Oilseed rape (OSR) is a crop of high economic value grown mainly for its oil.Despite its high nitrogen (N) absorption capacity,OSR has a low N use efficiency.To propose N efficient cultivars,an extended knowledge of the genetic control of oil yield elaboration under N constraints is needed.The objectives of this work were to determine the QTLs of OSR associated with oil yield and to assess their stability under various N conditions.Two mapping populations,AM and DK,were tested in two locations (Md and LR) during two growing seasons (2010-2011 and 2011-2012),each time under two N levels:high (N2) and low (N1).Six yield-related traits,including grain yield,oil content and oil yield were evaluated.
