Norin 10 dwarf wheat

A Japanese semi-dwarf wheat whose short, stiff stalks could carry heavy heads without falling over.

Bred by Gonjiro Inazuka and released in 1935, Norin 10 carried the Rht dwarfing genes. Brought to the US after 1945, it gave Norman Borlaug the trait he needed to let fertilised wheat yield more grain instead of lodging.
