摘　　要：向日葵葵花籽油含有大量的不饱和脂肪酸,选育高品质向日葵品种成为当前重要的育种目标之一。传统育种的方法因其多种限制因素,严重影响了向日葵育种的进程。随着DNA分子标记技术的兴起,传统育种方法结合分子辅助育种明显地加快了育种进程。本研究对向日葵分子标记的开发进行了概述,总结和分析了SSR、RAPD、SNP等分子标记在向日葵遗传多样性分析、指纹图谱构建、遗传连锁图谱构建等方面的应用研究,此外介绍了向日葵QTL定位、品种鉴定及纯度分析等方面的研究进展,并对分子标记在向日葵育种中的应用前景进行展望,为向日葵分子辅助育种提供一定参考。Sunflower seed oil contains a large amount of unsaturated fatty acids.Breeding high-quality sunflower varieties has become one of the current important breeding goals.Traditional breeding methods have severely affected the process of sunflower breeding due to various limiting factors.With the rise of DNA molecular marker technology,traditional breeding methods combined with molecular assisted breeding have significantly accelerated the breeding process.This study summarizes the development of sunflower molecular markers,summarizes and analyzes the application research of SSR,RAPD,SNP and other molecular markers in sunflower genetic diversity analysis,fingerprint map construction,genetic linkage map construction,etc.In addition,sunflower QTL mapping is introduced,variety identification and purity analysis,and prospects for molecular markers in sunflower breeding,providing a certain reference for sunflower molecular-assisted breeding.
