The predicted response (as per cent mean of checks) due to first cycle of selection for grain yield revealed the superiority of sib-mating over selfing in cross I as well as in cross II. The predicted response to selection for grain yield was manifold higher in sib populations than in the respective F3 populations. The magnitude of predicted correlated responses (ignoring the sign) for all characters except tiller number in cross I and days to heading in cross II were also relatively high in sib populations than in respective F3 populations. The average realized response to selection was higher under sib mating (50.64 % and 17.33 %) than under selfing (41.52 % and 14.59 %) in cross I and cross II. Further, the realized response to selection was positive for grain yield, plant height biological yield, harvest index and days to maturity in cross I and for grain yield and biological yield in cross II.
