A FieldSpec 4 equipment was kindly provided by ASD Alexander Goetz Instrument Program and it was intended for supporting our studies of the ecophysiological and agronomic characterisation of durum wheat in field conditions. The general objective of our research is to develop high-throughput phenotyping techniques and to deepen the physiological and molecular basis involved in the adaptive response of durum wheat across a wide range of environmental conditions.
For this aim, a panel of 24 semi-dwarf genotypes (post- Green Revolution) of durum wheat marketed in Spain over the past four decades are used as a retrospective study. The panel was cultivated under conditions of rainfed and supplemental irrigation at two field stations in Colmenar de Oreja (Madrid) belonging to the National Institute for Agricultural and Food Research and Technology (INIA) of Spain, in Zamadueñas (Valladolid) belonging to the Castilla y León Institute of Technology and Agriculture (ITACyL) and in rainfed conditions in Coria del Río (Seville) also belonging to INIA. Thus a wide range of latitudes was covered from northern to southern Spain.
