ABSTRACT
Allele mining represents an advanced and refined method for analyzing naturally existing allelic variations within candidate genes, which play an important role in governing significant traits. In order to enhance the genetic capacity of economically valuable characteristics, it is necessary to focus on and re-explore existing genomic tools, aiming to harness new alleles from genetic resources. This can be achieved by identifying advantageous alleles within wild relatives and integrating them into cultivated varieties through introgression. This capacity would prove valuable in providing plant breeders with direct entry to essential alleles that bestow enhanced yield, nutrient efficiency, and bolster resistance to both biotic and abiotic stresses. In Alliums, very limited sequence data is available within public databases, so it is important to use available genomic information, which is crucial for discovering and extracting new and exceptional alleles. These alleles can then be appropriately applied to create enhanced cultivars through breeding efforts. In this chapter, we have presented the most current information regarding allele mining aimed at enhancing the genetics of Allium crops.
