Abstract: Heterosis for yield and yield related characters of baby corn was studied using 27 hybrids generated by crossing between nine-lines with three testers in line × testers mating design. The objective of the experiment was to identify the best heterotic combinations for baby corn yield and related traits. Twenty-seven hybrids along with parents and two checks were evaluated in randomized block design with two replications. Most of the hybrid combinations reported the highest magnitude of the mid parent, better parent and standard heterosis for various baby corn yield and yield related traits. The cross combination BBCP-8-2 × BBCH-51-2 has shown the highest mid parent, a better parent and standard heterosis values over checks for baby corn yield per plant. For days to 50% silking the hybrids BBCP-27-1 × BBCH-51-2, BBCP-27-2 × BBCH-95-2 and BBCP-10-1 × BBCH-95-2 resulted in desirable standard heterosis values. Whereas the single hybrid combination BBCP-27-1 × BBCH-51-2 has reported the highest heterotic effects for the number of ears per plant. The highest magnitude of standard heterosis over both the checks was reported for dehusked baby corn weight exhibited by BBCP-8-2 × BBCH-95-2 and BBCP-37-2 × BBCH-95-2. Likewise, the hybrid BBCP-8-2 × BBCH-95-2 exhibited the highest heterotic effects for ear length and the hybrid BBCP-27-2 × BBCH-95-2 exhibited the highest standard heterosis for ear diameter. The hybrid BBCP-8-2 × BBCH-95-2 exhibited the highest magnitude of standard heterosis for the dehusked weight of baby corn.
