infection process

Catalogue: GRDC Final Reports
The aim of the project was to clone the scald resistance gene Rrs1 from barley and identify more resistant barley germplasm that is not used by barley breeders... Results show that Rrs1 resides at a genome region hosting a suite of 10-14 similar genes that are candidates for resistance genes against different scald pathotypes... The aim of the research is to generate molecular tools that allow the identification of scald infection objectively (no subjective scoring) and significantly earlier than the appearance of leaf symptoms...

Sowing a susceptible wheat variety on stubble of a previously infected susceptible variety (e.g. Gregory-on-Gregory) represents a much higher risk for developing high levels of yellow spot... The incidence and severity of yellow spot increases as moisture periods lengthen such that it takes repeated rain events to drive the disease from the lower to the upper canopy later in the season... Yellow spot is generally considered a significant disease in very wet seasons (e.g. 1998 and 2010) where yield losses of up to 30% have been recorded in susceptible wheat varieties...
