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.

Chilean cherry imports in Argentina hit 1,273 tons, setting a new record. Amid Chilean oversupply and steady premium demand, the market absorbs higher volumes without price collapse, raising questions about future balance and competition in the sector.

This is above the previous season’s figures (2023/24), in which 83 million boxes of cherries were produced, fewer than the 95 million boxes expected by the market. However, volumes of Santina are expected to double this season 175,353 tons, which could undoubtedly impact prices.

In the Andean-Patagonian temperate forest, alien species recruitment depends on predation, frugivory, seedling survival and functional traits. Seed size emerges as the key factor, with Prunus cerasus showing the highest invasive potential among the species studied in Patagonia.
