Sažetak
Breeding of Bc wheat cultivars for resistance to Fusarium head blight is aimed at reducing the negative effects of the disease on grain yield quality and developing our own material with the highest resistance and yield ability. Wheat lines were tested for resistance to Fusarium head blight and grain yield in field trials at Botinec in 2004. and 2005. under artificial and natural infection. In 2004., the highest level of resistance and grain yield was in the line Bc 310/01 (14, 7 ; 8.108kg/ha) and line Bc 5073/00 (14, 7 ; 8.052kg/ha). In 2005., the highest level of resistance was in the line Bc 9362/99 (7, 6 ; 8.972kg/ha). A high level of resistance also was expressed in lines Bc 5325/02 (10, 3 ; 8.511kg/ha) and Bc 18/91 (6, 1 ; 8.124kg/ha). Three lines had good levels of resistance, Poncheau (5, 0) and (D48x42x6)2 (10, 3), Roazon expressed a lover level of resistance (20, 7). Breeding for resistance to Fusarium head blight has proven to be successful because of a very effective method of artificial inoculation. Good levels of resistance also have been achieved because a good selection of sources of resistance, such as Beauchamp, SO– 1065, 434K – 4CM, Mold 1304-83, FD – 91147, and the local source Bc 87/87.
