Like other small grain cereals, triticale (×Triticosecale Wittmack) is also affected by Fusarium head blight (FHB) which is a serious plant disease leading to yield losses and to a contamination of feed and food by harmful mycotoxins. Use of resistant varieties is the most effective way to manage FHB infections. More recently, commercial hybrid breeding in autogamous cereals has received increased interest. Therefore, we built a bridge between hybrid and resistance breeding and conducted a multi-environmental field trial using deliberate inoculation with Fusarium culmorum to: (i) evaluate different hybrid prediction approaches based on phenotypic and/or genomic data; (ii) compare the effect of cytoplasmic male sterility (CMS) inducing cytoplasm and normal (N) cytoplasm on FHB resistance. We evaluated 226 single cross hybrids, their paternal and maternal lines in both CMS- and N-cytoplasm. Our …
