Comparison of Greenhouse and Field Screening Techniques for Botrytis Gray Mold Resistance uri icon

abstract

  • Botrytis gray mold (BGM), caused by Botrytis cinereaPers. ex. Fr., is the most destructive foliar disease of chickpeain eastern India, Bangladesh, Nepal, and western Australia.Cool wet weather favors the development of BGM andcan cause upto 100% yield loss. Host plant resistance(HPR) is the most economical and eco-friendly means ofmanagement of BGM. For exploitation of HPR, reliablefield and controlled environment screening techniquesare essential. In general, field screening techniques (FST)are used for large-scale screening of germplasm andbreeding material, and controlled environment screeningtechniques (CESTs) are used to confirm field resistance,screening against different pathotypes/races and to carryout inheritance and race identification studies
