Martina Navratilova, seeking her fifth consecutive women's singles title, and French Open champion Ivan Lendl yesterday were named the top seeds for the Wimbledon tennis championships, which begin Monday.

American John McEnroe, a three-time Wimbledon winner, is on a sabbatical from tennis and is skipping this year's tournament. Also missing from the men's field are Frenchmen Yannick Noah, who has a severely burned ankle, and Thierry Tulasne.

Mikael Pernfors of Sweden, a surprising French Open finalist, is seeded 13th in the men's singles, and American Tim Mayotte, who won the Stella Artois crown at Queens Club on Sunday, is seeded 10th.

American Jimmy Connors, who had to retire with an injury in the second set of the Stella Artois championship match, is seeded third, behind Lendl and Sweden's Mats Wilander. West Germany's Boris Becker, the defending champion at Wimbledon, is the No. 4 seed.

Chris Evert Lloyd, who won a record seventh French Open women's singles title, is seeded second behind Navratilova.

West German teen-ager Steffi Graf was seeded third, but she withdrew from the tournament because she is suffering from a virus. Graf had the illness during the French Open, but managed to reach the quarterfinals before losing to second-seeded Hana Mandlikova of Czechoslovakia.

Seeded behind Graf at Wimbledon were Mandlikova, West Germany's Claudia Kohde-Kilsch and Americans Pam Shriver and Kathy Rinaldi. . . .

Navratilova, the top seed, and Mandlikova, the No. 2 seed, started their Wimbledon warm-up with straight-set victories in the first round of the $200,000 Eastbourne (England) grass court championships.

Navratilova eliminated Catherine Tanvier of France, 6-1, 6-3, and Mandlikova ousted Australian Janine Thompson, 6-1, 6-2.

In other matches, Helena Sukova of Czechoslovakia beat American Camille Benjamin, 6-3, 7-5; American Barbara Potter stopped Britain's Sally Reeves, 2-6, 6-7 (7-3), 6-2, and Britain's Jo Durie pleased the home crowd with a 6-2, 6-2 triumph over Adriana Villagran of Argentina.
