This study was carried out to compare two artificial screening methods viz. Soil Infestation method (SIM) and root dip inoculation technique (RDIT), under glasshouse conditions for the screening of resistant to Fusarium wilt. Both the artificial screening methods; SIM and RDIT were statistically similar in respect of wilt incidence. However, the reaction exhibited by the castor genotypes was varied with artificial screening methods. Mean wilt incidence obtained through SIM (53.9%) was higher as compared to RDIT (44.8%). All the genotypes exhibited comparatively higher wilt incidence when screened through SIM as compared to RDIT. Genotype DCS 9 exhibited resistant reaction (15.8 %) when screened through RDIT but was moderately resistant (32.5 %) when screened through SIM. It was concluded that SIM could also be used for screening of castor genotypes for the resistance to Fusarium wilt disease. However, lower level of resistance could be evaluated efficiently with saving 8-10 days through RDIT as compared to soil infestation method.
