FIELD: agriculture.
SUBSTANCE: invention may be used for selecting immune and highly resistant to cocco mycosis sweet cherry and cherry varieties and root stocks for the above crops. During active leaves growing, they are subject to diagnostic analysing by producing UHF extract of phenol compounds. The produced extract is diluted with the distilled water at a ratio 1:4-1:5 and a sample is supplied to amperometric analyser. The type resistance to infection is judged based on the availability of detector signal at 0.4 V potential on glassy-carbon electrode.
EFFECT: reduced time for infection-resistant types selection and essential improvement of results reliability.
