Is your Thoroughbred bred to jump? 
Many Thoroughbred owners now know that the cross with an Irish Draught Horse is  the best way to insure Hybrid Vigor.  However,  if the mare is not from a talented line of jumpers the effort may not produce the results  one is hoping for.  The offspring will be better in the show ring than their thoroughbred ancestors, but will they ever win a grandprix?
  If it is accepted that the mare has a lot of influence on the offspring.  It would be reasonable to believe, therefore, that a Thoroughbred mare from a line of  breeding that has produced jumpers will produce a better competition horse than a mare with no line background of successful competition.  Therefore, it would make sense to check the background of your mare or the mare you intend to buy.  O'Leary's Irish Diamond has access to research on Thoroughbred jumping and eventing lines.
