Abstract: 

In order to investigate genetic diversity in sainfoin (Onobrychis vicifolia) for seed yield and related traits in 36 foreign and Iranian ecotypes, an experiment was conducted using a square lattice design with two replications. Analysis of variance revealed significant genetic diversity among ecotypes as to some of the traits. Significant and positive correlation was observed between seed yield and biomass. Plant height, biomass and thousand seed weight explained about 64 percent of seed yield variation. Direct effect of biomass on seed yield and indirect effect of plant height through biomass was high. Therefore, biomass could be used as an effective variable for selection of high seed yielding ecotypes in plant breeding programs.
