Fifty nine land races from 42 countries and 62 elite breeding lines developed at Indian Institute of Pulses Research, Kanpur, were screened against Fusarium wilt (race 2) under sick-field. Among land races the per cent wilted plants at seedling and reproductive stages ranged between 0 to 31.5% and 3.1 to 100%, respectively. Eightland races (ILC8632, ILC8666 ILC10729, ILC0, ILC1313, ILC211, ILC68 andILC0) were found highly resistant.The per centage of early wilting among elite breeding lines consisting of ‘desi’ and ‘kabuli’ types ranged between 0 to 28.5% and late wilting ranged between 0 to 100%. In ‘kabuli’ type chickpea, 10 genotypes (IPCK2012-129, IPCK2012-141, IPCK2012-258, IPCK2012-306,IPCK2012-132, IPCK2012-137, IPCK2012-138, IPCK2012-140, IPCK2012-143, IPCK2012-144)) and in ‘desi’ type, 15 genotypes(IPC2012-03, IPC2012-10, IPC2012-20 and IPC2012-28, IPC2012-02, IPC2012-04, IPC2012-05, IPC2012-13, IPC2012-18, IPC2012-19, IPC2012-21, IPC2012-24, IPC2012-25, IPC2012-26 and IPC2012-29) were found highly resistant/ resistant. Local severity index (LSI) was higher for land races (71.7%) compared to elite breeding lines (27.8%). Among elite breeding lines least LSI was noticed in ‘desi’ type (23.6%) in comparison to ‘kabuli’ type genotypes (32.1%). In the present study, high level of resistance was observed in elite breeding lines compared to land races. The genotypes found resistant to wilt in the present study may be exploited for development of Fusarium wilt resistant varieties.
