Harnessing novel genomic resources and emerging breeding tools to fast-track genetic improvement in papaya
Horticultural plant journal, In Press
2025
Abstract
Papaya is a nutritionally valuable fruit crop cultivated globally in tropical and subtropical regions. Conventional breeding efforts have prioritized enhancing traits such as yield and fruit size, with notable success in developing high-yielding cultivars. However, other critical areas in papaya improvement, such as enhancing genetic diversity, improving disease resistance, optimizing post-harvest management, and addressing consumer preferences for fruit quality and flavor, have experienced relatively limited progress. Addressing these gaps is essential for meeting both production challenges and market demands. Achieving substantial genetic gains in these traits in the shortest timeframe will require integrating traditional breeding practices with emerging genomics tools. Over the past two decades, substantial advancements in papaya genomics have been achieved, resulting in resources including high-density genetic maps, high-quality reference genomes, and transcriptomic and resequencing datasets. These resources have been utilized to develop genome-wide markers and identify marker-trait associations, supporting the development of disease-resistant varieties and uncovering the genetics of consumer-preferred traits. By utilizing these resources in combination with innovative approaches such as genomic selection and speed breeding, sequence-based breeding approaches can significantly accelerate genetic gains in papaya. This enables the rapid development of elite (high-performance) papaya cultivars that meet both agronomic and consumer expectations.
