Castor (Ricinus communis L) is an important non-edible oilseed crop with diversified industrial usage. India is dominating in the production and productivity of castor. Thirteen inbred lines were studied for seed physical characteristics, oil quality, as well as fatty acid profile. Among the inbred studied, the maximum weight of 100 seed was 34.2 g, in JC-26, and maximum oil content was 51.3% in SKI-333. One hundred seed wt showed a positive correlation with % of kernel (r=0.472*) and seed oil content has positive correlation with kernel oil content (r=0.803**). Important oil characteristics for industrial use like specific gravity (g/cc) varied from 0.954 to 0.958 while the viscosity (cp) ranged from 604 to 626. The free Fatty acid as oleic acid was ranging between 4.33 to 6.02%. Among the fatty acid, the ricinolic acid was ranging from 83.93 to 87.02%, the minimum value was in 48-1 while the maximum value of ricinolic acid was recorded in DCS-9 inbred.
Screening for inbreds for quality parameters are useful in further hybridization and variety development.
Ricinolic acid of inbreds were between 84 to 87%.
