Exploiting Genetic Variability of Root Morphology as a Lever to Improve Nitrogen Use Efficiency in Oilseed Rape
29 juillet 2018, HE CondorcetCARAHLivre/Ouvrage ou monographieNitrogen (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 ... -
In-Field Observation of Root Growth and Nitrogen Uptake Efficency of Winter Oilseed Rape
10 janvier 2020, HE CondorcetCARAHArticle scientifiqueField trials were conducted with two nitrogen applications (0 or 240 kg N ha−1) and three modern cultivars of winter oilseed rape (Brassica napus L.) previously selected from a root morphology screen at a young developmental stage. The purpose is to examine the relationship between root morphology and Nitrogen Uptake Efficiency (NUpE) and to test the predictiveness of some canopy optical indices for ... -
Root Morphological Traits of Seedlings Are Predictors of Seed Yield and Quality in Winter Oilseed Rape Hybrid Cultivars
15 octobre 2020, HE CondorcetCARAHArticle scientifiqueThe 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 ...
