 ABSTRACT

The gray mold of castor is  one of the most  important destructive diseases of castor is gray mold, caused by the fungus Botryotinia ricini.Castor germ plasm lines were screened againt gray mold diseases for the identification of resistance source in   field and also in glass house by using detached spike technique.Among all the germplasm lines, only RG - 1826 germplasm lines showed disease severity of 25%  in field conditions  where as  in  detached spike technique , germ plasm line RG-1826 showed 20 % disease sevearity. Remaining all germplasm lines showed more than 25 % disease severity. Where as in susceptible check DCH -519 showed more than 90 % disease severity. Fifty germplasm accessions were screened by detached spike/ raceme technique in glasshouse and by field fogging technique. Out of the fifty germplasm lines, only one germplasm line RG-1826 showed least susceptible to the gay mold disease.

Key words: Castor, gray mold disease, detached spike technique, Field fogging technique
