ASSESSMENT OF WATER RETENTION ABILITY OF LEAVES OF APPLE VARIETIES FOR DROUGHT-RESISTANT GENOTYPES IDENTIFICATION
The comprehensive assessment of indicators of water-holding capacity of the leaves of аpple cultivars of different ploidy and genetic origin is given in the article. The study has been carried out according to the standard programs and techniques of breeding and variety's study. The most drought-resistant genotypes of regional breeding - immune to scab triploid apple varieties of the Union, the Nocturne and diploid varieties of the Carmen and the Amulet are selected.
