Fourdrinier and Too Many Sweets each won a division of the split Marlboro Nursery Stakes yesterday as Bowie opened a 36-day meeting.

Fourdrinier and Too Many Sweets quez and trained by Frank Whitely Jr., stalked the pace of Advance Reason in the first half of the Nursery, then drew away with with authority in 1:25 1/5 for the seven furlongs. Advance Reason held on well to be second, 4 1/2 lenghts behind the winner and six lenghts ahead of Win Nona.

Fourdriner is owned by Peter M. Brant of Greenwich, Conn., who said that his 2-year-old filly, which cost $52,000 in the Saratoga Sales, would next go in the Matron Stakes in New York.

Jockey Vasquez said of the daughter of Cyanne. "She has to be urged at all times to do her best. She is lightly raced and appears to want to go longer, too."

Bill Nemeti, rider of the second-place finisher, said. "The winner just galloped by me at the three-sixteenths pope."

Too Many Sweets, given another superb ride by veteran Bill Passmore, held on when challenged in the stretch to win the second half of the Nursery by three-quarters of a length over favored Mongo Queen. One is Enough was third, a nose farther back.

Jockey Wayne Rice astride Mongo Queen though for a moment he had enough reason to claim a foul against the winner after being crowded at the far turn. But he reconsidered after a brief talk with Coley Blind, the clerk of scales, and walked away saying, "She was in tight but it was because she could not be trained hard for this race that she got beat today."

Too Many Sweets ran the seven furlongs in a mediocre 1:26 3/5, some seven lengths slower than Fourdrinier's final time. Trainer Woody Stephens, who was saddling his 11th stakes winner of 1978, said. "This filly has been honest and I've asked her to do a lot. I don't think she'll go in the Matron. I'll look for something else for her."

The crowd of 8,413 pushed $974,400 through the mutuel windows, a rise in both categories. Last year the attendance at the opening of the fall meeting was 8,176 and the betting was $918,320.
