      Nitrogen (N) is the quantitatively most important nutrient in cropping systems. The use of nitrate as a mineral fertilizer is highly energy-intensive and causes greenhouse gas emission and groundwater pollution. Therefore, the need to reduce N-fertilizer input is pressing. In order to compensate that reduction, new crop genotypes must be sought with improved nitrogen use efficiency (NUE). While ...

      Abstract : "Rapeseed (Brassica napus L.) is an oil-containing crop of great economic value but with considerable nitrogen requirement. Breeding root systems that efficiently absorb nitrogen from the soil could be a driver to ensure genetic gains for more sustainable rapeseed production. The aim of this study is to identify genomic regions that regulate root morphology in response to nitrate availability. ...

    • Root Morphological Traits of Seedlings Are Predictors of Seed Yield and Quality in Winter Oilseed Rape Hybrid CultivarsPeer reviewedOpen access

      Article scientifique
      The root system is responsible for soil resources acquisition. Hence, optimizing crop root characteristics has considerable implications for agricultural production. This study evaluated a panel of twenty-eight European modern cultivars of oilseed rape (Brassica napus L.) cultivated in laboratory and field environments. Root morphology was screened using a high-throughput hydroponic growth system ...
