The article presents preliminary results of breeding work with white clover in the Precarpathian Department of Scientific Research of the Institute of Agriculture of the Carpathian Region of NAAS of Ukraine. The importance of white clover as one of the valuable perennial legume fodder grasses is shown. The experimental part of the work was conducted in field and laboratory conditions during 2021–2022. 24 collection samples of white clover of different ecological and geographical origin were studied. The main goal of the study was to select the best samples with high fodder and seed productivity, which can be used as starting material in further breeding work with this plant to create new highly productive varieties. It is shown that the formation of fodder and seed productivity of white clover depends on the hydrothermal conditions of the region during the growing season. On the basis of two-year data, it was established that the highest yield of green mass during hay way of use, had such samples as PFZ 00483 – 3.20 kg/m2, PFZ 02112 – 3.14 kg/m2, PFZ 00650 – 3.00 kg/m2, PFZ 00372 – 3.02 kg/m2, dry matter PFZ 02110 – 0.410 kg/m2, PFZ 00483 – 0.415 kg/m2, PFZ 00372 – 0.412 kg/m2, PFZ 02314 – 0.408 kg/m2, PFZ 00650 – 0.409 kg/m2. The highest seed yield was provided by three samples, namely PFZ 00483 – 13.7 g/m2, PFZ 00142 – 13.6 g/m2, PFZ 01308 – 13.9 g/m2 with a standard seed yield of 11.3 g/m2.
