Conventional breeding approaches have played a significant role in meeting the food demand remarkably well until now. However, the increasing population, yield plateaus in certain crops, and limited recombination necessitate using genomic resources for genomics-assisted crop improvement programs. As a result of advancements in the next-generation sequence technology, GABs have developed dramatically to characterize allelic variants and facilitate their rapid and efficient incorporation in crop improvement programs. Genomics-assisted breeding (GAB) has played an important role in harnessing the potential of modern genomic tools, exploiting allelic variation from genetic resources and developing cultivars over the past decade. The availability of pangenomes for major crops has been a significant development, albeit with varying degrees of completeness. Even though adopting these technologies is essentially determined on economic grounds and cost-effective assays, which create a wealth of information that can be successfully used to exploit the latent potential of crops. GAB has been instrumental in harnessing the potential of modern genomic resources and exploiting allelic variation for genetic enhancement and cultivar development. GAB strategies will be indispensable for designing future crops and are expected to play a crucial role in breeding climate-smart crop cultivars with higher nutritional value.
直到现在,传统育种方法在很好地满足粮食需求方面发挥了重要作用。然而,人口不断增长、某些作物产量停滞不前以及有限的重组,使得有必要利用基因组资源开展基因组辅助作物改良计划。由于下一代测序技术的进步,基因组辅助育种(GAB)得到了显著发展,以鉴定等位基因变异并促进其在作物改良计划中的快速有效整合。在过去十年中,基因组辅助育种在利用现代基因组工具的潜力、挖掘遗传资源中的等位基因变异以及培育新品种方面发挥了重要作用。主要作物泛基因组的可用性是一项重大进展,尽管其完整程度各不相同。尽管采用这些技术本质上是基于经济因素和成本效益分析来决定的,但这些技术能产生大量信息,可成功用于挖掘作物的潜在潜力。基因组辅助育种有助于挖掘现代基因组资源的潜力,并利用等位基因变异进行遗传改良和品种培育。基因组辅助育种策略对于设计未来作物将不可或缺,预计在培育具有更高营养价值的气候智能型作物品种方面发挥关键作用。
