Twelve genotypes belonging to three alfalfa species (Medicago sativa L., Medicago media Pers, Medicago falcata L.) were assessed for inflorescence position on the plant (basal, medium and top flowers) and seed yield components in conditions of open pollination (polycross). The basal, medium and top inflorescences produced 6.9, 8.0 and 6.1 pods per inflorescence, respectively. Thses differences were highly significant. The respective inflorescences rendered 2.64, 2.89 and 2.39 seeds per pod. These differences were highly significant too. The following genotypes produced the largest numbers of pods at the different inflorescence strata: S-13 (9.4), S-11 (8.1), and S-15 (7.7) among the blue-flowered alfalfas, H-24 (7.6) among the hybrid alfalfas, and F-32 (4.7) among the yellow-flowered alfalfas. The two-year average number of pods and seeds per pod were 7.9 and 2.93, respectively, in the blue-flowered alfalfa genotypes, 7.2 and 2.66, respectively, in the hybrid alfalfa genotypes, and 4.5 and 1.87, respectively, in the yellow-flowered alfalfa genotypes.
