Susceptibility of 17 sweet cherry cultivars to rain induced fruit cracking was studied in the Belgrade region (Serbia) during a three-year period of 2008-2010. Testing of fruit cracking was done using cracking index by Christensen. In the cultivars tested were found significant differences in cracking index, fruit weight and soluble solid content. The highest susceptibility to rain induced fruit cracking showed cultivars Bigarreau Jaboulay, Primavera, Bing, and Merchant, while the least sensitive cultivars were Sue and Čarna. Based on cracking index, cherry cultivars were classified into four groups: low susceptible (less than 10), moderately susceptible (10-30), susceptible (30-50), and highly susceptible (greater than 50). Most cultivars (11) were susceptible and highly susceptible to fruit cracking. Correlations between cracking index, fruit weight, and soluble solids contents were low among different varities, but very strong among different harvest terms.
