Successful breeding of wheat tolerates salinity

New Australian scientists successfully tested hard-boiled wheat to withstand salinity, increasing grain yield to 25% in saline soils.

Using conventional breeding techniques, scientists at the University of Adelaide and the Commonwealth of Science and the Industrial Research Organization (CSIRO) have released a new wheat variety containing genes that remove sodium salt from rice. Triticum monococcum noodles (close relatives with modern wheat) allow water to move from roots to leaves to grow plants.

Wheat is one of the most widely grown grains in the world, but in saline soils, it is vulnerable to salt accumulation in leaves, which can hinder growth and reduce yields, threatening security. Food.

The study uncovered crops and wheat varieties that can grow on saline soils, to develop grain crops. Moreover, this conventional breeding technique will give seeds much cheaper price for genetically modified seeds. Scientists are planning to sell new wheat seeds within the next 5 years.

It is known that saline soils affect more than 20% of the world's agricultural land, making it difficult for agricultural irrigation systems, especially in high saline areas. In the United States, one of the world's largest wheat exporters, each year the damage from salinity is up to $ 12 billion.

However, there are also concerns that the dissemination of this wheat variety will reduce interest in saline soil improvement by farmers.
