| Research Abstract |
We carried out self-pollination with young buds of citrus cultivars to produce eight groups of S1 seedlings homozygous for self-incompatibility gene(S1S1, S2S2,-, S11S11), and identified many cultivars with one of the eight S alleles by pollination with these homozygous seedlings. It was found that Hassaku(S4S5) and Satsuma mandarin(SfS4) are the hybrids of Kunenbo with S4 allele. With precociously flowered hybrid seedlings showing self-compatibility and-incompatibility, DNA markers for S gene were determined, but cloning of the S gene was not successful.
