Seed multiplication, agronomic evaluation, and identification of parental genotypes for interspecific hybridization with Phaseolus vulgaris constitute the main research activities carried out in the P. coccineus collection (around 1600 accessions) held by CIAT. In 1985, 3 Ascochyta screening tria...

The genetic variable of seven Phaseolus taxa has been evaluated on the basis of molecular data and the results have used to clarify the phyletic relationships between several taxa of the P. coccineus L. complex. Chloroplast DNA (cpDNA) from 33 populations was digested with six restriction endonuc...

Seed increase of the 1300 accessions from both the cultivated subspecies (coccineus and polyanthus) and the wild forms of Phaseolus coccineus is being carried out at 2 locations of Colombia. In Popayan (1700 m alt., 18 degrees Celsius mean temp., and 2000 mm annual rainfall), 12 plants of each ac...
