Especially Oriental hybrids have strong fragrance and are deeply loved by people. Lily cut flowers are currently one of the fastest growing flowers in the world, with broad market prospects.

[0003] Polyploidy is one of the ways of plant evolution. Polyploidy has the characteristics of giganticity, low fertility, stress resistance and overcoming the sterility of distant hybridization, especially triploidy has specific qualities and powerful It is favored by horticultural breeders for its vegetative growth advantages. Studies on polyploidy in lilies have been reported, and it was found that tetraploid plants are taller and have more flowering substances. Lily breeding technology ...
