This research presents a summary of the observed winegrape phenological characteristics and trends. Thirteen wine grape accessions maintained in germplasm collection considered old, autochthonous and neglected genotypes at risk of extinction were analysed for their main phenological evolution. The weather data are recorded from 979 to 2023, and the phenological data were compared for the last 3-year period. Changes are usually greater at minimum temperatures than maximum temperatures, with an average study-year warming of .55°C during the growing season over the multi-year analyzed 970–2020. Results showed 5 to 4 days earlier budding, 8 to 23 days earlier flowering onset. 'Rară albă' genotypes, the advance for the beginning of flowering was 23 days earlier in 2023 and 2 days earlier in 2022, compared to the beginning recorded in 202 . The advancement of the phenological stages of the vine is similar in other countries with a continental climate and not only, and the risk of the extension of late frosts has increased.
