Exciting juveniles Ivawood, Faydhan and Richard Pankhurst feature among 92 entries for this year's £75,000 Group Two Champagne Stakes at Doncaster on September 13.
The trio are all prominent in the betting for next year's 2000 Guineas following impressive starts to their careers, with Ivawood having stormed to victory in the July Stakes at Newmarket earlier this month.
Faydhan posted a six-length victory on his debut for John Gosden at Haydock, while stable companion Richard Pankhurst clinched the Chesham Stakes at Royal Ascot.
Ivawood's trainer Richard Hannon is responsible for eight entries in all, with Kool Kompany, a Group Two winner in France and Ireland already this season, Norfolk Stakes hero Baitha Alga and Group Two Superlative Stakes scorer Estidhkaar also among a formidable team from the first-season handler.
A total of 18 entries from Aidan O'Brien include debut maiden winners Gleaneagles and East India, the regally-bred John F Kennedy and recent Group Three Anglesey Stakes scorer Dick Whittington.
Trainer Karl Burke has made three entries including Ayr debut winner Glenalmond, who is a full-brother to Group One-winning two-year-old Wootton Bassett.
Burke said: "We were very pleased with Glenalmond at Ayr. It's hard to know what he beat but the runner-up had previously finished second in a maiden that is working out well.
"The Acomb Stakes or Gimcrack Stakes at York are definitely possibilities for him now. He has got an entry in the Gimcrack, but I think the owner is keen to step up him up a furlong and we certainly think he will stay.
"Obviously, if he came through one of those races in good order then the Champagne Stakes will be on the agenda.
"He has a very nice pedigree, being a full-brother to Wootton Bassett, and is very much one for the future. Wootton Bassett had quite a hard time of it as a two-year-old, but Glenalmond won't and we think he will train on."
The Middleham handler has also entered Group Two Superlative Stakes fourth Natural Order and Toocoolforschool, who was third on debut in a six-furlong maiden at Nottingham on July 18.
"Natural Order ran very well to be fourth in the Superlative Stakes," said Burke.
"He is having a little break at the moment and will be out again at the end of August. We will see how he gets on there, but he would have to improve to go for another Group Two.
"Toocoolforschool is potentially a very nice horse and possibly goes for a maiden at York this weekend. It's early days yet but they are all potentially nice colts."
Charlie Appleby, successful in the 2013 Champagne Stakes with subsequent Breeders' Cup Juvenile Turf scorer Outstrip, has a quartet of contenders including Newmarket winner Zephorus and Hawkesbury, who posted a seven-length success in a Doncaster maiden.
Flaming Spear (Kevin Ryan) made an impressive start to his career with a decisive victory in a York maiden on July 12, while Aktabantay (Hugo Palmer) is also in contention at this stage.
