Explanation:

In 1935, the work of Japanese scientist Gonjiro Inazuka to cross a semi-dwarf Japanese wheat landrace with two American varieties resulted in an improved semi-dwarf variety, known as Norin 10. Unlike other varieties, which stood taller than 150 cm, the Rht1 and Rht2 genes present in Norin 10 reduced its height to 60–110 cm. In the late 1940s Orville Vogel at Washington State University used Norin 10 to help produce high-yielding, semi-dwarf winter wheat varieties.
