofS. phureja ssp.phureja Juz. & Buk. was evaluated in two parts in consecutive years in the field for resistance toPhytophthora infestans (Mont.) de Bary. Levels of resistance higher than that of the moderately-resistant tetraploid control were found. Preliminary studies indicate that this resistance is a result of minor genes. Three components of resistance: lesion diameter, lesion number and latent period were all correlated with field resistance as measured by the area under the disease progress curve.
