For the next four days World Breeding News for Sport Horses will be reporting as the action unfolds from one of the world's most iconic showjumping arenas in Spruce Meadows, Calgary, including the BMO Nations Cup (Saturday), and Sunday's CP International Grand Prix presented by Rolex.

This latter class will see Germany's Gerrit Nieberg attempt to pocket the $500,000 Rolex bonus having already won the CHIO Aachen Grand Prix that forms part of the Rolex Grand Slam series.

Eyes will, of course, focus on the breeding of participating horses, especially the descendants of the most represented sire, grandsire and great-grandsire here at Spruce Meadows, the legendary Quidam de Revel. The Masters' entry list includes two horses sired by Quidam – Quel Homme de Hus (out of P-Hawaii x Candillo) and Quilano Denfer (Salina IV x Cento) – plus 18 others (17.47%) of which he's either the grandsire or great-grandsire. This doesn't include an additional seven horses descended from Quidam's own sire, Jalisco B – all via the brilliant broodmare Fragance de Chalus – providing a very relevant gender equality perspective.
