Abstract :The S-genotypes of 63 wild-growing Turkish apricots insert ignore into journalissuearticles values(Prunus armeniaca L.); were determined by PCR amplification of the S-RNase intron regions and SFB gene in order to characterise their sexual insert ignore into journalissuearticles values(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 insert ignore into journalissuearticles values(provisionally labelled SX and SY); were identified in the genotypes. S2 was the most frequent S-allele in the tested germplasm insert ignore into journalissuearticles values(occurred in 19 accessions);, followed by S8 insert ignore into journalissuearticles values(17);, S19 insert ignore into journalissuearticles values(16);, S3 insert ignore into journalissuearticles values(13);, S12 insert ignore into journalissuearticles values(11);, S6 insert ignore into journalissuearticles values(10);, and S7 insert ignore into journalissuearticles values(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.
