With the falling number test, so-called weather- or sprout-damaged wheat or rye, which adversely affects bread-making quality, could be detected at the grain silo intake within a few minutes. Sprouting , or pre-harvest germination , is caused by damp or rainy weather conditions during the final stage of maturation of the crop.
Production of some products is highly concentrated in a few countries, China, the leading producer of wheat and ramie in 2013, produces 95% of the world's ramie fiber but only 17% of the world's wheat. Products with more evenly distributed production see more frequent changes in the ranking of the top producers.
A map of worldwide wheat production in 2000 Wheat is one of the most widely produced primary crops in the world. The following international wheat production statistics come from the Food and Agriculture Organization figures from FAOSTAT database, older from International Grains Council figures from the report "Grain Market Report".
By fully sequencing all 827 varieties found in the Watkins Landrace (a.k.a. heritage) Collection, the researchers determined that modern wheat displayed only 40 percent of the diversity found in ...
The Watkins Landrace Wheat Collection is a unique resource due to the historical nature of being collected in the 1930’s before widespread globalisation of trade, and before intensive selective breeding in wheat to develop high-yielding elite varieties, which resulted in a significant loss of genetic diversity, including resilience traits.

A new variety might, for example, be higher yielding, more disease resistant or have a longer shelf life than the varieties from which it was bred. The practical use of crop diversity goes back to early agricultural methods of crop rotation and fallow fields, where planting and harvesting one type of crop on a plot of land one year, and ...
The International Maize and Wheat Improvement Center (known – even in English – by its Spanish acronym CIMMYT for Centro Internacional de Mejoramiento de Maíz y Trigo) is a non-profit research-for-development organization that develops improved varieties of wheat and maize with the aim of contributing to food security, and innovates agricultural practices to help boost production, prevent ...
Modern wheat varieties have been selected for short stems, the result of RHt dwarfing genes [14] that reduce the plant's sensitivity to gibberellic acid, a plant hormone that lengthens cells. RHt genes were introduced to modern wheat varieties in the 1960s by Norman Borlaug from Norin 10 cultivars of wheat grown in Japan .
