WASHINGTON (AP) _ Nancy Reagan cribbed a line from ''The Wizard of Oz'' on Tuesday to help honor six families who have shown civic leadership and strong family values.

''A heart is not judged by how much you love, but by how much you are loved by others,'' Mrs. Reagan said, lifting a line spoken by Wizard in the famed movie.

''May your families continue to flourish and enrich our nation for many more generations,'' the first lady said, presenting the Great American Family Awards in an East Room ceremony.

The recipients included a family with 17 children from Indiana and a single-parent family from North Carolina. The awards are sponsored by the American Family Society, a non-profit group dedicated to helping parents build strong families, and were chosen by a panel that included Art Linkletter, Mary Lou Retton, and Maj. Gen. Stuart E. Barstat, chief of chaplains for the U.S. Air Force.

The honorees included:

- Stanley and Brenda Hoisington, of Fort Campbell, Ky.; honored for their public service, support of various community projects and involvement with their eight children.

- Mildred Morris of Asheville, N.C., who has been a single parent to two of her own children and 10 foster children.

- Richard and Sue Stevens of Arlington, Texas, who have two adopted sons and been involved with a school for learning-disabled children.

- William and Anne Sweeney, of Subic Bay, Philippines, who have three children of their own and seven adopted children, and are involved in several humanitarian efforts in the Philippines.

- Bernard and Florence Veldman, of Mishawaka, Ind., who have five of their own children, six adopted and six foster children.

- Jason and Geraldine Weinner, of Orlando, Fla., whose family of eight has helped one son blinded by an eye disease enter college at age 15 and learn seven languages proficiently.
