Common bean (Phaseolus vulgaris L.) germplasm was screened for resistance to charcoal rot (Macrophomina phaseolina) under field conditions at Kiboko and Katumani, eastern Kenya. Of the 313 bean accessions evaluated, 50 lines were resistant and six were tolerant to M. phaseolina, the charcoal rot ...

Screening common bean accessions for resistance to charcoal rot (Macrophomina phaseolina) in Eastern Kenya
While symbiotic nitrogen (N2) fixation by G. max and P. vulgaris reduces their need for combined N, N2 fixation under field conditions is rarely maximized. This paper reviews constraints to N2 fixation in these species, then examines the genetic variability recorded for traits affecting N2 fixati...

A collection trip of native Phaseolus germplasm was carried out over a 15-day period in the provinces of Jujuy, Salta, Tucuman, and Catamarca (Argentina) within the alt. range of 700-2200 m.a.s.l. Seeds of 26 wild populations of Phaseolus vulgaris var. aborigineus and of other species were collec...

Discusses ILCA's forage legume work in the Ethiopian highlands with particular reference to trifolium including germplasm collection. Presents data on DM yield, CP percentage and DM digestibility of four trifolium spp. and vicia villosa grown at Shola (Ethiopia) in 1981.
Results are given from a Phaseolus germplasm field study carried out in Southern Nuevo Leon, Mexico: 143 samples of 8 different species. The presence of each one of the species in this part of the country is discussed. (CIAT)

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 ...
