Sažetak
Breeding winter wheat for resistance to Fusarium head blight cause predominantly by Fusarium graminearum Schw. is the most effective means to control this disease. The aim is to develop our own material with as high as possible level of resistance and yielding capacity. Resistance degree was tested in the field, in four replication, following a randomized block design at location Botinec under conditions of artificial infection during 2008 and 2009. Grain yield was evaluated under natural infection. In both years, 34 genotypes were tested for resistance to Fusarium head blight and yielding capacity, three of wich were standards for resistance: Roazon, Poncheau and D (48x42x6)2, and Sana, a standard for yielding capacity. In both years 12 identical genotypes were tested and 18 genotypes were tested in one year only. Of all genotypes in both years of testing, the highest levels of resistance to fusarium head blight were achived by the genotype Bc Lira (9, 16%) and the lines Bc 1 and Bc 7 (12, 23% and 14, 38% respectively) based on a visual rating index (VRI%). Average resistance level was <x>= 26.65%. Likewise, the mentioned genotypes achieved high grain yields, Bc 7 most of all (9622, 9 kg/ha), then Bc Lira and Bc 1 (8845, 9 kg/ha and 8404, 2 kg/ha respectively). Average grain yield was <x>=8225, 9 kg/ha, and the one achieved by Sana was 8681, 3 kg/ha. In additional to high yield, Bc Lira expressed the highest resistance level to Fusarium head blight. Bc Lira was registered bc the Croatin Committee for Variety Registration in 2009 as a new winter wheat variety. Applicaton of artifical ear infection with Fusarium graminearum Schw. has been proved very successful in our winter
