Modern agriculture is currently facing challenges from a burgeoning population and changing climate, which requires improved crops with adaptation to climate and elite yield and quality traits. While there is a breeding bottleneck caused by intensive selection, gene banks containing conserved wild relatives and landraces can be used as breeding resources. However, with limited genetic information available on these wild relatives, the application has been hindered. With the development of both genomics and bioinformatics techniques, it is now easier to identify the genetic variation in wild species, which can be utilized for the introgression of elite traits. These wild species can therefore play an important role in food security and breeding sustainability.
现代农业目前正面临着人口增长和气候变化带来的挑战,这需要改良的作物具有适应气候和优良产量和品质的特性。虽然密集选择造成了育种瓶颈,但含有保守野生近缘种和地方品种的基因库可以作为育种资源。然而,由于这些野生近缘种的遗传信息有限,其应用受到了阻碍。随着基因组学和生物信息学技术的发展,现在更容易识别野生种的遗传变异,从而可以将优良特性导入其中。因此,这些野生种在粮食安全和育种可持续性方面发挥着重要作用。
