菊花分子育种研究进展

Advances in Chrysanthemum Molecular Breeding

对菊花分子育种的研究起源于20世纪90年代初,导入外源基因的主要目的是改变菊花的株型、花色,提高抗虫性、抗病性,增强对寒冷、干旱、盐碱的耐性。近年来,选用不同类型的启动子构建新型载体的研究也为改善菊花育种工作提供了参考。这些都预示着菊花分子育种的研究逐渐走向全面和成熟。

Study of chrysanthemum molecular breeding originated in the early 1990s. The main purpose of transfering foreign genes into chrysanthemum is to change the plants height, flower color, increase insect and disease resistance, improve tolerance to cold, drought, salt stress. Recently, different types of promoters were used in the chrysanthemum study also provide a reference for improving chrysanthemum breeding. All indicate that the study of chrysanthemums molecular breeding gradually towards comprehensive and mature.
