The purpose of the study is to study the diversity of manifestations of adaptability, productivity and quality traits and the selection of stress-tolerant and resistant forms and clones. Overwintering conditions were not extreme, which contributed to the preservation of up to 90% of buds. The technical forms 58-21-31, Skoda, 56-62-39 and 58-12-6 were distinguished. Among the varieties and forms of the table group, the control variety Vostorg and the form 59-24-23 were distinguished. According to the level of manifestation of the pathogen resistance trait in the conditions of the 2024 vegetation and against the background of an integrated protection system not lower than relative (6 points on a 9-point scale of resistance), most of the studied technical group of grape varieties and forms were distinguished. Promising seedlings were selected according to the level of manifestation of the main traits of breeding interest. 17 seedlings were selected that stand out in terms of productivity, pathogen resistance and quality traits. The determination of the prospects of the experimental varieties and forms was carried out using comparative analysis with a modular variety. A comparison was used with 14 traits with an optimal level of manifestation for technical varieties and 16 for table varieties. Promising varieties and forms were selected that stand out in most points of the modular variety in the conditions of the 2024 vegetation. The transfer of clones of the Sukholimanskyi white variety from the Kherson region and the study of their P1 in Odessa conditions was successfully completed. Many years of research into clones of the Sukholymanskyi white variety resulted in the selection of four clones that are best in terms of yield and quality of wine Product Description popup.authors Burhelia Nadiia Ye.
