Online published on 23 December, 2016. Abstract Castor wilt incited by Fusarium oxysporum f. sp. ricini is an economically important disease and reported to cause yield loss of 5 to 95 per cent. In the present investigation fifty two advance breeding lines were evaluated for wilt resistance by Root dip inoculation technique with two replication. Disease incidence varied from 0–100 per cent in different genotypes. The susceptible check JI-35 showed 100 per cent incidence indicating a good spread of the disease, while resistant check 48-1 exhibited 8.33 per cent wilt incidence. Out of fifty two entries tested, two entries viz., SKP-84 and RG2661 recorded less than 10 per cent (0.00–10.00%) wilt incidence which were considered as resistant, seventeen entries recorded10.00 to 25.00% wilt incidence exhibiting moderately resistant reaction, twenty six entries exhibited susceptible reaction(50–75% incidence) and the rest of the five entries viz., K11-1174-1, JC-3, TMV-5, JC-24 and JC-26 were found highly susceptible (75 to 100% wilt incidence).
