Over the past decade, genomics-assisted breeding (GAB) has been instrumental in harnessing the potential of modern genome resources and characterizing and exploiting allelic variation for germplasm enhancement and cultivar development. Sustaining GAB in the future (GAB 2.0) will rely upon a suite of new approaches that fast-track targeted manipulation of allelic variation for creating novel diversity and facilitate their rapid and efficient incorporation in crop improvement programs. Genomic breeding strategies that optimize crop genomes with accumulation of beneficial alleles and purging of deleterious alleles will be indispensable for designing future crops. In coming decades, GAB 2.0 is expected to play a crucial role in breeding more climate-smart crop cultivars with higher nutritional value in a cost-effective and timely manner.
在过去的十年中,基因组辅助育种(GAB)在利用现代基因组资源的潜力以及表征和利用等位基因变异进行种质改良和品种开发方面发挥了重要作用。未来(GAB 2.0)的 GAB 将依赖于一系列新方法,这些方法可以快速靶向等位基因变异的操纵,创造新的多样性,并促进它们在作物改良计划中的快速高效整合。基因组育种策略,通过有益等位基因的积累和有害等位基因的清除来优化作物基因组,对于设计未来的作物是必不可少的。在未来几十年,GAB 2.0 有望在以具有成本效益和及时的方式培育更具气候智能、营养价值更高的作物品种方面发挥关键作用。
