Norin 10 wheat

Norin 10 is a semi-dwarf wheat variety that has had a significant impact on global agriculture. It was developed in Japan during the mid-20th century and has since been used in breeding programs worldwide to increase wheat yields and improve disease resistance.

History

Norin 10 was developed by the Norin Agricultural Research Station in Japan in the 1930s and 1940s. The variety was created through a series of crossbreeding experiments involving several different wheat varieties. The goal was to create a wheat variety that was shorter and more resistant to lodging, a common problem in wheat cultivation where the stems of the plants fall over, making harvest difficult and reducing yields.

Characteristics

Norin 10 is a semi-dwarf variety, meaning it is shorter than traditional wheat varieties. This trait makes it more resistant to lodging and allows it to allocate more energy to grain production, increasing yields. Norin 10 also has improved disease resistance, particularly to rust, a common wheat disease.

Impact

The development of Norin 10 had a significant impact on global agriculture. The variety was used in the breeding programs that led to the development of the high-yielding wheat varieties used in the Green Revolution, a period of rapid agricultural advancement in the mid-20th century. These varieties have since been used to increase wheat yields worldwide, contributing to global food security.
