Multi local trials were carried out during the 2014-2015 cropping season simultaneously in three sites: Kasenga, Katanga and Fungurume located in the provinces of Upper Katanga and Lualaba. Five genotypes of bio-fortified climbing common bean: NUC 479, CWARENTINO, NAMULENGA, M 211, CODMLV059 were...
Investigations were conducted at CIAT to develop methodology required to evaluate resistance to Isariopsis griseola inherent in bean germplasm and breeding progeny. Abundant sporulation by the pathogen has been achieved by growing isolates in the lab. on V-8 medium incubated at 19 degrees Celsius...
The biology of Acrosternum marginatum (Palisot de Beauvois) (Heteroptera: Pentatomidae) on common bean, Phaseolus vulgaris L., was studied at a mean temperature of 24@*C (range 19-32@*C) near Palmira, Colombia. Total mean (@+SEM) developmental time from egg to adult was 42.1 @+ 4.2 d. Head capsul...
The value of intra- and interracial populations in common bean (Phaseolus vulgaris L.) needs to be determined in order to create useful genetic variation for maximizing gains from selection, broadening the genetic base of commercial cultivars, and making efficient use of available resources. Five...
Common beans (Phaseolus vulgaris L) contain a number of antinutritional factors such as condensed tannins. Reducing tannin concentration might contribute to improving the nutritional quality of common bean. But polyphenolics are involved in resistance to diseases and pests, and reducing tannin co...
Significant advances in increasing tolerance to the leafhopper Empoasca kraemeri Ross & Moore in common bean have been obtained using a new breeding scheme where yield under leafhopper attack is the principal selection criterion in the evaluation of progenies. However, to further refine this bree...
Se determinó la secuencia completa del ARN genómico del Virus del mosaico común del fríjol (Bean common mosaic virus) cepa NL4 (BCMV-NL4). El genoma viral consta de 10037 nucleótidos excluyendo la cola de poli (A) y contiene una trama de lectura abierta (ORF) de 9666 nucleótidos que codifica una ...
Certain crosses of common bean (Phaseolus vulgaris) result in temperature-dependent hybrid weakness associated with a severe root phenotype. This is controlled by the interaction of the root- and shoot-expressed semidominant alleles dosage-dependent lethal 1 (DL1) and DL2, which communicate via l...
