Club root of crucifers, a devastating disease of oilseed Brassicas and Cole vegetables is very difficult to control through conventional methods in different areas due to ineffective. Cultivation of resistant Brassica germplasms against this disease is very cheapest method to manage this disease. Therefore this screening trial was conducted with different Brassica germplasms under growth chamber to identify the source of resistance against this disease. Generally root hair infection test and pathogenicity test (club formation) were done for this purpose. Least root hair infection was found in black sarson (29.42 %), radish (35.49 %) and toria sarson (38.59 %) compare to other Brassica hosts. No complete resistance to root hair infection was found. In pathogenicity test Cabbage (94.4%), Broccoli (61.6%) and Indian mustard (72.2%) were found highly susceptible in compare to Brassica rapa group. White radish (11%) and Cauliflower (16.6 %) showed lowest disease severity than other Brassica hosta. But it is found that root hair infection is present to all Brassica and some non-Brassica hosts and it is non-specific and primary phase of club formation. Therefore White radish and Cauliflower could be considered as a source of resistance against this disease based on pathogenicity test.
