Peach Jewels

Peach fruit texture type

Table of functional genotypes

Trait: Peach fruit texture – freestone vs. clingstone and melting flesh vs. non-melting flesh
Locus:  Freestone-Melting flesh (F-M) locus near the bottom of Prunus chromosome 4; controlled by endoPG genes at the locus
            (and thus also referred to as “endoPG locus” or F-M-endoPG locus)
Marker: Primary alleles: Simple PCR-based SCAR marker targeting small indels in the first intron of two adjacent endoPG genes (“endoPG-6”).
            Secondary alleles: SSR marker targeting a (CA)_n di-nucleotide microsatellite in the promoters of two adjacent endoPG genes
            (“endoPG-1-SSR”). This marker also distinguishes primary alleles, but can be readily PCR-multiplexed with the endoPG-6 marker
            for greater reliability
