Use of genetic resistance is the most practical and economic way to manage anthracnose of common bean. Colletotrichum lindemuthianum, the causal agent of bean anthracnose, is a highly variabile pathogen, and there are no host resistance genes that are effective against all known races of the path...

The initial response of plants to aluminium (Al) is an inhibition of root elongation. In the present study, short and medium-term effects of Al treatment (20??M) on root growth and Al accumulation of two common bean (Phaseolus vulgaris L.) genotypes, VAX-1 (Al-sensitive) and Quimbaya (Al-resistan...

Increased adoption of climbing beans ( Phaseolus vulgaris check for this species in other resources L.) in Kabale district, south-western Uganda, has been limited by scarcity of staking materials, despite the crop's higher yield potential compared to bush bean types when grown on fertile soils. ...

Mulching was highly effective and superior to chemical treatments for the control of web blight (WB) caused in beans by Rhizoctonia solani, the imperfect state of Thanatephorus cucumeris. Plots were established in fields with a history of repeated incidence of WB. Soilborne sclerotia and colonize...

Pedigree selection for seed yield, using early generation yield tests, was practiced from the F2 to F7 in two populations of common bean (Phaseolus vulgaris L.) in three plant densities: 66, 133, and 266 thousand plants ha-1 at CIAT-Palmira, Colombia. The six highest yielding lines selected from ...

Bean germplasm was evaluated at CIAT for resistance to BCMV strains NL-4, NL-3, and NL-5 in order to use them in the national breeding and selection programs in Africa, Europe, USA, and Chile. Ninety-eight lines were selected for an international Bean Common Mosaic/Black Root resistance nursery. ...
During a 3-wk. trip to western Guatemala to collect bean germplasm, 88 seed samples were collected, representing 10 species in different forms. The germplasm involves 3 cultivated species (coccineus, polyanthus, and vulgaris), the ancestral forms of coccineus, lunatus, and polyanthus, and 3 wild ...

Although common bean (Phaseolus vulgaris) is the most important grain legume in the developing world for human consumption, few genomic resources exist for this species. The objectives of this research were to develop expressed sequence tag (EST) resources for common bean and assess nodule gene e...

Single nucleotide polymorphism (SNP) markers are by far the most common form of DNA polymorphism in a genome. The objectives of this study were to discover SNPs in common bean (Phaseolus vulgaris L.) by comparing sequences from coding and noncoding regions obtained from the GenBank and genomic DN...
