Donald Forsha Jones

Born 16 Apr 1890; died 19 Jun 1963 at age 73.American geneticist and agronomist whose hybridization methods for corn (maize) enabled an agricultural revolution. Prior methods of single-cross hybridization had disappointing results. In 1917, he invented the double-cross method of hybrid seed production, which solved a problem in producing useful strains that were uniform, true-breeding, while still vigorous and able to give greater yield. Earlier researchers obtained "pure lines" from self-pollination to eliminate the variable results of open-pollinated seeds, then investigated single crosses made between two such pure lines. For double-cross hybrids, Jones used two single-cross strains. By 1959, more than 95% of U.S. corn crops used hybrid seeds, producing twice the yield of 1929.«
