Abstract
A laboratory experiment was conducted to study the response of 45 castor genotypes to drought stress. Five water stress levels were used. The experiment was laid out by complete randomized design with two replications. Ten seeds of each accession were sown in sterilized sand medium and the Poly Ethylene Glycol solution was given to medium. On the tenth day, the observations were recorded. Seedling length, root length and germination percentage were observed. The highest tolerance for germination was shown by RG 2474. The values of shoot length were higher in RG 2474. The maximum root length was seen in RG 2326 and RG 3013. Key words: Castor, genotypes, water stress, in vitro conditions.
