“…Gosman et al (2007) investigated FHB resistance in 50 cultivars from the U.K. National List of winter wheat cultivars approved for sale and they found out that only three cultivars (Soissons /rht-B1b, rht-D1a/, Spark /rht-D1a/ and Vector) exhibited a higher level of FHB resistance than the FHB-susceptible cultivar Wizard. A moderate level of resistance to FHB was also found in the currently grown Czech cultivars Simila and Alana , Sakura (Horčička et al 2007) (Figure 1) and Bakfis, which possesses above all Type V FHB resistance (Laml & Pánek 2008). These cultivars are promising sources of FHB resistance with adaptation to European conditions.…”

The aim of this review is to summarize recent information on Fusarium head blight (FHB) in small grain cereals, especially in wheat and barley. Basic information on FHB epidemiology, types of resistance and plant resistance mechanisms is included. Standard methods for the evaluation of the individual types of FHB resistance and the extent of infection are briefly described. Special attention is paid to the sources of FHB resistance of different origin and possibility of their exploitation in cereal breeding. Unfortunately, a high level of FHB resistance was detected in non-adapted germplasm or distant relatives, which is a serious impediment to breeding progress in this field. The present state of breeding for FHB resistance in wheat, barley, rye, triticale and oats was analyzed. It was shown that large-scale QTL detections provide new opportunities for increasing the resistance; however, multi-step phenotypic selection still remains to be the most effective tool. Pedigree analyses indicated that the latest progress reached in this field was obtained through the cumulation of resistance genes coming from heterogeneous sources with different response to FHB.

“…Another 9 varieties (Federer, Baletka, Samanta, Sakura Brilliant, Dromos, Košútka, Sultan and Hedvika) were included in the same "a" group, however, as seen in Table 2, some of them expressed high instability over years (5 lastly mentioned varieties), and therefore only six varieties (Bakfis, Arina, Federer, Baletka, Samanta and Sakura), significantly differing from the MS and S groups, could be considered as moderately resistant to accumulation of DON. The information about the moderate resistance of varieties Bakfis and Federer, together with the description of other important properties of these varieties, was lately provided by Pánek (2008, 2010) and about high resistance of Sakura by Horčička et al (2007) and Šíp et al (2010).…”

Abstract:Resistance of 31 winter wheat varieties (bred in 6 European countries) to Fusarium head blight (FHB) was evaluated in field trials lasting for three years (2007, 2008, 2009) after artificial inoculation with Fusarium culmorum. The data on deoxynivalenol (DON) content were supplemented by symptom scores and determination of % of Fusarium damaged grains and % reductions of thousand-grain weight and grain weight per spike due to infection. These varieties and also 120 advanced breeding lines from the Úhřetice Breeding Station, SELGEN company were examined for the presence of gibberellic acid (GA) insensitive semi-dwarfing genes to evaluate their effect on FHB. The conditions of experimental years highly influenced the performance of all characters. The highest production of DON occurred in 2008 at a high temperature and high moisture content during the infection period. In all years the moderate resistance to accumulation of DON (at the level of Swiss variety Arina) was detected in the Czech varieties Bakfis, Federer, Baletka, Samanta and Sakura. Among these varieties, Federer showed a low accumulation of DON at a relatively higher symptom expression and greater reduction of grain weight per spike, but the other four varieties and the reference variety Arina expressed resistance in all the examined traits. The varieties Pitbull, Cubus, Kodex and Bagou were found to be highly susceptible to FHB. The presence of the dwarfing allele rht-D1b resulted in a significantly higher mean symptom score and also in a higher affection of the other traits. Nonetheless, the analysis of frequency distributions in symptom scores showed the presence of resistant lines also among the GA insensitive lines, but with a lower frequency than in the group of GA sensitive genotypes. A relatively greater effect on manifestation of the disease had plant height, and therefore it is suggested that the adverse impact of rht-D1b on FHB resistance could be to a high degree excluded by opting for taller rht-D1b genotypes.
