High temperature tolerance in grain legumes

High temperature stress (or heat stress) during reproductive stages is becoming aserious constraint toproductivity of grain legumes as their cultivation is expanding to warmer environments and temperature variability is increasing due to climate change.Large genetic variations exist ingrainlegumesforheat tolerance whichcan be exploited for development of locally adapted heat tolerant cultivars. Heat tolerant cultivars will be more resilient to the impacts of climate change, allow flexibility in sowing dates and enhance opportunities for expanding area of grain legumes to new nichesand croppingsystems.
