FIELD: biotechnology.
SUBSTANCE: method consists in the fact that as a background for evaluation and sampling, a solution of sodium nitrate with concentration of 1.37 mol/l is used, in which the analysed test sample is immersed, after stirring, the number of floating caryopses is counted, at that, samples are referred to as resistant, in which not more than 25 % of caryopses have surfaced, to susceptible – those in which 50 % and more have surfaced, and the rest (from 25 to 50 %) – to relatively stable.
EFFECT: disclosed is a method of evaluating selection material for resistance to germination of grain in an ear.
