Applications of polyploids in crop improvement

Application of polyploids in crop improvement

1. Utilisation of bridging species
2. Creation of new crop species.
3. Widening of genetic base of existing allopolyploidy

Limitations

1. The effects cannot be predicted.
2. Newly synthesised allopolyploids have many defects like low fertility and genetic instability
3. Small proportion of allopolyploids are promising
