Abstract:
Self-incompatibility (S-) groups were determined using PCR based S-allele type analysis and self-fertility
was confirmed by pollinataion trials of sweet cherry advanced selections from the Agriculture
and Agri-Food Canada breeding program in Summerland, BC, Canada.
Four S-allele genotypes (S1S3,
S1S4, S3S4 and S2S4) were detected (PCR method can not differentiate S4 and A4'-pollen part mutant)
among twenty-one selections.
Ten selections were found to be self-fertile, four selections were likely
self-fertile where S4' is presumed.
