基因分型技术在农作物中应用的研究进展

Research Progress of Genotyping-By-Sequencing Technology in Crops

Genotyping-By-Sequencing(GBS)是一种低成本、高通量的基因分型方法,其主要原理是依赖限制性内切酶降低基因组的复杂性。GBS技术具有误差小,分辨率高等特点,已被广泛应用于稻类、麦类、杂粮、豆类和薯类等作物遗传育种领域,为作物增产、农艺性状分析、精确品种识别、连锁图谱的构建和预测育种等提供了辅助工具。文章对相关研究工作进行了综述,并对其发展前景做了简单展望,以期为从事相关工作的研究人员提供一定的参考,使其在农业领域乃至其他领域更好地发挥作用。

Genotyping-by-sequencing(GBS)is a low-cost, high-throughput Genotyping method that relies on restriction endonucases to reduce genome complexity.GBS technology has been widely used in crop genetics and breeding fields such as rice, wheat, cereals, beans and tubers with low error and high resolution, providing an auxiliary tool for crop yield increase, agronomic traits analysis, accurate variety identification, linkage map construction and predictive breeding.In this paper, the relevant research work was summarized, and its development prospect was briefly prospected, in order to provide some reference for researchers engaged in related work, so that it can play a better role in the agricultural field and even other fields.
