Developing a hybrid bean collection to advance climate-ready bean breeding


The year bean (Phaseolus dumosus Macfadyen) / putative hybrid (Phaseolus dumosus x coccineus) / the scarlet runner (Phaseolus coccineus Linnaeus)

NIAB             CIAT             BBSRC

We will explore a collection of common bean hybrid populations to learn more about their physical characteristics, genetics, responses to disease and ease of use for breeding programs. All information will be made available here and through CIAT’s genebank.

Materials

We have selected 15 populations from within CIAT’s genebank for further study. View a complete list.

Activities

Characterisation

The materials will be grown at two sites in Colombia and their physical characteristics recorded including flowering, seed and root traits.

Disease screening

Material will be grown under controlled conditions at NIAB, Cambridge, UK and tested for responses to white mold, anthracnose and web blight.

Crosses

Crosses will be attempted against a P. vulgaris line to test viability of offspring and ease of use within breeding programs.

Genotyping

All populations will undergo DArT genotyping to learn more about the background of these materials.

By reducing the barriers to inclusion of wild material into breeding programmes, we hope to help breeders produce better beans in a shorter time, and have a positive impact on global food security.
