“…del Blanco et al 2003;, other cultivars with relatively high FHB resistance come from this region, e.g. Chinese cultivars Ning 7840, Ning 894037 (Shen et al 2003a;Zhou et al 2003), Wangshuibai Jia et al 2005;Mardi et al 2005;Lin et al 2004Lin et al , 2006Ma et al 2006), Wuhan, Japanese cultivars Nobeokabozu and Nyu Bai (Nyubai) or Korean cultivar Chokwang (Yang et al 2005). Sumai 3 is a highly FHB resistant Chinese spring wheat cultivar which was derived from a cross between Italian wheat Funo and Chinese landrace line Taiwan Xiaomai Wheat.…”

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.

“…SigniWcant variations in the eVect of the QTL were observed across various studies using diVerent Chinese cultivars or their derivatives (Buerstmayr et al 2002;Shen et al 2003;Bourdoncle and Ohm 2003;Somers et al 2003). This QTL explained up to 60 % phenotypic variation in a Chinese cultivar 'Ning7840' (Bai et al 1999;Zhou et al 2002), 41.6 % in 'Sumai3' (Anderson et al 2001), and from 6 to 37.3 % in 'Wangshuibai' (Zhou et al 2004;Yu et al 2008b;Ma et al 2006). All these cultivars demonstrated a stable and high level of type II resistance despite of variation in R 2 for Fhb1; thus, Fhb1 is a critical QTL responsible for FHB resistance in most Chinese sources.…”

Resumo -O objetivo deste trabalho foi validar 19 marcadores microssatélites para resistência do trigo à giberela, em uma população não estruturada. Foram utilizados marcadores moleculares descritos na literatura como flanqueando QTLs de resistência à giberela em trigo, nos cromossomos 3B, 5A e 6B. Foram avaliadas 96 linhagens e cultivares de trigo quanto à severidade da infecção por giberela, em dois anos de avaliação. As linhagens e as cultivares foram genotipadas com 19 marcadores microssatélites. Os dados obtidos foram analisados pelo teste de Tukey e pelas análises de correlação, regressão linear simples e regressão múltipla; também foi estimada a eficiência de seleção dos marcadores moleculares. A severidade da doença variou de 1,95 a 41,3%, na média dos dois anos. Foram validados os QTLs nos três cromossomos avaliados. Os marcadores Xgwm389, Xgwm533, Xbarc180, Xbarc24, Wmc397, Xbarc101 e Wmc398 foram associados significativamente à resistência do trigo à giberela, tendo sido identificados alelos de resistência e de suscetibilidade. Os marcadores Wmc397, Xbarc101 (cromossomo 6B) e Xbarc180 (cromossomo 5A) têm potencial para uso na seleção assistida por marcadores moleculares, para resistência do trigo à giberela.Termos para indexação: Fusarium graminearum, Triticum aestivum, seleção assistida por marcadores moleculares, SAM. Validation of molecular markers for wheat resistance to Fusarium head blight in Brazilian wheat genotypesAbstract -The objective of this work was to validate 19 microsatellite markers for wheat resistance to Fusarium head blight (FHB), in an unstructured population. Molecular markers described in the literature as flanking QTLs of FHB resistance in wheat on chromosomes 3B, 5A, and 6B were used. Ninety six wheat lines and cultivars were evaluated for severity of FHB infection in two evaluation years. The lines and cultivars were genotyped with 19 microsatellite markers. The obtained data were analyzed by Tukey's test, and by correlation, simple linear regression, and multiple regression analyses; the efficiency of selection with molecular markers was also estimated. Disease severity ranged from 1.95 to 41.3% in the mean of the two years. QTLs in the three evaluated chromosomes were validated. The markers Xgwm389, Xgwm533, Xbarc180, Xbarc24, Wmc397, Xbarc101, and Wmc398 were significantly associated with FHB resistance in wheat, and alleles for susceptibility and resistance were identified. The markers Wmc397, Xbarc101 (chromosome 6B), and Xbarc180 (chromosome 5A) have potential for use in marker-assisted selection for resistance to FHB in wheat.Index terms: Fusarium graminearum, Triticum aestivum, marker-assisted selection, MAS. IntroduçãoA giberela ou a fusariose é uma das principais doenças do trigo (Triticum aestivum L.). É causada, principalmente, pelo fungo Fusarium graminearum Schwabe e ocorre em regiões onde o clima é quente e úmido (Casa et al., 2004). Além de reduzir a produtividade do trigo, o fungo produz a micotoxina deoxinivalenol (DON), que é prejudicial tanto para a saúde ...
