Groundnut breeding: constraints, achievements and future possibilities uri icon

abstract

  • Considerable progress has been made at ICRISAT and elsewhere in identifying germplasm lines with multiple resistance to biotic and abiotic stresses. Several high yielding cultivars possessing resistance to insect pests and diseases have been released for cultivation in many countries. However, their impact has yet to be felt. Approaches to overcome problems encountered in resistance breeding are discussed, with particular reference to foliar fungal diseases, aflatoxins, viruses, bacterial wilt, insects, drought, shade and acid soils. Progress in breeding for confectionery requirements and adaptation is also considered. Further gains in yield may be achieved by techniques yet to be applied to this crop, such as interspecific hybridization and genetic engineering to transfer useful genes from wild Arachis species and other sources into A. hypogaea lines
