Resistant breeding of two species of flowerPaperback, 28 January 2016

The method and process of resistance breeding of two species of flower were introduced in the book. The distant hybridization was used for lodging-resistant breeding of Platycodon Grandiflorus and the lodging-resistant offspring were obtained. The results show that the lodging-resistant offspring could be the phenomena of apomixes which was induced by pollen. The Si-ion implantation mutation breeding was used for cold-resistant breeding of Oenothera speciosa and the cold-resistant offspring were obtained that can overwinter in Beijing. The results show that the cold-resistant character can be steadily inherited.
