Luisetti Seeds’/ Plant and Food Research Wheat Breeding Programme Targets Barley Yellow Dwarf Virus
Original parent Viceroy (showing yellow leaves characteristic of BYDV infection).
A trial using a resistance wheat gene to control Barley Yellow Dwarf Virus is showing promising results.
Barley Yellow Dwarf Virus (BYDV) is an aphid transmitted virus prevalent in many cereals and is a major concern to arable farmers worldwide. Very little genetic resistance exists to BYDV so insecticides are...
Virus resistant wheats being developed by the Luisetti Seeds/Plant and Food Research wheat breeding programme
Barley yellow dwarf virus (BYDV) is a disease that can cause major yield losses in wheat. However, using a genetic tool called Marker Assisted Selection, staff working in the Luisetti Seeds/Plant and Food Research (PFR) wheat breeding programme have developed virus resistant breeding lines. The selected lines contain BYDV resistance (Bdv2) from crosses between Viceroy milling wheat and a Bdv2...
BYDV Resistance in Wheat
BYDV symptoms in a wheat crop
The first field trials of advanced wheat lines that feature resistance to barley yellow dwarf virus (BYDV) were sown in the 2015-16 season. Two series of lines were developed using marker assisted selection to track the BYDV resistance into the milling wheat Viceroy and biscuit wheat Empress. These breeding lines were assessed for their field performance relative...
