Harnessing genomic resources for passion fruit improvement: Progress and prospects

Area of Science:

• Horticultural science
• Plant breeding
• Genomics

Background:

• Passion fruit (Passiflora edulis) is a vital crop facing challenges with suboptimal on-farm productivity and declining vigor in existing cultivars.
• Despite breeding efforts, enhancing yield and stress resilience requires more efficient methods.

Purpose of the Study:

• To explore the integration of advanced genomics technologies into passion fruit breeding pipelines.
• To accelerate genetic gains and improve cultivar development for stable, enhanced yields.

Main Methods:

• Leveraging developed genomic resources: genome-wide markers, marker-trait associations, reference genomes, and resequencing data.
• Utilizing emerging approaches: genomic selection, speed breeding, and high-throughput phenotyping.

Main Results:

• Genomic tools are being deployed to enhance yield and desirable traits in passion fruit.
• Advanced techniques show potential for accelerating genetic gains in breeding programs.

Conclusions:

• Strategic use of diverse genetic resources and efficient delivery systems are crucial for maximizing genomic benefits.
• Overcoming technical and operational challenges is key to translating genomic advances into field-ready passion fruit cultivars.
