Abstract

The article presents the data obtained on plant height and green mass productivity for three cuttings of alfalfa samples from a hybrid nursery of the first year of life established at the central experimental farm of CBSPARI in 2025. For two cuttings, the average height of plants in hybrid combinations S-3791, S-3793, S-3794, S-3795, S-3796, S-3797, S-3798, S-3799, S-3800, S-3801, S-3804 and S-3805 was 0.7-8.7 sm higher than the standard Tashkentskaya-1 variety (65.3 sm). The green mass productivity for the sum of three cuttings for the standard variety Tashkentskaya-1 was 338.0 g/plant, and for the hybrid combinations from 293.0 g/plant to 430.0 g/plant. The indicators for this trait in the hybrids S-3794 (k-1222 Parkent - selfed), S-3796 (k-1170 Kurganskaya x k-1289 Geok-Tepe), S-3799 (k- 1227 Zarkant x k-1113 Kyzyl-Ardinsky district), S-3800 (k-1227 Zarkant - selfed), S-3803 (k-1175 Novy Urganch x k-1349, Nukhur) and S-3806 (k-1349 Nukhur - selfed) exceeded the standard variety by 12.4-27.2%.
