| description | Knowledge of dormancy traits are important in peach breeding. Traditional method selection of seedlings takes a long time because of the juvenile period of plants; therefore, novel application of marker assisted selection methods are needed to accelerate this work. The aims of this study were to test the extent of variability in the <i>Pp</i><i>SOC1</i> gene among 16 peach cultivars and to establish whether the variability of <i>SOC1</i> can be used as a functional marker for the timing of endodormancy break based on a 14-year phenology evaluation covering nine consecutive phenology phases, from string stage to ripening. Based on an SSR motif of <i>SOC1</i>, three allele categories were detected: one peach cultivar was heterozygous (203/209), while five of the 15 homozygous cultivars carried a 203 bp allele and the remainder were characterized with 218 bp. There were significant correlations between the <i>Pp</i><i>SOC1</i> alleles and the various phenology phases, the strongest one being observed at the string stage, marking the end of endodormancy. At this stage, <i>Pp</i><i>SOC1</i> explained 82.6% of the phenotypic variance; cultivars with the 203 allele reached the string stage 11.7 days earlier than those with 218 bp allele. This finding makes the <i>Pp</i><i>SOC1</i> screening a valuable method in breeding. |
