Susceptibility of 15 sweet cherry cultivars to rain induced fruit cracking was studied in the region of Macva (western Serbia, along the Sava river) during a three-year period (2008-2010). Testing of fruit cracking was done using cracking index by Christensen and also by counting natural cracked fruits in orchard. In the cultivars tested significant differences in cracking index, natural cracking, fruit weight and soluble solids content were found. The three-year average fruit cracking index had the lowest value in the cultivar Chelan (15.3) and the highest one in cultivar Summer Sun (63.9). Natural fruit cracking varied from 9.1% (Chelan) to 81.0% (Skeena). Based on the cracking index, cherry cultivars were classified into three groups: moderately susceptible (4 cultivars) susceptible (8 culativars) and highly susceptible (3 cultivars). The highest susceptibility to rain induced fruit cracking showed cultivars Summersun, Skeena, and Cristalina, while the least sensitive cultivars were Chelan and Regina.
