| Abstract: | A review of Septoria diseases of wheat is given with particular emphasis on the resistance of this host to Septoria nodorum Berk. Following a general historical outline, the effects of glume blotch on the wheat plant are described, including symptoms and physiological changes. Brief reference is made to epidemiological studies, and then resistance breeding and genetic studies are discussed. The role of antifungal compounds in resistance is dealt with in more detail, and with reference to the author's own research results. It is concluded that no single mechanism of resistance of wheat to S. nodorum emerges and that the resistance factors appear to be varying quantitatively rather than qualitatively. |
