The selection committee of Foal Auction Prinsjesdag also traveled across town and country this year to select the best foals for the show jumping and dressage auction on Tuesday 13 and Wednesday 14 September. Even foals from the famous and sought-after lines of Usha van 't Roosakker and McLain Ward's Olympian Sapphire or the Van 't Merelsnest breeding are again part of the show jumping collection this year.

The colts come from the line of the world famous mare Usha van 't Roosakker this year Quantum of the Bishop (Untouched x Elvis ter Putte) and Quando van den Bishop (Harley VDL x Stakkato).

Quantum van den Bisschop is one of the few descendants of the recently deceased Untouched, who belonged to one of the greatest jumping talents in the world under Ben Maher at the age of nine. In addition, Quantum was bred out of the young, promising mare Mevita van den Bisschop, the half-sister of the international show jumping talents Josephine van den Bisschop (Alberto Zorzi), Isaac van den Bisschop (Hansueli Sprunger) and Jackson van den Bisschop (Sabrina van Rijswijk). Great-granddam Evita van 't Roosakker is a direct daughter of Usha van 't Roosakker and is therefore the full sister of Emperio van 't Roosakker (Alexandra Crown) and Equador van 't Roosakker (Frédéric David) and the half-sister of the famous Cella ( Ben Maher) and the promising young stallion George Z.
Via the mare Mandy van den Bisschop, Quando van den Bisschop goes directly back to Josephine van den Bisschop, who already jumps at international level at the age of seven under Alberto Zorzi – stable rider of Jan Tops. The great-granddam of Quando van den Bisschop is Evita van 't Roosakker, the Nabab de Rêve daughter from Usha van 't Roosakker.

The colts Qionno van 't Merelsnest (Kannan x Nabab de Rêve) and Quizano van 't Merelsnest (Diamant de Semilly x Kannan) represent this year the famous strain of Sapphire (McLain Ward) and Glasgow van 't Merelsnest (Jur Vrieling).

Qionno van 't Merelsnest descends from the talented mare Latina van 't Merelsnest who goes back to Wendelina van 't Merelsnest via Indi Blue-W van 't Merelsnest. This mare jumped at international 1.50m level herself, is the full sister of McLain Wards Sapphire and produced Glasgow van 't Merelsnest and Edjaz van 't Merelsnest (Ward De Bie) among others.
Quizano van 't Merelsnest has a pedigree to dream of with Diamant de Semilly, Kannan, Mr. Blue, Lord Z and Darco consecutively. Ultimately, Quizano's pedigree also goes back to the line of the two-time gold Olympian Sapphire.

The bloodlines of the Olympic finalists in show jumping in Rio de Janeiro and the auction collection of Foal Auction Prinsjesdag have many similarities. For example, Prinsjesdag offers a colt out of the three-quarter sister of Dejavu (Bassem Hassan Mohammed), a filly out of the half-sister of Emerald (Harrie Smolders) and a colt out of the direct line of Bonne Chance CW (Janika Sprunger).

The colt foal Qui a Vu van 't Merelsnest is a genetically very striking specimen. His sire Vigo d'Arsouilles was the 2010 World Champion under Philippe Le Jeune and his dam is Lacoste van de Bucxtale – a daughter of the Heartbreaker son Zambesi. This makes Lacoste a three-quarter sister of the Heartbreaker son Dejavu, who convincingly qualified for the individual final of the Olympic Games in Rio de Janeiro under Bassem Hassan Mohammed. Olympian Zilverstar T (Nicola Philippaerts) also comes from this direct dam line.
The filly is also unique quartina DC – a daughter of the foundation sire Comme Il Faut out of the Nabab de Rêve daughter Intense van 't Meulenhof. The mother of Quartina DC is none other than the half-sister of Emerald, who will compete with Harrie Smolders for individual medal of honor on Friday.
Levisto Blue RV Z is a colt by Levisto Z x Mr. Blue and is closely related to Janika Sprunger's topper Bonne Chance CW – also auctioned at Foal Auction Prinsjesdag. Levisto Blue's great-granddam Kalista – full sister of Audi's Jikke – is the granddam of Bonne Chance CW, who also qualified for the individual final. Unfortunately, Bonne Chance CW will not be allowed to start as three other Swiss riders were also qualified. According to the regulations, only three combinations per country are allowed to start in the final.

In addition, Foal Auction Prinsjesdag selected two offspring of Olympic finalists. The colt foal Vegas is a son of Maikel van der Vleutens two-time Olympian Verdi out of a Heartbreaker dam. Although things did not go as hoped for the Dutch team, Maikel van der Vleuten and Verdi did not miss a beat. With only two time errors, the foundation sire Verdi qualified for the Olympic final. Four years ago in London, Verdi also entered the last day without jumping errors. A very special colt is also Quest SZ – one of the very few descendants of the high-profile Quabri de l'Isle. The beautiful dark chestnut of Pedro Veniss jumped phenomenal every day in Rio and convincingly qualified for the battle for the individual medals.

With three offspring in the individual final, Cornet Obolensky and Kannan are the main suppliers in Rio de Janeiro. Foal Auction Prinsjesdag offers no fewer than five foals from Cornet Obolensky and two direct offspring from Kannan. Kannan is also represented several times in the dam line of the Prinsjesdag foals. In Barron (Lucy Davis) and Fit For Fun (Luciana Diniz) For Pleasure produces two direct offspring for the final and with Fine Lady (Eric Lamaze), First Choice (Yann Candele) and Fibonacci (Meredith Michaels-Beerbaum) three grandchildren. Prinsjesdag has included no fewer than four direct descendants of the legendary For Pleasure in its collection.
