A methodology for the determination of pollination requirements in Japanese plum-type hybrids is described, which combines field- and laboratory-pollinations and observations of pollen tubes under the fluorescence microscopy with the identification of S-genotypes by PCR and the monitoring of flowering for the selection of pollinizers.
