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.

In Chile researcher studied the effect of foliar application of the biostimulant Retard Cherry® before leaf fall in cv. Regina and Sweetheart. The use of Retard Cherry® resulted in a 6-8 day delay of full flowering. However, the harvest date remained unchanged.

An increasing number of deformed cherries are discarded due to strict aesthetic standards imposed by retailers. This phenomenon, linked to climate change, reduces farmers’ profitability and increases food waste, threatening the sustainability of the entire supply chain.

Despite a high-quality and abundant harvest, cherry growers in the Pacific Northwest end the season with losses: labor shortages, high supermarket prices, and weak demand have strained producers in Oregon and Washington, two of the leading cherry regions in the US.
