Inheritance of economically important traits in common vetch hybrids (F1)

Abstract

The paper presents the results of a study on the true heterosis and the degree of dominance/ depression of traits (the number of pods and seeds per plant, plant height) in F1 common vetch hybrids. The highest phenotypic dominance and true heterosis of the pod (Htr.=151.5 %, hp=8.7) and seed number (Htr.=111.7 %, hp=6.7) per plant were observed in hybrid accession 13 (Mestnaya x VIR 217). Our correlation analysis revealed a strong direct correlation between seed productivity per plant and the number of seeds (r=0.93) and pods per plant (r=0.92), as well as between the number of seeds and the number of pods per plant (r=0.98).
