India is the major producer of chickpea, contributing for approximately 65% of the annual world production and at the same time major importer of chickpea. The production of chickpea is limited by various biotic and abiotic stresses throughout the world. There are about 50 pathogens associated with chickpea (Nene, 1980), which include 35 fungi, 9 viruses and 2 bacteria and 4 nematodes. Among the most important biotic stresses that limit chickpea production worldwide, Ascochyta blight is considered to be the most notorious one that hampered the overall yield of the crop (Nene, 1982; Chongo et al., 2000). Pigeonpea (Cajanus cajan L. Millsp.) is an important grain legume crop of the family Fabaceae. It is the most important kharif pulse crop with much higher productivity. Pigeon pea represents about 5% of world legume production (Hillocks et al., 2000) and more than 70% is being produced in India.
