Abstract

Among the S-genotypes in sweet cherry, the highest frequency of selfincompatibility breakdown was found in S3S4 genotypes (>3% fruit set when selfpollinated). However, the frequency of breakdown (expressed as either fruit set or pollen tube growth rate) did not differ among cultivars within the same S-genotype combination. Depending on different temperatures from 10 to 25 °C, breakdown (expressed as unrestricted pollen tube growth) ranged from about 0 to 25 % in selfor cross-incompatible pollinations of all S-genotypes combinations. The S3S4 genotypes almost always had the highest breakdown frequency at all temperatures. However, no specific S-allele alone was associated with the increased incidence of self-incompatibility breakdown.
