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.
F1 hybrid (also known as filial 1 hybrid) is the first filial generation of offspring of distinctly different parental types. [1] F1 hybrids are used in genetics, and in selective breeding, where the term F1 crossbreed may be used. The term is sometimes written with a subscript, as F 1 hybrid. [2] [3] Subsequent generations are called F 2, F 3 ...
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]
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 ...
The adjacent western provinces and northern US states are similar, so the use of corn as cattle feed has been limited at these northern latitudes. As a result, few cattle are raised on corn as a feed. The majority are raised on grass and finished on cold-tolerant grains such as barley. [61] This has become a marketing feature of the beef. [9]
The oldest type of sweet corn contains more sugar and less starch than field corn intended for livestock. Tends to be heartier in respect to planting depth, germination and growth than other types. Tends to be heartier in respect to planting depth, germination and growth than other types.
