Breeding Chickpea for Improved Adaptation to the Semi-Arid Tropical Environments uri icon

abstract

  • Chickpea (Cicer arietinum L.), also known as Garbanzo bean or Bengal gram, is the secondmost cultivated grain legume grown globally after dry bean (FAOSTAT data, 2007). It iscultivated annually on an area of about 10 million hectares over 50 countries. Over 80%of its area is in the semi-arid tropics (SAT) that encompass most of south Asia, parts ofsoutheast Asia, a swathe across sub-Saharan Africa, much of southern and eastern Africa,and parts of Latin America. These regions are characterized by high atmospheric waterdemand, a high mean annual temperature, limited and erratic monsoonal rainfall, andnutrient poor soils. The major constraints to chickpea production in SAT include terminaldrought and heat stresses, fusarium wilt and Helicoverpa pod borer. Soil salinity is also amajor constraint to adaptation of chickpea in some areas, particularly in India, Pakistan,Bangladesh, Iran and Australia. High instances of dry root rot are reported from Sub-Saharan Africa and India
