Hughes said the Begg stable had not had a lot of experience with the progeny of Blue Point and for that reason just took Riverina Lulu along slowly.
"A lot of them have been showing good ability which hasn't always translated into race day," Hughes said.
"But she went to the jump-outs on very heavy ground and just motored through it, so that meant today was the right time of the year to come to the races.
"To do that on debut against race experienced horses and cope with the day, it's suggestive of a really nice horse going forward."
Hughes, who has had a long association with the Begg stable, said 'the boss' was likely to let the dust settle on Saturday's win and plot a path to the spring.
"He might hold on to her now and give her a little blow and get ready for the spring," Hughes said.
"Timing wise we're pretty close to the spring, but there might be a nice race in the spring here if that's the way he wants to go.
"She's from a very fast colonial family and when you look at her, she's just a barrel on wheels.
"She's a speed horse and winning over 1000 metres is one thing, but whether she gets 1200 metres is another thing.
"I'm sure Grahame will just let the dust settle and plot a path."
