Expression for the seven marker genes allows accurate prediction of the bud dormancy stages in the late flowering cultivar ‘Fertard’ during two bud dormancy cycles. a Relative expressions were obtained by RT-qPCR and normalized by the expression of two reference constitutively expressed genes PavRPII and PavEF1. Data were obtained for two bud dormancy cycles: 2015/2016 (orange lines and symbols) and 2017/2018 (blue lines and symbols). b Evaluation of the dormancy status in ‘Fertard’ flower buds during the two seasons using the percentage of open flower buds (BBCH stage 53). c Predicted vs experimentally estimated bud stages. SRP: STRESS RESPONSIVE PROTEIN; TCX2: TESMIN/TSO1-like CXC 2; CSLG3: Cellulose Synthase like G3; GH127: Glycosyl Hydrolase 127; PP2C: Phosphatase 2C; UDP-GalT1: UDP-Galactose transporter 1; MEE9: maternal effect embryo arrest 9
