Interactions between common root rot (Aphanomyces euteiches) and peas (Pisum sativum) in Finland

Abstract

Interactions were characterized for the first time between pea cultivars and the fungus Aphanomyces euteiches at Finnish trial sites on soils with and without common root rot caused by the fungus. Seed yield, protein content, growing time, duration of flowering and stalk length were all significantly influenced by the fungus. An average of 35% yield reduction was obtained in trial fields infected with Aphanomyces euteiches. On average, protein content was decreased by 1.4%, growing time was reduced by 9 days, duration of flowering was prolonged by 2 days and the stem length was reduced by 20%. Differences between cultivars were observed. The pea breeding line Jo 1085 showed the best tolerance.
