摘要
牧草是发展草地畜牧业的重要物质基础,但目前牧草常规育种周期长、效率低,远不能满足社会经济发展对优质、高产、高抗牧草新品种的需要。近年来,随着分子标记技术的发展和应用,牧草分子遗传连锁图谱已有大量报道,广泛应用于重要农艺性状的QTL分析、基因定位和比较基因组研究等领域,并将加快牧草分子育种进程。本文详细综述了目前国内外牧草分子连锁图谱研究及应用现状,并分析了存在问题,提出相关建议。
Forage crops are the important basis for development of livestock industry.However,the conventional breeding cycle for forage crops is long and less efficient,which cannot meet the social and economic needs for developing new cultivars with high quality,yield,and strong stress resistance.The development and application of molecular marker technology have accelerated the construction of genetic linkage map and facilitated its application in QTL analysis,gene mapping and comparative genomic research,which accelerated the process of molecular breeding in forage crops.This paper summarized the current research advances in molecular genetic linkage map and its application in forage crops and discussed the existing problems and related suggestions.
