Frost tolerance is a very important for plant survival during critical periods. Different species and varieties may have different damages at the same temperature and phenological degree, and this depends on the previous weather conditions and resistance to cold temperatures before the onset to frost. The sensitivity of fruit trees to low temperatures is related to genetic bases, as well as the condition of the tree and its physiological condition. There are many methods to combat injuries from low temperatures. Passive methods have a preventive effect for a longer period of time, while active methods are temporary and require work, and agronomists are recommended to use passive protection methods available to them, since they do not require large expenditures of energy and resources. Choosing varieties that bloom late reduces the risk of damage from late spring frosts. It is also important to choose varieties that are more resistant to low temperatures. The apple is one of the most represented fruit species in the world with more than 6 000 different varieties. Determining the percentage of bud susceptibility of ten domesticated apple cultivars to low temperatures resulted in the following values: ‘Škrobotelj’ 81,33%, ‘Roter Boskop’ 58%, ‘Damason Renette’ 52%, ‘Debela’ 28,67%, ‘Herberts Renette’ 78%, ‘Lesans Kalvill’ 56,67%, ‘Sternrenette’ 83,33%, ‘Trijerska jabukovača’ 52%, ‘Wagener’ 82% and ‘Zuccalmaglio’ 38,67%. The most resistant varieties was ‘Debela’ with the lowest 28.67% of frost damaged buds and ‘Zuccalmaglio' with 38,67%.
