Abstract:

The relationship between whole genome duplications(WGD)and new plant phenotypes(morphological organ“gigantism”,flowering stage variation,increased secondary metabolites,optimization of agronomic traits,enhanced stress tolerance,etc.)reviewed and discussed systematically and their contribution to evolution and differentiation,and provide prospects for future polyploidy research,which will be helpful by offering important references for innovative research on polyploid plant evolution and molecular breeding of new polyploid crops.

Key words: polyploidy, phenotypic innovation, adaptive evolution, specific diversity
