Self-(in)compatibility in apricot germplasm is controlled by two major loci, S and M.

ABSTRACT:

Background

Apricot (Prunus armeniaca L.) exhibits a gametophytic self-incompatibility (GSI) system and it is mostly considered as a self-incompatible species though numerous self-compatible exceptions occur. These are mainly linked to the mutated S _C-haplotype carrying an insertion in the S-locus F-box gene that leads to a truncated protein. However, two S-locus unlinked pollen-part mutations (PPMs) termed m and m' have also been reported to confer self-compatibility (SC) in the apricot cultivars 'Canino' and 'Katy', respectively. This work was aimed to explore whether other additional mutations might explain SC in apricot as well.

Results

A set of 67 cultivars/accessions with different geographic origins were analyzed by PCR-screening of the S- and M-loci genotyp
