The question doesn't give much detail to work from, but here are a couple of examples I thought of:
Flavor could be affected by nutrients in the soil or chemicals in the soil or water that the plant absorbs through its roots. These are environmental factors, not genetic.
If the cross is between plants with different genotypes, then the offspring could have traits different from either parent if, for example, each parent had a recessive allele and the offspring inherits both, and thus expresses that recessive allele in its phenotype. This is a genetic factor.
