Synthetic Variety - Agriinfo.in

Synthetic Variety. In practical plant breeding, heterosis can be fully exploited in the form of hybrids in cross pollinated species, and also in some self pollinated crops. In cross- pollinated species, heterosis can also be exploited partially in the form of synthetic and composite varieties. Definition of Synthetic Variety: A Variety 【Get Price】
