Breeding oilseed rape with a low requirement for nitrogen fertiliser

Project Report No. 479 on the selection of oilseed rape varieties with a low requirement for fertiliser N and possible genetic selection to reduce pollution and costs associated with growing oilseed rape.

Year of Publication2011

The relatively small number of previous studies into oilseed rape nitrogen use efficiency, together with the increasing cost of nitrogen fertiliser and concern about greenhouse gas emissions and nitrate leaching, create a need for an improved understanding of the varietal traits associated with yield under low nitrogen conditions in oilseed rape. This project aimed to address this need using a series of field experiments to understand the physiological mechanisms and identify the traits which determine yield differences between varieties grown under low nitrogen supply. A further objective involved developing methods which plant breeders could use to rapidly select varieties with low nitrogen requirement.
