Abstract: Vine damage caused by spring frosts remains one of the main factors threatening grapevine yields in Central European countries, such as Poland. April frosts that followed a very early and warm spring in 2024 caused massive damage to young shoots and primary buds after budburst. This study was conducted on vines of fifty cultivars belonging to Vitis vinifera , interspecific hybrids, and inter-intra- or intra-interspecific hybrids (classified by some sources as V. vinifera ), which were obtained via field collection. The aim of this study was to obtain primary results regarding the fertility of secondary, basal, and latent buds. The presence of inflorescences in these buds determines the ability to compensate for yield, i.e., produce a crop after damage to the primary buds. The tested cultivars, which were within the three groups mentioned above, differed significantly in their ability to compensate for yield. The majority of the analyzed V. vinifera cultivars were characterized by lower fertility in their secondary, basal, and latent buds and a reduced ability to compensate for yield after post-budburst freeze damage compared to interspecific hybrids and inter-intra- or intra-interspecific hybrids. Future research, with more comprehensive data collected over a longer period, will provide stronger suggestions for suitable cultivars in regions at risk of spring frost damage.
