Abstract:

This paper discusses the obstacle mechanism of distant hybridization of woody ornamental plants. It summarized the applications of distant hybridization in breeding,reviews the ways to overcome the barrier of distant hybrization and the latest progress in the identification of hybrid offspring. It shows the opinion that the distant hybridization breeding of woody ornamental plants is supposed to focus on the molecular mechanism of reproductive isolation,making full use of modern biotechnology to seek the ways to overcome pre-fertilization and post-fertilization barriers to cultivate new resources. In addition,fully exploring the wild woody ornamental plant resources is still one of the effective ways to breed varieties of woody ornamental plants.

Key words: ornamental plant, woody, distant hybridization, hybridization barrier, ways to overcome, identification
