Common bean (Phaseolus vulgaris) consists oftwo major geographic gene pools, one distributed in Mexico, Central America, and Colombia and the other in the southern Andes (southern Peru, Bolivia, and Argentina). Amplification and sequencing of members of the multigene family coding for phaseolin, ...

Progress on the observations regarding genetic variability in some Phaseolus spp. is summarized, based on an analysis of phaseollin and isozime variability. In a group of 270 cv. from Latin America, most of them wild, the variability of 8 loci of isozimes was analyzed. Binding data of 5 of these ...

Pythium root rot constitutes a highly damaging constraint on the common bean, Phaseolus vulgaris L., grown in several areas of Eastern and Central Africa. Here, this food legume is cultivated intensively under poor conditions of crop rotation due to the exiguity of the land in the region. Yield l...

Uni-2, a dominant mutation that affects leaf development in Phaseolus vulgaris, is described. The mutant type is characterized by the production of unifoliolate true leaves as opposed to the trifoliolate true leaves that characterize the wild-type phenotype of this species. Segregation data from ...

The lima bean, Phaseolus lunatus L., is a bean species with a broad distribution in the Americas that rivals that of common bean (P. vulgaris). In order to better understand the organization of genetic diversity and the pattern of domestication in lima bean, a review was conducted of the availabl...

Three RFLP maps, as well as several RAPD maps have been developed in common bean (Phaseolus vulgaris L.). In order to align these maps, a core linkage map was established in the recombinant inbred population BAT93×Jalo EEP558 (BJ). This map has a total length of 1226?cM and comprises 563 markers,...
