Overview

To build on the understanding of the genetic and sociocultural factors underlying the diversity present in Malawian beans by quantifying and describing the variability found within major preferred seed classes. Germplasm acr-,msions will be collected and sorted on the basis of seed type and screenedagronomic characteristics. Research will

include socio-cultural investigations of small-scale farmers’ cultivation practices and preferences.

A second major focus will be on screening for differential disease reaction within the major seed classes; identification of disease resistant genotypes in several preferred seed types that are also acceptable on agronomic and culinary grounds; collection of information on small farmer bean cultivation, use practices and methods of disease control.
