Abstract

The genetic potential for freeze tolerance of peach remains unknown even though freezes are a major environmental limitation to stone fruit production.
In this study, we used the electrolyte leakage method as a simulation tool for assessing the susceptibility of peach fruitlets to late spring freezes.
We used fruitlets nearly a hundred accessions and cultivars of peach.
Our results showed that accessions such as Cumberland and cultivars such as White Lady, Scarletpearl, and Raritan Rose had an increased freeze tolerance compared to most accessions and commercial cultivars.
These results need to be confirmed with one more year of data, but these accessions and commercial cultivars are worth exploring as promising materials for breeding purposes.
