Global challenges and new demands require adaptation of cropping systems. Plant genetic diversity can contribute to adapt and improve crops and create more sustainable agricultural systems. In order to harness this diversity, a unified framework that combines genomic, ecological, and geographical approaches is needed for targeted conservation efforts and breeding strategies. In this review, we discuss the potential of genetic diversity to improve the nutritious and resilient pseudocereal grain amaranth. We emphasize on the utilization of within crop diversity and crop wild relatives. We discuss the impact of hybridization and introgression in facilitating the exchange of genetic material between wild and cultivated amaranth, highlighting their significance in broadening the crop's genetic base. Additionally, we focus on utilization of climate distribution models in predicting the future geographic ranges and their suitability with implications for conservation and future sustainability. We aim to suggest a roadmap for leveraging genetic diversity of underutilized crops to contribute to resilient and sustainable cropping systems in a changing climate.
全球挑战和新需求要求对种植系统进行调整。植物遗传多样性有助于使作物适应和改良，并创建更具可持续性的农业系统。为了利用这种多样性，需要一个结合基因组学、生态学和地理学方法的统一框架，以开展有针对性的保护工作和育种策略。在本综述中，我们讨论了遗传多样性改善营养丰富且适应力强的假谷物籽粒苋的潜力。我们强调作物内部多样性和作物野生近缘种的利用。我们讨论了杂交和渐渗在促进野生苋和栽培苋之间遗传物质交换方面的影响，突出了它们在拓宽作物遗传基础方面的重要性。此外，我们着重于利用气候分布模型预测未来的地理范围及其适宜性，以及对保护和未来可持续性的影响。我们旨在提出一条路线图，以利用未充分利用作物的遗传多样性，为气候变化背景下适应力强且可持续的种植系统做出贡献。
