Little research has been published about the occurrence of diseases in faba bean such as chocolate spot, ascochyta blight, or rust in Northern Europe. There is also little data about the impact of sowing rate or variety on disease development. Therefore, the purpose of this study was to assess the impact of variety and seeding rate on disease severity at Biologische Bundesanstalt, Bundessortenamt und CHemische Industrie (BBCH) 75 (which is when 50% of pods have reached full length). Five varieties were tested from multiple Northern European countries: Bauska (Latvia), Jõgeva (Estonia), Gloria (Sweden), Julia (Sweden) and Lielplatones (Latvia). Two sowing rates were used: 30 seeds m^-2 (100%) and 36 seeds m^-2 (120%). The sowing rate did not influence disease severity. The varieties which were most damaged by chocolate spot were Gloria and Jõgeva and the varieties least damaged were Julia and Lielplatones. Variety did not influence the severity of ascochyta blight. The variety most damaged by rust was Gloria and the variety least damaged was Julia. The varieties most susceptible to disease Gloria and Jõgeva while Julia was least susceptible. Thus, Julia can be recommended for faba bean production in Northern Europe.

关于蚕豆在北欧发生的疾病，如巧克力斑点，灰霉病或锈病的研究很少发表。关于播种速度或品种对疾病发展的影响的数据也很少。因此，本研究的目的是评估品种和播种率对德国联邦工业和化学工业联合会（BBCH）75（此时有50％的豆荚已达到全长）的病情和严重程度的影响。对来自多个北欧国家的五个品种进行了测试：包斯卡（拉脱维亚），尤加瓦（爱沙尼亚），格洛里亚（瑞典），朱莉娅（瑞典）和利尔普拉托内斯（拉脱维亚）。使用两种播种率：30种子m ^-2（100％）和36种子m ^-2（120％）。播种率不影响疾病的严重程度。受巧克力斑点损害最大的品种是Gloria和Jõgeva，受损害最小的品种是Julia和Lielplatones。品种没有影响灰霉病的严重程度。锈蚀最严重的品种是格洛里亚（Gloria），损坏最少的品种是朱莉娅（Julia）。该品种最容易感染Gloria和Jõgeva，而Julia则最不容易感染。因此，朱莉娅可以推荐用于北欧的蚕豆生产。
