AB  - In Serbia, alfalfa (Medicago sativa L.) is grown on about 140,000 ha, out of which 3–7% are intended for seed
production. Climatic factors (amount and distribution of precipitation) are the main determinants of alfalfa
seed yield. Average alfalfa seed yield in Serbia is about 250 kg ha-1, and seed production is characterized by
huge variation (15–800 kg ha-1). The most challenging year for seed production is the establishment year, i.e.,
the first year of plant life. To be successful on the market, new alfalfa varieties are selected for high forage
production, quality of forage, and persistence. However, outstanding seed-yield potential is also needed. Even
if breeding for seed yield is not prioritized, genetic variation among cultivars is known. In order to explore
genetic variation for alfalfa seed yield and its components in the establishment year, a trial with 400 accessions
was established at the experimental field of the Institute of Field and Vegetable Crops, Novi Sad, Serbia, on
May 21, 2018. The genotypes were tested in a partially replicated design. For the purpose of this study, we
extracted model best linear unbiased predictions (BLUPs) for 20 populations, which represent a part of the
European alfalfa core collection. The plot size was 6 m2
. Seed yield and its components were recorded for
each plot. The 2018 field season was not favorable for alfalfa seed production in Serbia, but the results clearly
demonstrate differences among varieties for total seed yield and its components in the establishment year.
Seed yields varied from 31.8 kg ha-1 for the variety ‘Tereza’ to 96.7 kg ha-1 for the variety ‘Etincelle’. Higher
seed yields were obtained with less dormant varieties (dormancy ratings 5–6), while lower yields were
recorded with more dormant varieties (dormancy ratings 3–4). Analyses showed that, even under unfavorable
conditions, genetic variation could be important for alfalfa seed production in the year of establishment.
