Abstract
In the general, the productivity of pulses is low and due to large number of abiotic and biotic constraints. Thus, major in improvement of pulses have on breeding. Excellent progress through traditional breeding methods has been made in development of varieties resistant to some diseases, e.g., fusarium wilt in chickpea and plg,eOllpea; sterility mosaic in pigeonpea; mungbean yellow mosaic virus (MYMV) in mungbean and urdbean; powdery mildew in urdbean, mungbean and pea; and rust in pea and lentil Similar level of success could not be achieved i11 breeding for resistance to other stresses due to unavailability of high level of in the cultivated and cross compatible wild species. Mutation breeding has been rewarding in development of disease resistant varieties in chickpea and mungbean. Sources of high level of resistance have been identified in the wild species for several biotic stresses. Resistance to some stresses is available only in the wild species, for example, resistance to cyst nematodes and bruchids in wild Cicer. However, limited progress has been made in introgression of resistance from spe1cies into the cultivated species, mainly of barriers to interspecific hybridization cases. Concerted efforts are required to understand and to find the ways to overcome the barriers to hybridization between the cultivated species and the wild species of tertiary gene pool. New tools of biotechnology such as transgenic and molecular marker assisted technologies are now available that can be used to accelerate the progress of crop improvement.
