Allele mining is a pathway to genomic selection that is in high demand to improve the crop features to fulfill the ever-increasing food demand, crop sustainability under changing global climate, and better economic out-turn in limited resources. Papaya is a tropical fruit crop, and the fruit is available throughout the year. The excellent health benefits of papaya fruit are a significant cause of increasing demand for fruit production worldwide. Selective breeding in papaya helped us to feature the key desirable consumer-driven fruit quality traits. However, underpinning the genomic loci linked to these traits is limited. Therefore, exploring the genetics of papaya using key allele variants of targeted fruit shape and fruit quality traits may help us shape the future fruit of papaya according to industry needs for ease of transportation, packing and mechanical picking and consumer demand for a better taste. Understanding the sensory profiling of papaya flesh (both red and yellow genotypes) will help us establish the precise phenotyping platform of secondary metabolites that develop the taste of papaya fruit. Understanding the vast potential of allele mining, collaborative allele mining efforts by discovering key allelic variants are required across crop research institutes focusing on papaya breeding in developing new cultivars. Therefore, precision phenotyping methods would help set up a standardized measurable platform for desirable fruit quality traits. Also, advanced statistical genetic tools embedded with core computational skills will help either re-visiting established genetic linkage maps or genome alignment by increasing the capacity of the reference genome that may have the ability to represent the red-and-yellow papaya types truly. That will entail linking the genotype-to-phenotype relationship and helping to establish the allele mining platform of targeted fruit quality traits. This book chapter examines the breeding concepts and strategies deployed over time, prospects of breeding design based on industry requirements and consumer-driven approaches and the correct applications of phenomics and genomic tools in finding key allelic variants for allele mining and its utilization in papaya molecular breeding.
