GENOTYPING KOREAN APPLE CULTIVARS FOR SELF-INCOMPATIBILITY USING PCR AND CROSS-POLLINATION

Growers of Korean apple cultivars have known that fruit bearing requires cross-pollination.
To determine the cross-compatibility of cultivars, we identified the self-incompatibility alleles using PCR-based markers and cross-pollination tests in the field.
S-genotypes were determined as follows: ‘Hongro’ and ‘Saenara’ are S₁S₃, ‘Gamhong’ and ‘Manbok’ are S₁S₉, ‘Seokwang’ is S₃S₅, and ‘Sunhong’, ‘Seohong’, ‘Chukwang’ and ‘Hwahong’ are S₃S₉. Our results support the view that apples are fully compatible when both S-alleles differ and semi-compatible when they carry one different and one identical allele.
