METHOD OF SELECTING GENOTYPES OF BUCKWHEAT AND SOYA, RESPONSIVE TO HIGH CONTENT OF CARBON DIOXIDE IN AIR Russian patent published in 2021 - IPC A01H1/04 

FIELD: biotechnology.

SUBSTANCE: invention relates to the field of biotechnology. Invention is a method of selecting genotypes of buckwheat and soya, responsive to high content of carbon dioxide in air, comprising measuring photosynthesis intensity of leaves, wherein measurement is carried out from 9:00 to 11:00 a.m. using a portable gas analyzer of LI-6400 XT or an analogue, measuring chamber of which is attached to a plant sheet, for measurement, leaves of the first fruit-bearing node are selected during the fruit-forming phase, according to the invention, in a measuring chamber of a portable gas analyzer, a normal concentration of carbon dioxide corresponding to an average annual value in the earth's atmosphere, and an increase in concentration of carbon dioxide by 4 times, are set, wherein the genitive types of buckwheat and soya are considered responsive, in which concentration of carbon dioxide is increased by 4 times, photosynthetic intensity increases by at least 2.3 times.

EFFECT: using this method, it is possible to estimate genotypes of buckwheat and soya by reaction of their plants to concentration of carbon dioxide in air with high accuracy and minimum time expenditures and to allocate among them the most responsive to the raised maintenance of carbonic gas in air.
