Genetic improvement of rabi sorghums has not kept pace with kharif sorghums. The variety—hybrid differences are not conspicuous. Improvements obtained through the development of CSH-8R (hybrid) and CSV-8R (variety) are not reflected on a field scale. Subsequent progress to-date is also marginal. There are indications that hybrids could be more stable than varieties during rabi. Yield superiority needs to be built into them. Present female parents with kharif parentage seems to impart temperature sepsitivity to hybrids. Efforts are outlined to develop superior rabi hybrids that combine yield advantage and stability of performance.
