Researchers at Michigan State University conducted a study to identify the genes associated with tart cherry trees that bloom later in the season, aiming to address the challenges posed by climate change. Initially, they compared the DNA sequences of late-blooming tart cherry trees with those of peaches, a related species. However, they discovered significant genetic differences between the two species rather than similarities. Consequently, the team created the first annotated genome of the Montmorency tart cherry and identified the DNA segments responsible for each gene.
The researchers encountered unexpected complexities in the Montmorency tart cherry genome due to its allotetraploid nature, meaning it has four sets of chromosomes from at least two different species. The tart cherry is the result of a natural cross between the ground cherry (Prunus fruticosa) and the sweet cherry (Prunus avium) that likely occurred around two million years ago.

The genome sequencing provides valuable insights for researchers seeking to develop cherry trees that bloom later in the season and exhibit specific fruit traits such as color and firmness. By better understanding the genetic makeup of tart cherries, researchers can contribute to the cultivation of trees that can withstand variable spring weather and increase cherry production. The availability of the Montmorency tart cherry genome will significantly impact future research and breeding efforts worldwide in the tart cherry industry.

Dormancy, winter chill, cultivar and rootstock choice, pollination and climate-risk management shape sweet cherry yield and quality in Spain, from the Jerte Valley to Zaragoza, across high-value fresh-market orchards facing frost, heat, rain, cracking and yield risk.

The study compares MAP and controlled atmosphere storage for Rainier, Bing, Skeena and Sweetheart sweet cherries, assessing firmness, stem quality, weight loss and postharvest disorders to identify effective strategies for maintaining fruit quality for long-term storage.

Effective sweet cherry postharvest management protects the canopy, reduces heat stress and restores tree reserves. Balanced irrigation, selective summer pruning and targeted nutrition prepare trees for dormancy while supporting bloom, fruit set and next season’s crop.
