Chickpea (Cicer arietinum L.) is an important food legume grown widely in India for its diverse use in food habit. Chickpea contributes to almost half of the total pulse production of India. Botrytis Grey Mould (BGM) caused by the fungus Botrytis cinerea is a menace in the northern foothill of regions (Uttarakhand state) and north western plains of India. The foliar disease affects the crop at flowering and pod maturation stage which is aggravated under cold and humid climate causing up to 100% yield loss. Resistance to BGM is rare among the chickpea varieties released and few stable donor lines have been reported, which is a bottleneck in the breeding program. Therefore, study was conducted to evaluate wild and NBPGR chickpea accessions against BGM using cut twig technique under laboratory condition. Out of 107 wild chickpea accessions, 6 accessions, namely, ILWC 182; ILWC 188; ICC 17151; ILWC 31; ICC 17207 and ILWC 185 showed resistance reaction against the pathogen. Out of 230 germplasm accessions from NBPGR, only two genotypes IC305587 and IC2792 showed moderately resistant reaction for Pantnagar isolate of Botrytis cinerea. However, further field and multi-location evaluation of the identified accessions are required prior to their utilization in breeding program.
