摘要：
A two-year estimation of Botrytis cinerea stem damage of 299 experimental F-1 hybrids grown in 2 rotations: winter-autumn and summer-autumn was carried out. The estimation was made in a period of mass fruitage. As a result it was shown, that the hybrids with determinate type of growth (sp) are damaged more strongly than indeterminate ones (sp +). An average disease severity in the first group was 2.8 against 2.3 in the second one using a scale 0-4. Number of strongly injured (2.5-4) planes in each group were 44.1 % and 30.7 % and number of moderate resistant (0-1.5 numbers) plants were 10 % and 8.5 % accordingly. The analysis of resistance of F-1 hybrids determined significant influence of parental lines on a degree of a damage of plant stems by B. cinerea.
