Carioca common bean (Phaseolus vulgaris L.) is the most produced and consumed in Brazil. The production of carioca bean is affected by fungal diseases such as anthracnose, caused by the fungus Colletotrichum lindemuthianum. Most sources resistant to anthracnose, used in crosses by breeding programs are not derived from the commercial group or are poorly productive and less adapted. Thus, the objective of this study was to characterize 40 carioca bean cultivars already recommended in Brazil for their reaction to C. lindemuthianum races 65, 73, 81, and 89. The cultivars and the resistant control, BRS Esplendor, were inoculated in a greenhouse with two different experiments for each race. Seedlings with fully expanded primary leaves were inoculated with a suspension of each pathogen race and assessed after 12 d. Among the 40 cultivars assessed, 12.5, 2.5, 12.5, and 15% resistant to one, two, three, and four races of C. lindemuthianum, respectively. The cultivars IAC Formoso, IAC-Carioca Pyatã, IAC-Apuã, VC 15, BRS Notável, and IPR Campos Gerais were resistant to the four races, constituting parental sources of resistance to the pathogen. In regions that favor the occurrence of anthracnose in common bean, cultivars with certain levels of resistance should be selected. Therefore, the important information obtained will be made available to growers and those offering technical assistance to growers.

用于培育针对林德木炭黑炭疽病抗性的番薯豆的潜在亲本

Carioca 普通豆 ( Phaseolus vulgaris L.) 是巴西生产和消费最多的。carioca bean 的生产受到由真菌Colletotrichum lindemuthianum引起的炭疽病等真菌病害的影响。大多数通过育种计划用于杂交的抗炭疽病的来源不是来自商业集团，或者产量低且适应性较差。因此，本研究的目的是描述巴西已经推荐的 40 种carioca bean 品种对C. lindemuthianum的反应65、73、81 和 89 号种族。将栽培品种和抗性对照 BRS Esplendor 接种在温室中，每个种族进行两次不同的实验。用每种病原体种族的悬浮液接种具有完全展开的初生叶的幼苗，并在 12 天后进行评估。在评估的 40 个品种中，12.5%、2.5%、12.5% 和 15% 对C. lindemuthianum的一个、两个、三个和四个小种具有抗性， 分别。栽培品种IAC Formoso、IAC-Carioca Pyatã、IAC-Apuã、VC 15、BRS Notável和IPR Campos Gerais对这四个小种具有抗性，构成了对病原体的抗性亲本来源。在有利于普通豆炭疽病发生的地区，应选择具有一定抗性水平的品种。因此，所获得的重要信息将提供给种植者和为种植者提供技术援助的人。
