Abstract:

This paper reviews the polyploid induction pathways such as in vitro doubling induction,2n-gametes induction,sexual hybridization,and separation of endopolyploidy,as well as polyploid identification methods including morphology,cytology,and chromosome counting in Phalaenopsis polyploid breeding,and the recent achievements in Phalaenopsis polyploid breeding were summarized. Furthermore,the perspectives were proposed as follows: testing different chemical reagents and plant materials,strengthening the research and utilization of 2n gametes,strengthening the combination of sexual hybridization,cell fusion,and polyploid induction techniques,and enhancing the research and application of induced plants.

Key words: Phalaenopsis, polyploid, breeding, research progress, prospect
