Abstract

Aim. Research and evaluation of hybrid populations of (F3) alfalfa according to main agronomic characteristics for further use in breeding under conditions of high soil acidity. Methods. The field (phenological observations and records, hibryd analysis), laboratory (seed productivity accounting), mathematical-statistical (objective evaluation of obtained experimental data). Results. According to the research results of hybrid populations (F3) selected genotypes are tolerant to soil acidity with a relatively high forage and seed productivity, exceeding the standard sort of cyanosis on these indicators by 5–20 %. Conclusions. The evaluation has been performed and the promising starting material has been selected for four years planting alfalfa breeding (hybrid populations F3), which can provide a relatively high fee of dry matter (1.2–1.37 kg/m2) and seed yield (37.4–46.9) due to high soil acidity (pH 5.2–5.3).

Keywords: alfalfa, soil acidity, seed yield, dry matter.
