Breeding blueberries for a changing global environment: a review

Area of Science:

• Horticulture
• Plant Breeding
• Agricultural Science

Background:

• Blueberries are globally recognized health foods with high commercial value.
• Highbush blueberry cultivation has expanded into warmer, drier regions.
• Climate change, including temperature increases and erratic rainfall, poses future challenges to blueberry production.

Purpose of the Study:

• To explore advanced breeding strategies for blueberry adaptation to changing climates.
• To highlight the potential of marker-assisted breeding (MAB) and phenomics in fruit crop improvement.
• To address the limitations of traditional selection methods in identifying desirable genotypes.

Main Methods:

• Review of genetic variability within the blueberry gene pool.
• Discussion of marker-assisted breeding (MAB) applications.
• Exploration of phenomics for trait identification in plant breeding.

Main Results:

• Traditional blueberry breeding methods are slow and may not reveal all adaptive traits.
• Marker-assisted breeding (MAB) and phenomics can significantly improve selection efficiency.
• These technologies can accelerate the release of new blueberry cultivars adapted to challenging environments.

Conclusions:

• Advanced breeding techniques like MAB and phenomics are crucial for future blueberry cultivar development.
• Implementing these methods can help overcome climate-related challenges in blueberry production.
• Phenomics, while established in grain crops, offers untapped potential for fruit breeding programs.
