Effects of directional selection on yield and component attributes in promising advanced generation progenies of selected exotic X Indian crosses of sorghum as compared to their parents and the corresponding F1 hybirds were studied. Some of the derived lines combined high yields with simultaneous reduction in plant height and days to maturity as compared with the Indian parents. Some derivatives such as 302 (CSV-2), 370 (CSV-3), 168 (CSV-5), 604 (CSV-6) and R-16 (CSV-7R) have also been released for commercial cultivation. It is indicated that with proper choice of parents and emphasis on between family selection, pedigree selection could yield desired results even when character associations tend to restrict progress from selection.
