The combined effect of drought and heat on grain legumes causes an estimated 18-28% of total yield losses. Climate change is expected to worsen these stresses. Critical yield impacts are foreseen to faba bean, lentil, common bean and chickpea, moderate impacts to cowpea and minor impacts to soybean, pigeonpea and groundnut.
In response, three Product Lines (listed below) target particular challenges in order to improve the production performance of the seven legumes most affected by abiotic stresses and climate change. Given the complexity of these stresses and their interactions with other biotic and abiotic factors, stress tolerance must be sought in combination with other traits relevant for a given crop.
Product Line 1: Drought and low-phosphorus tolerant common bean, cowpea and soybean
Product Line 2: Heat-tolerant chickpea, common bean, faba bean and lentil
Product Line 3: Short-duration, drought tolerant and aflatoxin-free groundnut
