Moscow, 29 Dec – AIF-Moscow.

Scientists from Russia created a number of hybrids of wheat and wild wheat grass, which is very resistant to premature germination, according to a paper published in the journal PLoS One.

In addition, geneticists were able to find in their DNA a gene by nuclear transfer into the genome of wheat can greatly increase its yield.

“These data can be used for gene transfer by conventional methods of breeding in wheat, that is to create normal varieties of wheat resistant to pre-harvest sprouting using the genetic potential of wild relatives”, – quotes the press service of the Russian science Foundation the words of the head of the Center for molecular biotechnology, Russian state agrarian University-MTAA them. Timiryazeva Gennady Charles.

The secrets of great harvest. What determines the quantity and quality of wheat?

In addition to insects and rodents, the crop of cereals affected by rains and fogs. Due to contact with water and mist some ripe grain starts to germinate inside of the ear. Charles and his colleagues managed to make a step towards solution of this problem.

Scientists were able to identify genes associated with a given property. During the experiment it became clear that the device of the gene Vp-1, responsible for the growth of cereal germ in the last stages of its development, depends on the probability of seed germination. The most rare form of this gene – ThVp-1d – able to keep a hybrid of wheat and couch grass from sprouting. This gene is present in approximately 15% of cereals.

According to scientists, it can be moved in the DNA of the varietal wheat to enhance resistance of grasses to adverse weather.

In addition, the study of hybrids can further help bring varieties of cereals, possessing the best properties of wheat and Wheatgrass, and free of defects.
