Rootstock genetics & improvement: new improved rootstocks with durable resistance to root-knot nematodes and phylloxera

The project will evaluate selected rootstocks by collecting and analysing data for yield, vigour, fruit and wine quality from four existing rootstock field trials. Markers linked to root-knot nematode and phylloxera resistance loci in V. cinerea that were successfully identified earlier, will be complemented by assessing additional resistant Vitis species using next generation mapping to identify markers linked to new resistance loci. Elite breeding lines containing multiple resistance genes will be produced for developing rootstock genotypes with durable pest resistance. Lastly, in vitro root-knot nematode and phylloxera screens will be developed to identify germplasm material that maintains pest resistance at moderate to high temperatures.
