The collection was evaluated was evaluated at the Oak Park Research Center, Carlow, Ireland, where infection by Mycosphaerella pinodes occurs naturally and where confounding diseases such as root rot, wilt, and virus diseases are not chronic. Each pea line was planted in a 1.4 by 1.2 m plot using an Oyjord seed drill. The space between plots was 0.4 m. The control consisted of the susceptible commercial cultivar Solara planted three times throughout the plot area. The trial was planted on 24 April 1991 and selected plots were harvested on 3 September. In 1992 the trial was sown on 4 May and harvested on 18 SeptemberTo ensure uniform infection, plots were inoculated each year with an isolate of M. pinodes obtained from seed supplied by Dr. Anthony Biddle. Isolation was according to the method of Hewett (Plant Pathol. 15:161-163)
