A line X tester analysis of combining ability was carried out using four pistillate lines and eight pollen parents in castor for seed length, seed width, thickness of seed, 1000 seed weight, endosperm percentage and oil content. The variances for gca sca showed pre-dominance of additive gene action for all the characters barring oil content. Female SKP-3 was good general combiner for seed width, seed length and oil content and SKP-4 was good general combiner for seed width, 100 seed weight and thickness of seed. Among males SPS-43-3 was the best general combiner for seed length, thickness of seed and 100 seed weight. A parent showing higher mean performance generally proved to be good general combiner. Seed size can be improved through direct selection
