Resumo: This study aimed to estimate genetic parameters for jumping measures in the Brazilian Sport Horses breed, looking to see which jump characteristics can be evaluated early and that present favorable genetic correlations (ϒg) with measures of later sports performance. Data were available for the results of jumping competitions on the Brazilian Sport Horses. Two traits were calculated: Classification (CLASS) of the animal (taking into consideration obstacle height, number of competitors, type of competition (regional, national, international) and final score (SCOREF) taking into consideration the weight of the competition, height of the obstacles and score for the placement and type of event. Heritabilities were low for the full database (0.00 and 0.07 for CLASS and SCOREF, respectively), but higher when only young horses were considered (0.09 and 0.67, respectively). Genetic correlations between these traits and subjective functional traits (using a scale of 0 to 10) measured at stallion approval for reproduction showed that Power was favorable for indirect selection for both traits (-0.85 for CLASS and 1.00 for SCOREF). Jump also showed a favorable correlation for SCOREF (0.53) but unfavorable for CLASS (1.00). Considering the importance of Temperament and the absence of unfavorable genetic correlations between it and competition results it was concluded that this trait can be maintained among the selection objectives of Brazilian Sport Horses. Suggestions are made for further genetic studies with this breed, and possible modifications in the evaluation regulations to improve data quality. Keywords: competition; final score; genetic correlations; heritability; temperament

Keywords: competition; final score; genetic correlations; heritability; temperamentEste estudo estimou parâmetros genéticos para avaliações de salto em cavalos da raça Brasileiro de Hipismo, buscando características passíveis de serem avaliadas precocemente e que estejam geneticamente correlacionadas (ϒg) com resultados posteriores em competições esportivas. Para os resultados de competições de salto duas características foram consideradas: Classificação (CLASS) do animal (considerando alturas dos obstáculos; número de competidores; tipo de competição: regional, nacional ou internacional) e escore final (SCOREF) (considerando peso da competição, altura dos obstáculos e escore para a colocação e tipo de evento). Herdabilidades foram baixas (0,00 e 0,07 para CLASS e SCOREF, respectivamente) quando o banco de dados foi considerado como um todo. Foram mais elevadas quando apenas a categoria Cavalos Novos foi considerada (0,09 e 0,67, respectivamente). Correlações genéticas entre estas características e avaliações funcionais subjetivas (em escala de 0 a 10) tomadas em aprovações de garanhões para reprodução mostraram relação genética favorável à seleção indireta entre Potência e resultados de competição (-0,84 para CLASS e 1,00 para SCOREF). Salto também apresentou correlação favorável com SCOREF (0,53), porém desfavorável com CLASS (1,00). Considerando a importância do Temperamento e ausência de correlações genéticas desfavoráveis desta com resultados de competição, conclui-se que esta característica deve ser mantida entre os objetivos de seleção de cavalos Brasileiro de Hipismo. Sugestões de estudos genéticos futuros para a raça e para possíveis modificações no regulamento das avaliações, foram feitas visando a melhoria da qualidade dos dados.
