William Joseph Sando, 98, a retired Agriculture Department agronomist who was an American pioneer in wheat genetics, died Nov. 28 of pneumonia at Providence Hospital. He had lived in Washington since 1900.

Mr. Sando worked for 50 years developing disease-resistant strains of wheat, crossing wheat genes with those of wild grasses. The germ plasma he developed is still used by grain researchers in this country and abroad.

His early work on wheat genetics, particularly in the 1930s and 1940s, brought him national attention, including a citation from then-Agriculture Secretary Henry Wallace. A drawing of Mr. Sando's hands, shown pollinating wheat, once appeared on the cover of Nation's Business magazine to illustrate a story about breakthroughs in agriculture research.

Mr. Sando joined the Agriculture Department in 1909 as a messenger. He later assisted a plant geneticist, William Jasper Spillman, then became a full-time research assistant with the department in 1916. Five years later, he joined the department's Bureau of Plant Industry and worked on wheat strains there and later at the department's Beltsville research station. He formally retired from the department in the early 1960s, but continued as a reseach collaborator for a decade.

Mr. Sando was a native of Bernville, Pa., and a graduate of Washington's old Business High School. He received bachelor's and master's degrees in agriculture at the University of Maryland. He served with the Army in France during World War I.

Survivors include his wife, Emma L. Sando; his son, William Jasper Sando of Alexandria; two grandsons; and five great-grandchildren.
