Pathogenic variation of Olpidium viciae isolates on faba bean varieties and other legumes

Faba bean is an important cool-season food legume currently constrained by an emerging gall disease (Olpidium viciae) in Ethiopia's highlands. Variability tests of O. viciae isolates were conducted to determine its pathogenic variation on six faba bean varieties in the growth chamber and eight...

Description
Summary:Faba bean is an important cool-season food legume currently constrained by an emerging gall disease (Olpidium viciae) in Ethiopia's highlands. Variability tests of O. viciae isolates were conducted to determine its pathogenic variation on six faba bean varieties in the growth chamber and eight other legumes in the screen house. Each faba bean variety and legume was inoculated with zoospores suspension (10 6 spores mL −1 ) of each isolate. The variability tests were conducted twice on six faba bean varieties to identify the pathogenic level of 30 O. viciae isolates and the experiments were factorially arranged in a completely randomized design with three replications. There was significant variation (P
