The first experiences with cherry breeding at the VSUO in Holouvosy in the Czech Republic date back to the late 1960s. The main variety selected from this programme is Kordia, which in recent years has become one of the world's leading varieties in the medium-late ripening period, mainly due to its high fruit quality standards.
The primary objectives of the WSUO programme are cherry quality (size, texture and colour), resistance to cracking and rot, shelf life and plant productivity. MAS technologies are used in the breeding programme for the early selection of genotypes on several traits: self-fertility, spring frost resistance, drought and climate change tolerance and low chilling requirements.
WSUO, besides Kordia, has commercially propagated 28 cherry varieties. The best known are Early Korvik, Christiana, Felicita, Irena, Justyna, Kasandra, Tamara, Techlovan, Tim and Vanda.
Below is the report of Lubor Zelený, cherry breeding project manager at WSUO in Holouvosy, presented at the workshop on cherry variety innovation at Macfrut 2023.

Pathogenicity tests showed that all isolated species could cause fruit infections, though with varying levels of aggressiveness. Among them, Diaporthe eres displayed the highest virulence followed by Fusarium incarnatum and Botryosphaeria dothidea.

From snowy Montana comes the new “FE” cherry, cold-hardy to -45°C and ideal for pies, wine, preserves, and fresh eating. Backed by 60 years of family-driven selection, it’s now available from HoneyberryUSA, a leader in American cold-hardy fruit farming.

A scientific study confirms native moths thrive best on cherry trees native to Massachusetts. Non-native species slow growth and raise mortality in larvae. Native trees are crucial for preserving biodiversity and supporting birds and insects in gardens and cities.

Researchers from Clemson University and Spain’s CITA discovered the genetic basis of sweetness and acidity in sweet cherries. With QTL mapping and haplotype analysis, breeders can now develop better-tasting, more stable varieties tailored to consumer preferences in Europe.
