Productivity of grain crops in semi‐arid environments is often affected by drought, which is likely to increase due to predicted climate changes. Wild pea ( Pisum fulvum Sibth. however several Pf accessions exhibited lower drought susceptibility indices (i.e., greater stability across environments) than domesticated genotypes. Of special interest are a number of Pf genotypes in which low susceptibility to water stress was coupled with relatively high productivity. The sampling habitats of those low susceptibility–high productivity accessions are characterized by mild (400–530 mm) annual precipitation. Further sampling and evaluation of Pf from such locations may improve our understanding of pea drought adaptation and yield physiology.
