Former Rep. J. Floyd Breeding (D-Kan.), who was elected to Congress in 1956 and served through 1962, died Monday in Dodge City, Kan., following surgery. He was 76.

He had run for office as an opponent of the Eisenhower administration's farm program. He was defeated in his race for a fourth term by then incumbent Rep. Robert J. Dole, who later became a senator and vice presidential candidate.

Born near Robinson, Kan., Mr. Breeding moved to Rolla in 1928. He and his wife, Sue, settle on a farm there and stuck to their land during the Depression and the drought and dust storms that swept western Kansas in the 1930s and 1950s. Mr. Breeding was a stockman as well as a farmer. They had two sons who also became farmers.

He served in the state House of Representatives during 1947-49, and was minority leader in the 1949 session.

In 1951, he became president of the Western Kansas Development Association and a spokesman for the National Association of Wheat Growers.

After his election defeat in 1962, Mr. Breeding held a position with the U.S. Agriculture Department. He left his job in 1965 to run unsuccessfully for a seat in the U.S. Senate.
