Botrytis gray mold (BGM), caused by Botrytis cinerea Pers. ex. Fr., is the most destructive foliar disease of chickpea in eastern India, Bangladesh, Nepal, and western Australia. Cool wet weather favors the development of BGM and can cause upto 100% yield loss. Host plant resistance (HPR) is the most economical and eco-friendly means of management of BGM. For exploitation of HPR, reliable field and controlled environment screening techniques are essential. In general, field screening techniques (FST) are used for large-scale screening of germplasm and breeding material, and controlled environment screening techniques (CESTs) are used to confirm field resistance, screening against different pathotypes/races and to carry out inheritance and race identification studies.
