Özet
Self-incompatibility plays an important role in the fertilization of fruit species such as apricot. Apricot (Prunus armeniaca L.) shows gametophytic self-incompatibility, which is controlled by a multi-allelic S-locus. In this study, S-alleles of 77 F-1 progenies derived from Paviot, which is one of the French local cultivars, and Kabaasi, one of the most important Turkish dried apricot cultivars, parents were identified by S-RNase intron regions polymerase chain reaction (PCR) amplification and DNA sequencing. The results from the S-allele PCR analysis revealed that the Paviot female parent had an ScS2 genotype and the Kabaasi male parent had S1S9 alleles. Forty-three of the F-1 progenies showed self-compatibility allele (S-c) by having either ScS9 or ScS1 alleles. Thirty-four of the F-1 progenies were self-incompatible by having either S2S1 or S2S9 alleles. The distributions of detected alleles in F-1 progenies were determined as follows: ScS1 31.2%, S1S2 27.3%, ScS9 24.7% and S2S9 16.8%. The results from the study are relevant for the data obtained in apricot breeding programmes in the selection of crossing combinations and in the establishment of commercial orchards.
