Common bean is an economically important crop grown in several areas in the world. Among the constraints for this crop development, bean rugose mosaic virus (BRMV) infections can potentially lead to serious yield reduction. Genetic resistance is the most effective control method, and the search for sources of resistance is an essential step. The objective of this study was to biologically characterize the BRMVGO isolate and search for virus resistance in germplasm accessions of Phaseolus vulgaris L. To biologically characterize the isolate, 15 plants, selected from a list of indicators, were inoculated, among them soybean (Glycine max L) and pea (Pisum sativum L). The host range demonstrated that the virus can infect different plant species, reinforcing the need for resistance sources. In order to screen for resistance, 172 P. vulgaris accessions were inoculated with the isolate and scored for disease symptoms at 5, 21 and 30 days after inoculation. Among the evaluated accessions, four exhibited hypersensitive reactions (HR) while the remaining showed typical susceptible reactions. The virus seemed to be restricted and could not be retrieved from the common bean accessions showing HR and they are likely interesting sources of resistance for use in breeding programs.

豆类皱纹花叶病毒分离株的表征及在菜豆种质库中寻找病毒抗性

普通豆是一种经济上重要的作物，在世界上的几个地区都有种植。在这种作物发展的制约因素中，豆纹花叶病毒 (BRMV) 感染可能会导致严重的减产。遗传抗性是最有效的防治方法，寻找抗性来源是必不可少的一步。本研究的目的是对 BRMVGO 分离株进行生物学表征并在菜豆种质中寻找病毒抗性。 为了对分离株进行生物学表征，从指标列表中选出 15 株植物，其中大豆（甘氨酸最大L) 和豌豆 (Pisum sativum L)。宿主范围表明该病毒可以感染不同的植物物种，从而加强了对抗性来源的需求。为了筛选阻力，172 P。普通种质用分离株接种，并在接种后 5、21 和 30 天对疾病症状进行评分。在评估的种质中，四个表现出超敏反应（HR），而其余的表现出典型的敏感反应。该病毒似乎受到限制，无法从显示 HR 的普通豆种质中检索到，它们可能是育种计划中使用的有趣抗性来源。
