Hybrid corn was detasseled manually until the mid-1950s, when a cytoplasm was discovered that would cause one of the inbred lines to be male sterile while the hybridized seed corn it produced would regain male fertility. This gene allowed seed corn companies to greatly reduce their labor costs by producing seed corn without the need for manual ...
Hybrid seeds planted by the farmer produce similar plants, but the seeds of the next generation from those hybrids will not consistently have the desired characteristics because of genetic assortment. It is therefore rarely desirable to save the seeds from hybrid plants to start the next crop. [4]
The seed from two initial crosses are used to grow up parental hybrids for the production fields. The production fields yield seed in sufficient quantity to make the scheme practical. Until Jones invented the double-cross method, the yield from the parent lines (the inbreds) was insufficient to allow practical production of hybrid corn seed. [2]
1926 - Hi-Bred Corn Company is founded in Des Moines, Iowa, with $7,000 in capital. [7] 1931 - Roswell Garst agrees to produce/distribute seed. The following year Garst partners with Charles Thomas to form the Garst and Thomas Seed Corn Company. 1935 - "Pioneer" was added to the name of the company to distinguish it from other hybrid corn ...
As a result, DeKalb was the leader in U.S. hybrid seed corn sales from the mid-1930s until the mid-1970s (Crabb 1948. Roberts 1999). [2] In 1982 DeKalb formed a joint venture with Pfizer, called DeKalb-Pfizer Genetics, and in 1985 the name was changed to DeKalb Corporation. The seed business was spun off as DeKalb Genetics Corporation in 1988. [4]
Foundation corn is the parent seed from which hybrids are made. Established in 1937, in Williamsburg, Iowa by Roland Holden, Holden was the largest independent producer of foundation seed in America before being acquired by Monsanto Company in 1997. [1] [2] Monsanto was subsequently acquired by Bayer in 2018, and Holden is now part of Bayer ...
Roswell "Bob" Garst (June 13, 1898 – November 4, 1977) was an American farmer and seed company executive. He developed hybrid corn seed in 1930 that allowed greater crop yields than open-pollinated corn. He was perhaps most well known for hosting Nikita Khrushchev on his farm in Coon Rapids, Iowa, on September 23, 1959.
The hybrid offspring of the sickly pure breeds were vigorous and predictable. In short, an ideal economic maize resulted from a project motivated purely to advance science. [ 2 ] For his work on maize, Shull was awarded the Public Welfare Medal from the National Academy of Sciences in 1948. [ 3 ]
