The study aimed at estimating variance components of racing ability traits in Minahasa racehorses as a contribution to defining the breeding value for this population. Data were provided by Indonesian Horse Racing Assosiate/PORDASI (1) contained more than 150 placings at finish by horses running in 907 races from 2010 to 2017. Age of horses ranged from 2 to 7+ years, and the distances were from 600 to 1800 m. Speed of horses was derived from the distance of racetrack in the racing time of the winner due to only the horse wins finish time was recorded. Horses were from stables, from private breeders and from foreign breeding. Speed and Variance components were estimated by the descriptive and animal genetics measurement method. Statistical analysis accounted for fixed effects of year, age, race, sex and weight carried, and for the random effects of rider, permanent environment, and animal additive genetics. Speed rate was 14.62 m/s to 15.45 m/s or around 66 km/h (approx.) and heritability coefficients were 0.22 to 0.82 and repeatability 0.16 to 0.69, respectively. The highest breeding value (PBV) = 0.09 m/s of male H and MPPA (Most Probable Producing Ability) in the population = 0.19 m/s (individual B010) where the average MPPA value of the entire population is = 0.0239 m/s.
