METHOD FOR SELECTING HIGHLY PRODUCTIVE BUCKWHEAT GENOTYPES BY WATER USE EFFICIENCY Russian patent published in 2023 - IPC A01H1/04 

FIELD: biotechnology.

SUBSTANCE: invention relates to the field of biotechnology. The invention is a method for selecting highly productive buckwheat genotypes according to the efficiency of water use, which consists in calculating the ratio of the intensity of photosynthesis to the intensity of transpiration, including measuring the intensity of photosynthesis and the intensity of leaf transpiration, which is carried out from 8:00 to 10:00 pm local time using a portable gas analyzer brand GFS-3000 FL, the measuring chamber of which is attached to the leaf of the plant, while in the measuring chamber the lighting mode is set to 1000 mcmol/m²s, according to the invention, measurements are carried out on a leaf located on the first fruiting node of the main shoot of the plant in the phase "flowering + 20 days”, while varieties and breeding samples with a value of water use efficiency that is 20% higher than the average for the estimated sample are recognized as highly productive genotypes.

EFFECT: using this method, it is possible to select highly productive buckwheat genotypes already at the early stages of breeding.
