Correspondence between SOC1 Genotypes and Time of Endodormancy Break in Peach (Prunus persica L. Batsch) Cultivars

Knowledge of dormancy traits are important in peach breeding. Traditional method selection seedlings takes a long time because the juvenile period plants; therefore, novel application marker assisted methods needed to accelerate this work. The aims study were test extent variability PpSOC1 gene among 16 cultivars and establish whether SOC1 can be used as functional for timing endodormancy break based on 14-year phenology evaluation covering nine consecutive phases, from string stage ripening. Based an SSR motif SOC1, three allele categories detected: one cultivar was heterozygous (203/209), while five 15 homozygous carried 203 bp remainder characterized with 218 bp. There significant correlations between alleles various strongest being observed at stage, marking end endodormancy. At explained 82.6% phenotypic variance; reached 11.7 days earlier than those allele. This finding makes screening valuable
