Pearl millet, a vital staple food and an important cereal, is emerging as crop having various end-uses as feed, food as well as fodder. Advancement in high-throughput sequencing technology has boosted up pearl millet genomic research in past few years. The available draft genome of pearl millet providing an insight into the advancement of several breeding lines. Comparative and functional genomics have untangled several loci and genes regulating adaptive and agronomic traits in pearl millet. Additionally, the knowledge achieved has far away from being applicable in real breeding practices. We believe that the best path ahead is to adopt genome-based approaches for tailored designing of pearl millet as multi-functional crop with outstanding agronomic traits for various end uses. Presently review highlight several novel concepts and techniques in crop breeding, and summarize the recent advances in pearl millet genomic research, peculiarly genome-wide association dissections of several novel alleles and genes for agronomically important traits.
珍珠粟是一种重要的主食和谷物，正逐渐成为一种具有多种最终用途的作物，可作为饲料、粮食和草料。高通量测序技术的进步在过去几年推动了珍珠粟基因组研究。现有的珍珠粟基因组草图为多个育种系的进展提供了见解。比较基因组学和功能基因组学已经解开了几个调控珍珠粟适应性和农艺性状的基因座和基因。此外，所获得的知识距离实际育种实践的应用还很遥远。我们认为，未来最好的途径是采用基于基因组的方法，量身定制设计珍珠粟，使其成为具有优异农艺性状、适用于各种最终用途的多功能作物。目前的综述突出了作物育种中的几个新概念和技术，并总结了珍珠粟基因组研究的最新进展，特别是对几个与重要农艺性状相关的新等位基因和基因进行全基因组关联分析。
