Mashamba is working on iron biofortification of common bean varieties in Tanzania.
Common bean (Phaseolus vulgaris L.) is the most grown and consumed grain legume in Tanzania and thus an important source of proteins, folate, fibre and minerals.
Mashamba’s PhD study is aimed at improving seed iron content of the Tanzanian bean through:
- Collecting nearly all of the varieties (cultivars and landraces) grown in Tanzania and screen them for seed iron in a multi-location trial, then analyse seed iron content
- Study genetic variability for seed iron content and identify genetic markers for high seed iron content
- The selected high-iron genotypes will be crossed with the widely consumed bean varieties to increase the amount of seed iron
