Common bean (Phaseolus vulgaris) germ plasm accession G 2333 (Colorado de Teopisca) from Mexico was resistant to 380 isolates of the anthracnose pathogen (Colletotrichum lindemuthianum) from 11 Latin American countries. Six frequently used sources of resistance were susceptiblc to many isolates. ...

Breeding of Phaseolus vulgaris L. for resistance to common bacterial blight (CBB) can be done with visual evaluations of symptoms to distinguish broad resistance classes, but a more quantitative measure was needed for genetic studies of resistance. A novel method of evaluation was developed by qu...

If we are to breed common bean (Phaseolus vulgaris L.) for durable resistance to diseases, we must understand pathogenic variation and find sources of resistance. Our first objective was to determine the patterns of pathogenic variation found among isolates of Phaeoisariopsis griseola (PG), the f...

A total of 20,144 common bean (Phaseolus vulgaris) accessions were evaluated in the field at CIAT-Popayan, Colombia, with a mixture of local isolates of the anthracnose pathogen, Colletotrichum lindemuthianum. Of these, 4,939 (24.5%) accessions were resistant, and another 4,410(2l .9%) showed an ...

More than 60 accessions of tepary bean (Phaseolus acutifolius) and five cultivars of common bean (P. vulgaris) were evaluated for disease reactions to different races of wilt-causing Fusarium (F. oxysporum f. sp. phaseoli) under glasshouse conditions; 95% of the tepary accessions were resistant. ...
