Sweet cherry cultivars from Czech Republic

Throughout the whole cherry season

 

Research and Breeding Institute of Pomology Holovousy Ltd.

 

  • Well-known cultivars are surely Kordia, Vanda and Těchlovan. Kordia is random seedling originated in 1968 in Czech Republic. At this time cherry breeding programme started in Holovousy. Cultivars Těchlovan and Vanda were bred as a crossing between Van and Kordia in 1973. 
  • Important breeder Ing. Jitka Blažková breeds sweet cherries for all her life more than 40 years.
  • More than 30 of cultivars have been registered or applied for registration in our country till now.
  • The emphasis was given on their fruits size, fruit firmness, good taste and reliable productivity.
  • Time of their ripening completely covers total cherry harvesting season since the first cherry week (´Adélka´ cv.) till the seventh one (´Vilma´ or ´Halka´ cvs.).
  • Their fruit size, being partly connected to the week of ripening, fluctuates between 24 to 30 mm of the fruit diameter or between 6.5 to 12 g of the weight. Some of them (´Helga´, ´Christiana´) are more resistant to fruit cracking and more productive than ´Kordia´. 
  • Particular choice of the cultivars for the growers depends on local climatic and soil condition and some of them are preferably recommended for large scale commercial growing.
