| Summary: | One of the most common perennial legume grasses of Precarpathian, a valuable component of grass mixtures in improving natural hayfields and creating cultivated pastures is white clover (Trifolium repens L.). It tolerates trampling and grazing by animals, is more winter hardy, and by protein content do not concede to red clover and hybrid clover. Due to the ability of nitrogen fixation thanks to presence of nodule bacteria on its roots, the agrophysical, agrochemical and biological properties of the soil are improved. An important role in the formation of the productivity of white clover belongs to the variety, which is achieved by conducting selection work, the first and main stage of which is the study and evaluation of initial material.
The data of scientific research carried out on the experimental basis of Precarpathian Department of Scientific Research of the Institute of Agriculture of Carpathian Region of NAAS for 2021 are presented. The material for the study were 24 collection samples of white clover of various ecological and geographical origin. The initial evaluation of the collection material on the main economic and valuable features was carried out.
According to one-year data, the duration of the growing season of the studied samples was 126–134 days. The plant height was 20.4–29.4 cm, daily growth – 0.23–0.28 cm, leafiness of plants – 30.0–61.1 %. The yield of green mass on average for two mowes was 2.05‒3.10 kg/m2 and the yield of dry matter was 0.302–0.420 kg/m2. The highest yield of green mass had such samples as UJ 0600796 – 3.10 kg/m2, PFZ 00372 – 3.00 kg/m2, UJ 0600658 – 3.05 kg/m2, PFZ 02112 – 3.02 кg/m2 and dry matter ̶ UJ 0600691 – 0.404 kg/m2, UJ 0600796 – 0.420 kg/m2, PFZ 00372 – 0.417 kg/m2, PFZ 02314 – 0.410 kg/m2, UJ 0600658 – 0.414 kg/m2. The seed productivity of collection samples was from 9.80 to 14.50 g/m2. The analysis of the structure of the seed productivity showed, that the diameter of the head of the studied samples was from 19.5 to 28.0 cm, the number of flowers in one head – from 42.3 to 83.3 pcs, the number of seeds in one head – from 43.6 to 110.5 pcs, the weight of 1000 seeds – 0.55 – 0.78 g.
