Comparison of Synthetic and composite varieties

Synthetic	Composite
Parental components are generally inbreds tested for their GCA	It is not so in composite. The lines are not tested for their GCA.
No of parental lines are limited to 4 - 6 inbreds	No such limit.
Synthetic produced with inbreds can be reconstituted	It is not possible.
Yield performance can be predicted	Cannot be predicted.
