Abstract

The S-genotypes of 63 wild-growing Turkish apricots (Prunus armeniaca L.) were determined by PCR amplification of the S-RNase intron regions and SFB gene in order to characterise their sexual (in)compatibility phenotype. We determined the complete S-genotype of 63 wild-grown apricot accessions that originated in the Erzincan region. Ten previously described and 2 new S-alleles (provisionally labelled SX and SY) were identified in the genotypes. S2 was the most frequent S-allele in the tested germplasm (occurred in 19 accessions), followed by S8(17), S19(16), S3 (13), S12(11), S6(10), and S7 (10); while S9-, S11-, and S13-alleles were found in 8 accessions. A total of 36 different S-genotypes were assigned to the tested accessions. The SC-allele responsible for self-compatibility in apricot was not present, indicating that all accessions are self-incompatible. The analysis of S-allele frequencies allowed us to conclude the close relationship of wild-grown and cultivated apricots in Turkey and helped to raise hypotheses to explain high occurrences of S2- and S8-alleles.
