Abstract
PEANUTS are grown under a variety of cropping systems throughout Indonesia and Australia where both protracted and/or intermittent drought stress limit growth and pod yield. The detrimental effects of drought can be modified to some extent through such management options as supplementary irrigation, manipulations in either maturity type or planting date, and intercropping differing maturity cultivars. Increases in pod yield under water-limited conditions are possible also through the identification and selection of cultivars better able to resist and/or adapt to such drought effects. Unfortunately, selection for drought resistance/tolerance has proved difficult in breeding programs because of the need to test large numbers of genotypes in multiple seasons and locations. Large costs in space, time and resources mean that selection for characters other than pod yield at maturity is not feasible. More detailed understanding of the developmental and physiological adaptations enabling superior performance of genotypes under drought stress is therefore needed to identify reliable indices of drought resistance/tolerance. Selection for these traits should complement conventional breeding programs and lead to more efficient use of time and resources.
