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.
Post-harvest Production Varieties

Manual harvesting of stalkless cherries reduces the time by 40-45% compared to manual harvesting of traditional cultivars; stalkless cherries are cultivars whose FRF value, when ripe, is 200-300 g compared to 450-900 for 'normal' cultivars.

According to the cherry yearbook recently published by iQonsulting, during the 2023/24 season, 413,979 tons of Chilean cherries were exported. For this latest season, the estimated value could exceed $3 billion FOB.

A genomic study identifies 17 HSP70 and HSP90 genes in sweet cherry and explains how they respond to heat and salinity. The results highlight key genes, including PavHSP90-5, that could support breeding of cultivars with resilience to climatic and environmental stress.

A study in southern Chile shows how mineral nutrition, especially the balance between nitrogen and phosphorus, may influence internal browning in Regina sweet cherries, postharvest quality and the fruit’s ability to withstand long storage periods for export markets.
