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.

The sweet cherry supply for 2024 remained in line with the average of the last five seasons, which saw an average production of about 100,000 tons per year. However, 2023 stood out as a negative year, with a production of only 93,000 tons, the lowest value in the last five years.

A low-quality plant will hardly be able to express its productive potential and if possible, it will have a high productive cost. This is the number one mistake when establishing a garden: it is important to be clear that a “good plant" is priceless.

Aragonese cherries are set to enter the Chinese market thanks to Orchard Fruit, a family business led by Menchu Guerrero. Since 2017, the company has followed a scientific and export-driven strategy, inspired by Chile’s model, to bring premium fruit to global markets.

An innovative study compares qPCR and dPCR to analyze genes linked to fruit cracking in cherries. Eight molecular markers were identified to support genetic improvement, early diagnosis and field strategies against cracking, a key challenge in cherry farming.
