Manifestarea heterozisului la hibrizi F1 de Salvia sclarea L.

22 hybrids F1 of Salvia sclarea L., were evaluated, which show heterosis in a series of quantitative characters, which directly influence productivity, at the same time being a valuable breeding material for the elaboration of few varieties of hybrid origin.
