Abstract

Anther extrusion has been widely discussed as a factor influencing fusarium head blight (FHB) resistance in wheat. This is despite a paucity of quantitative information on its importance, between cultivars, in contrast to that for heading date and plant height. We describe a method applicable to a plant breeding
situation at 10 days postanthesis, for assessing the distinct characteristics of anther retention (anthers held within the spikelet) and trapped anthers (partially
extruded and trapped between the lemma and palea of the wheat spikelet). FHB resistance was tested in field experiments in 2004 and 2005. In these experiments designed to resemble applications to a plant breeding selection scheme anther retention was significantly correlated with FHB in 2004 (r = 0.26; P < 0.05) and 2005 (r = 0.26; P < 0.05). A higher proportion of anthers retained relating, albeit weakly, with increased FHB susceptibility in European wheat.
