Highlights • Herbaceous peony pollen could be sufficiently stored at 4 °C for hand-pollination among cultivars having non-synchronized flowering in a season according to measurement results of viability combination with verification results by hybridization.• All of the herbaceous peony pollen stored at −20 °C can be efficiently applied to pollination in the succeeding seasons according to measurement results of viability combination with verification results by hybridization.• I2-KI staining method may be more convenient and reliable compared with in vitro germination test in herbaceous peony according to measurement results of viability combination with verification results by hybridization.
