Abstract

The scope of selection depends on the magnitude of variability in the material under selection and the extent to which the desirable characters are heritable. An appraisal of the variation and heritability of both qualitative and quantitative characters is therefore desirable to assess critically the value of the material under study for its further utilization either in selection or hybridization programme. Castor with its great multiplicity of forms and types, as it is grown under diverse agro-climatic conditions is subjected to such a study and the variations on the qualitative characters are presented. The standards are also fixed for describing these characters.
