Given the challenges of population growth and climate change, there is an urgent need to expedite the development of high-yielding stress-tolerant crop cultivars. While traditional breeding methods have been instrumental in ensuring global food security, their efficiency, precision, and labour intensiveness have become increasingly inadequate to address present and future challenges. Fortunately, recent advances in high-throughput phenomics and genomics-assisted breeding (GAB) provide a promising platform for enhancing crop cultivars with greater efficiency. However, several obstacles must be overcome to optimize the use of these techniques in crop improvement, such as the complexity of phenotypic analysis of big image data. In addition, the prevalent use of linear models in genome-wide association studies (GWAS) and genomic selection (GS) fails to capture the nonlinear interactions of complex traits, limiting their applicability for GAB and impeding crop improvement. Recent advances in artificial intelligence (AI) techniques have opened doors to nonlinear modelling approaches in crop breeding, enabling the capture of nonlinear and epistatic interactions in GWAS and GS and thus making this variation available for GAB. While statistical and software challenges persist in AI-based models, they are expected to be resolved soon. Furthermore, recent advances in speed breeding have significantly reduced the time (3-5-fold) required for conventional breeding. Thus, integrating speed breeding with AI and GAB could improve crop cultivar development within a considerably shorter timeframe while ensuring greater accuracy and efficiency. In conclusion, this integrated approach could revolutionize crop breeding paradigms and safeguard food production in the face of population growth and climate change.
鉴于人口增长和气候变化的挑战,迫切需要加快培育高产耐逆作物品种。虽然传统的育种方法在确保全球粮食安全方面发挥了重要作用,但它们的效率、精度和劳动密集度已经越来越不足以应对当前和未来的挑战。幸运的是,高通量表型组学和基于基因组的辅助育种(GAB)的最新进展为提高作物品种的效率提供了一个有前途的平台。然而,要优化这些技术在作物改良中的应用,还必须克服几个障碍,例如大图像数据的表型分析的复杂性。此外,线性模型在全基因组关联研究(GWAS)和基因组选择(GS)中的普遍应用未能捕捉到复杂性状的非线性相互作用,限制了它们在 GAB 和作物改良中的应用。人工智能(AI)技术的最新进展为作物育种中的非线性建模方法打开了大门,使 GWAS 和 GS 中的非线性和上位性相互作用得以捕获,从而为 GAB 提供了这种变异性。虽然基于 AI 的模型仍然存在统计和软件方面的挑战,但预计这些挑战很快就会得到解决。此外,快速育种的最新进展显著缩短了传统育种所需的时间(3-5 倍)。因此,将速度育种与 AI 和 GAB 相结合,可以在更短的时间内提高作物品种的开发速度,同时确保更高的准确性和效率。总之,这种综合方法可能会彻底改变作物育种的模式,并在面对人口增长和气候变化时保障粮食生产。
