In 1991, 1992, and 1994, 2,936 accessions of Pisum sativum from the USDA Plant Introduction collection were screened under field conditions for resistance to Mycosphaerella pinodes without replication due to seed supply. These trials were conducted at the Oak Park Research Station at Carlow, Ireland, where conditions are highly favorable for disease expression. In 1995, the 157 most resistant accessions were again screened at Carlow and at the Food and Crops Research Station at Gore, New Zealand, in replicated trials. At both locations, disease was severe and ranged from 20 to 100% foliar blight. Five accessions were as resistant as the commercial cultivar Radley at both locations: PI 142441, PI 142442, PI 381132, PI 404221, and PI 413691. No accessions were more resistant than the cultivar Radley.
1991年、1992年和1994年，由于种子供应问题，对美国农业部植物引种收集库中的2936份豌豆种质在田间条件下进行了抗豌豆球腔菌的筛选，未设重复。这些试验在爱尔兰卡洛的橡树园研究站进行，那里的条件非常有利于病害的发生。1995年，对157份抗性最强的种质在卡洛和新西兰戈尔的粮食与作物研究站再次进行了重复试验。在这两个地点，病害都很严重，叶枯病发病率在20%至100%之间。有5份种质在两个地点的抗性与商业品种拉德利相当：PI 142441、PI 142442、PI 381132、PI 404221和PI 413691。没有种质比品种拉德利更抗病。
