ABSTRACT
Castor is an important non-edibleoil seed crop. It is affected by many fungal pathogens, among them gray mold of castor is one of the destructive diseases caused by Botryotinia ricini. The present study was aimed to develop screening technique against graymold of castor under in-vitroconditions. Spore suspension of Botroytinia ricini was sprayed on detached spike of different germplasm source (detached spike technique).Inoculated spikes were maintained at 270Ctemperature and 85 % relative humidity in glass house for 7 days. Out of the twenty, few germplasm sources like RG-1139, CI-1 , CI-2 showed better resistant to the gray mold disease. Out of the twenty, few germplasm lines CI-1, CI-2, RG-1139 were showed least susceptibility to gray mold disease when compared to susceptible check DCH-519(95 %).
Key words: Gray mold, Green house, Detached spike technique
