Abstract. It is presented the results of examination of breeding samples of perennial clover (meadow, white and hybrid) and birdsfoot trefoil in competitive tests. Over two cycles of the research tetraploid ultra early maturing variety samples No 416, No 404, SGP-7, and Mars x R2S were selected with the productivity of green mass of 50–53 t/ha, of dry matter – 10.6–11.3 t/ha and with the crude protein yield of 1.65–1.70 t/ha. These values were close to those of the standard ‘VIK 84’, but the samples reached the cut maturity earlier by 6–9 days. Early maturing forms TOS-3 and TOS-4 exceeded the standard by 5–7% in green matter productivity (54–55 t/ha). Variety-microbial system No 63+KR-2 had the productivity of green mass of 54.1 t/ha, of dry matter – 11.8 t/ha, of crude protein – 1.73 t/ha. Among the diploid numbers, No 1217 was the best, which is higher than the standard ‘VIK 77’ in the yield of green mass by 15%, of dry matter – by 13%, of the accumulation of crude protein – by 12%. Variety-microbial systems VIK 7 + KS-18 and Topaz + KS-7 and ultra-early maturing samples M3R and No 177 were similar to the standard ‘VIK 77’ in productivity but had a shorter vegetation period (on 4–16 days). Among the hybrids of white clover, samples F7 Kiwi x Espanso, F4 Volat x Gomel’sky, F4 Titan x Gigant and Lugovik variety exceeded the standard ‘VIK 70’ in productivity of green mass and dry matter by 19.1–36.2% and 27.4–45.2%, respectively. The best samples of hybrid clover SGP-2, Krasavik, and Tetra Latvia exceeded the standard in green and dry matter productivity and crude protein yield by 7.1–12.7%, 13.4–24.4% and 11.4–21.1%, respectively. The perspective samples of birdsfoot trefoil SGP-6 and SGP-13 exceeded the standard by 23 and 19% in green and dry matter productivity.
