Alliums are essential crops in daily diet for their flavor and medicinal value, which are highly cross pollinated crops, prone to inbreeding, or continuous selfing, and biennial crop cycles import complexity in the alliums improvement. However, interspecific hybridization aided for the introgression of genes responsible for resistance to pests, diseases and abiotic factors, which can minimize or eliminate the use of plant protection agents. Furthermore, the transfer of novel metabolites and odor molecules into edible Allium species thus could be beneficial to human health. It increases the genetic diversity by gaining new gene reservoirs, and useful in the genetic improvement of alliums. In this scenario, the wild relatives of alliums could be used to introduce resistant genes, as the genus Allium has an untapped gene pool. However, understanding species compatibility is a need for commencing a hybridization program and an important aspect in introgression breeding. We reviewed the attempts at interspecific hybridization among alliums for cross compatibility and desirable trait introgression in this review. As a result, it gives an insight to the breeder to use specific species to increase their genetic base.

葱属因其风味和药用价值而成为日常饮食中必不可少的作物，它们是高度异花授粉的作物，易于近交或连续自交，并且两年一次的作物周期在葱属改良中具有复杂性。然而，种间杂交有助于对害虫、疾病和非生物因素产生抗性的基因渗入，这可以最大限度地减少或消除植物保护剂的使用。此外，将新的代谢物和气味分子转移到可食用的葱属物种中可能有益于人类健康。它通过获得新的基因库来增加遗传多样性，并有助于葱属的遗传改良。在这种情况下，葱属的野生近缘种可用于引入抗性基因，如葱属有一个未开发的基因库。然而，了解物种兼容性是开始杂交计划的必要条件，也是基因渗入育种的一个重要方面。在这篇综述中，我们回顾了在葱属之间进行种间杂交以实现交叉兼容性和理想的性状渗入的尝试。因此，它为育种者提供了使用特定物种来增加其遗传基础的洞察力。
