Summary

The results achieved in the development of hybrid sorghums subsequent to the release of CSH-1 have been presented. The performance of this hybrid is in conformity with the earlier findings and confirmed its suitability to the early and medium duration kharif areas and the summer season. The potentialities of this early hybrid in converting traditionally single cropped sorghum tracts into double cropped areas and the feasibility of growing it as an additional off season crop were discussed.

The performance of experimental hybrid msCK60 X IS 3691 (CSH-2) is critically reviewed and an attempt is made to demarcate the area of adaptation for this hybrid. With a 70 per cent. increase in grain yields and comparable fodder yields with local improved strains, it is expected that this hybrid will be released for general cultivation.

The general superiority of hybrids over local varieties in stepping up the genetic potential of yields was brought out.
