Testing of sweet cherry cultivars on chilling requirements for endodormancy breaking

Original language description

Temperate fruit species need to accumulate a cultivar-specific amount of a cold period (chill) to complete their life cycle during endodormancy and of a heat during ecodormancy. Without these periods they would not complete their development, flower properly in spring and produce less pollen, which would affect the fruit set and the overall harvest. Thus information on chilling requirement of sweet cherry cultivars is valuable information for growers. Totally 64 cherry cultivars was tested in the air-conditioned growth chamber in period from 2017 till 2023. Three main models (Dynamic Model, Chilling Hours Model and Utah Model) were compared. Results confirmed different chill requirements of evaluated cultivars. The lowest chilling requirement was assessed for cultivars ‘Adélka’ and ‘Koburska rana’, that are cultivars evaluated in the low chilling requirement category with chill hours (CH) below 500 calculated according the Chilling Hours Model. Cultivars ‘Kasandra’, ‘Kišiněvskaja’ and ‘Klecanska’ with chilling hour requirement in the range of 500 – 750 CH are also the only ones in the low – moderate chilling requirement category. 40 genotypes were evaluated In the category moderate – high requirement (750 - 1000 CH). In the high requirement category with chill hours 1000 - 1500 were classified 21 cultivars. Any cultivar was assessed for the category very high requirement (over 1500 CH).
