Edelmira produced a most impressive performance in the Irish Stallion Farms European Breeders Fund Give Thanks Stakes at Cork.

Unraced as a two-year-old and a good winner of her maiden at Tipperary in April, the Dermot Weld-trained filly was only sixth to Venus De Milo - who won this race 12 months ago - when favourite for the Munster Oaks over course and distance last time out.

She showed that running to be all wrong as Pat Smullen produced her to swamp the field at the furlong pole, powering clear to beat Dark Crusader by three and a quarter lengths for Group Three honours, with Shell House in third.

Tarana was sent off the 9-4 favourite and got to the front at the halfway marker from her wide draw, but while she had a clear advantage three furlongs out her exertions began to tell although she kept on to be fourth.

Weld's son Kris said of the Aga Khan-owned 6-1 winner: "It was disappointing the last day when conditions were all against her, (soft) ground is the key to her.

"She quickened up nicely today and she'll run in a Group Two at Longchamp on Arc weekend for fillies and mares (Prix de Royallieu) - she'll more than likely get her ground there."

Smullen said: "I was adamant after the last day that she couldn't let herself down on the firm ground. She showed the turn of foot today she showed at Tipperary. She's a smart filly, but ground dependent.

"I was very impressed with the way she picked up and all these Aga Khan-type fillies seem to improve."

The Ger Lyons-trained Roheryn was a significant non-runner due to the rain-softened ground.

Lyons had earlier seen Brendan Brackan justify short-priced favouritism in the Listed Platinum Stakes.

In a race depleted by four non-runners, the Group Three winner controlled matters from the front in the hands of Colin Keane.

Running for the first time in the colours of new owners Qatar Racing, the 4-9 market leader was briefly threatened by Witches Brew but in the end proved too strong and was good value for a three and a half length call.

Lyons said: "I thought he was better going right-handed with a tiny bit of juice, but not firm. If he had that juice, I think he'd have held on in the Ballycorus Stakes (narrowly beaten in third). Colin said he was just idling in front.

"It's a very important win, as I asked Sheikh Fahad to buy him back at the sales.

"He'll run in the Desmond Stakes at Leopardstown and he'll go pot hunting for his new crew.

"He has some really fancy entries and they are going to have fun with him.

"He's a good horse, a rock-solid Group Three horse, but we'll need all the luck in the world when he steps up.

"I'd like to thank Sheikh Fahad for buying him."
