Moench)and their F2 have revealed positive mid-parent and better parentheterosis for majority of the characters. Sugar yield was found to bemost heterotic trait, as all the crosses depicted significant positiveheterosis over their mid parent and better parent values in case ofall the contributing characters indicating dominance gene action.Further high inbreeding depression for sugar yield reflected highheterosis during the two seasons for all the crosses suggesting theoperation of non-additive gene action
