Summary Sweet cherry is a diploid tree species and its fruit skin has rich colours from yellow to blush dark red. The colour closely related anthocyanin biosynthesis mainly regulated at the transcriptional level by transcription factors that regulate expression of multiple structural genes. However, genetic molecular bases how these genes ultimately determine traits remain poorly understood. Here, our evidences identified R 2 3 MYB factor P av 10.1 involved in pathway determines sweet cherry. Interestingly, we three functional alleles gene causally leading different mature stage. Meanwhile, experimental results yeast two‐hybrid assays chromatin immunoprecipitation revealed might interact with proteins avb HLH WD 40, bind promoter regions ANS UFGT ; findings provided certain extent mechanistic insight into gene's functions. Additionally, confirmed reliable DNA marker select
