Abstract

Forty two experimental hybrids generated through full diallel mating were evaluated in Randomized Block Design during kharif 2019 to study the magnitude of heterosis in sweet corn. Mid-parent heterosis ranged from -21 to 258 for DEW; -25 to 2 for GFW; 3 to 229 for GEY and standard heterosis ranged from 2.13 to 134.95 for DEW; 82.93 to 317.07 for GFW; -15.70 to 68.40 for GEY. Green ear yield exhibited positive significant correlation of mid-parent and commercial heterosis with NKPR, DEW and GFW in common, while no significant association between GEY and TSS was observed. The crosses KH1831 × SC Syn, SC Syn × SC Sel 2 and SC Sel 2 × SC Syn manifested highest mid-parent heterosis for de-husked ear weight, green ear yield and green fodder weight thus utilizing these hybrids in breeding programmes will serve for dual purpose of yield with fodder.
