High throughput precision phenotyping (HTPP) in durum wheat: physiological basis and tools for selection - Goetz Program Report

May 25, 2016

By Omar Vergara Diaz, PhD candidate; Dr. Shawn Carlisle Kefauver, post-doctoral researcher; Dr. Jose Luis Araus, professor. Department of Plant Biology, Faculty of Biology, University of Barcelona, Spain.

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.

Studying Mars mineralogy with an ASD FieldSpec - on Earth

Davies, D. Tedesco, I. Daniel and C. Quantin (see references).

This project was funded by a NWO (Netherlands Science Organization) VENI fellowship attributed to Dr. Jessica Flahaut. Dr. Janice Bishop is grateful for support from the NASA Astrobiology Institute.

The identification and characterization of hydrated minerals, within ancient aqueous environments on Mars, are a high priority for determining the past habitability of the red planet. Few studies, however, have focused on characterizing entire mineral assemblages as this is often difficult to determine from remote sensing data, even though this could aide our understanding of past environments. This is especially true for the sulfate-rich deposits, which are thought to mark a transition to more acidic conditions at the Martian surface about 3.5 Ga. This transition would coincide with a period of global climate change. As a result, quantitative constraints on Martian habitability during the ‘Mars global change’ era remain poor.

Introducing the 2016 Goetz Program participants

February 25, 2016

In recognition of the long-standing contribution of ASD co-founder to the field of remote sensing, the annual Goetz Instrument Support Program was established to further encourage a creative research environment within the Remote Sensing and Field Spectroscopy world-wide community. The intent is to provide a simple mechanism for supporting small research efforts which can quickly establish concept viability, or rule out further consideration, by providing temporary use of a field spectroradiometer, which might otherwise be difficult to obtain.
