Seed storage proteins (SSP) in oilseed rape consist of 12S globulins (cruciferins) and 2S albumins (napins) that stand for around 70% of total seed proteins. Since napins contain more sulfur residues than cruciferins, they display a higher value for food or feed usages. Recent results demonstrated the potentialities of genetics to improve the 12S/2S ratio. However, the current methods to assess the SSP balance are still time consuming and difficult to handle, thus preventing the phenotyping of large sets of accessions. Plant material 100 accessions of winter oilseed rape : Conclusion: Encouraging results for 2S quantification with NIRS. The current calibrations can be used to roughly sort out the accessions upon 12S/2S content but need further improvements (e.g., wider calibration sets).
