The UK currently has limited success at producing show jumping horses of international standard (WBFSH, 2002). For improvement to occur a greater understanding of the population dynamics of the show jumping population is required

A selected group of progeny (n=304) sired by elite show jumping stallions was examined. Elite sires were defined as those that were ranked 1-10 in the 2001 Sport Horse Annual (British Horse Database, 2000) by total lifetime earnings of progeny competing in 2000. Comparative analysis was conducted with all competing show jumping horses (n=22421) in 2000 (British Horse Database, 2000). Data collected comprised of total lifetime money won at show jumping, total lifetime points won at eventing and dressage. Descriptive statistics were produced for each data set (Table 1). Product Moment Correlations were performed for all discipline areas (Table 2). Data transformation was applied using LOG+1(Hassenstein, Roehe and Kalm, 1996) to account for the skewness in all data sets.
