IN the ‘science’ of breeding racehorses, there are always many contraditions and random successes occuring through the most unlikely of matings.

You might not have expected a daughter of the 2007 Arc de Triomphe winner to be mated with the top sprinter and source of speed Caravaggio, to produce a top two-year-old filly but that is what Dylan Thomas’ daughter Arya Tara did with her progeny Agartha winning the Group 2 Debutante Stakes impressively last week.
