摘要：

An aeroponics system was used for evaluating resistance of peas to Aphanomyces euteiches. Five pea genotypes were tested for resistance to two isolates of A. euteiches at concentrations of 0 to 10,000 zoospores per milliter. Pea genotypes reacted differently to isolates of A. euteiches. Genotype 86-2231 demonstrated the lowest amount of disease and Dark Skin Perfection the highest. Isolate 467 produced consistently higher disease scores than isolate FBI. Inoculum concentration and isolate X concentration effects were significant. This study provides evidence that an aeroponics system can be useful in evaluating the reaction of peas to A. euteiches.
