Grain legumes are an important source of nutrition, and contribute a substantial part of dietary protein in many parts of the world. Groundnut (mm eaL. ) is also an important source of edible oil. There are large differences in yield per unit area, wen ten-fold increases, between different locations, and between experimental plots and farmer's fields. Reduced yields are due to a range of factors, primarily climatic, edaphic and biotic. Amg the major yield reducers are pests and diseases, drought, and adverse soil conditions. In addition to breeding for yield Br breeders have incorporated resistances to pests and diseases and other yield constraints. However, tk primary gene pool that is easily accessible to the breeder lacks many of the charactere needed. A range of techniques need to be amlied to grain legumes to wercane these constraints. Wryo rescue may be sufficient where the gene can be found in close relatives, but in many cases more sophisticated techniques are needed. The priorities in breeding efforts for different crops will be diaamaad.
