Breeding oilseed rape with a low requirement for nitrogen fertiliser - LK0979

Description
Oilseed rape receives more nitrogen fertiliser than almost any other arable crop, but the amount of nitrogen removed in the seed is relatively small. The high fertiliser requirement represents a large growing cost and, because of the high energy input and by-products produced during its manufacture, it causes significant green house gas emissions to be associated with growing the crop. The nitrogen rich crop residues also cause a high risk of nitrate leaching. These factors reduce the viability of oilseed rape for biodiesel and food production. Because there is known genetic variability in the N requirement of oilseed rape which has not previously been tapped, prospects are good for breeding oilseed rape with a low N fertiliser requirement. It is estimated that the N fertiliser requirement of high yielding crops can be halved. Before commercial breeding can proceed, methods of rapidly screening for low N requirement and its underlying traits must be developed, and suitable sources of genetic variation must be identified.
Objective
To improve the viability of UK oilseed rape for biodiesel and food production by reducing green house gas emissions, nitrate leaching and financial costs associated with growing the crop.
