To evolve a high yielding castor variety with resistance to jassids. Crosses were effected between SA. 2 (high yielding & short duration) and S. 248-2 (A Maharastra variety with triple bloom). A derivative x1158-32 was identified and evaluated under rainted condition in different research centres as well as in farmer's holdings. The yield data showed that X1158-32 is superior to SA. 2. this recording mean yields of 921 kg/ha (26% increase over SA. 2) in six research centres and 1108 kg/ha (26% increase over SA, 2) in six farmer's holdings. It also recorded 7-42% increased yield over SA. 2. in adaptive research trials conducted throughout Tamil Nadu, This culture being moderately resistant to jassids has been released as strain (TMV. 5) for wide cultivation.
