N2 - ABSTRACT: Young horse results of conformation and gaits were studied for their heritability and genetic correlation to future dressage competition results, to assess their value as young horse indicator traits. The young horse gait- and conformation scores generally had higher heritabilities (0.13˗0.48) than the breeding goal trait of dressage competition results (0.16). Young horse results showed medium high to high genetic correlations to dressage competition results (0.32˗0.91) where most recorded young horse gait- and conformation scores contributed with considerable information to future dressage competition results. If considering both accuracy of each young horse trait and genetic correlation to dressage competition results, as rg×rIA, the best young horse indicator traits for future performance were capacity, trot, canter, and rideability, all under own rider. Most important conformation traits were topline, loose trot, elasticity of gaits, and overall conformation.
