Sažetak
Within the winter wheat breeding program at the Bc Institute, besides yield and quality, great emphasis is given to improvement of resistance to important wheat diseases, primarily head scab (FHB) caused by Fusarium graminearum Schw. Test for resistance to FHB is mandatory for all new breeding lines, potential candidates for release. In 2012, at location Botinec, 25 winter wheat genotypes were tested for resistance to FHB under conditions of natural and, two methods of artificial infection (spray method and infection using the infected corn stalks). The severity of disease was rated visually as % of infected wheat head and as % of FHB damaged kernels. The highest average disease intensity was rated as % of FHB damaged kernels after spray method of infection (16.85%), while the lowest disease intensity was rated using the same rate under conditions of natural infection (0.44%). The highest correlation among the disease ratings was observed between the visual rate after spray method of infection and the same rate after infection using the corn stalk (r=0.70**). The lowest correlation was observed between the visual rate and % of FHB damaged kernels under conditions of natural infection. Among the studied genotypes significant differences in resistance to FHB were observed under all conditions of infection using both disease ratings. Lines 7976/09 and Bc 7945/09 were selected for release and Bc 6119/09 as the resistance donor for future breeding purposes.
