Abstract:

Molecular biology techniques can be used to improve the precision and efficiency of flower directive breeding. In various molecular breeding techniques, the transgenic is the most widely used one, the gene editing and next generation sequencing (NGS) techniques have been more and more adopted in recent years. In this article, we reviewed the recent flower breeding studies in color, fragrance, plant shape and resistance breeding using transgenic and gene editing. In addition, we introduced how NGS was used in molecular mechanism, gene localization and molecular marker development, which could empower in breeding. Finally, we make the suggestions on how to use new molecular biology techniques in directive breeding, aiming at providing references for the directive breeding of ornamental plants with novel flower colors, fragrance, morphology and stress tolerance.

Key words: flower, directive breeding, transgenic techniques, gene editing, next generation sequencing (NGS)
