Abstract
Apricot (Prunus armeniaca L.) exhibits a gametophytic self-incompatibility (GSI) system.
In apricot plantations, self-incompatibility (SI) is an important concern due to its impact onto production regularity.
In order to solve this issue, molecular techniques are used to determine self-incompatibility in apricot accessions.
In this context, SI was studied in a worldwide core collection of 168 apricot accessions coming from different geographic areas.
The PCR amplification focused on both S-locus, targeting the genes S-RNase and SFB, and M-locus with different primer combinations.
Up to 16 S-alleles were detected attesting the large variability of the S-locus within the studied apricot germplasm.
The distribution of the apricot S-alleles confirmed the species’ domestication and diffusion history.
The knowledge of incompatibility relationships among apricot accessions can be a highly valuable tool for the development of future breeding programs by selecting the appropriate parents and for efficient orchard design by planting a combination of self-compatible and inter-compatible accessions.
