High throughput field phenotyping in cereals
Acceleration of breeding advance is needed urgently given the challenges expected from climate and social changes. Nevertheless, constraints in phenotyping capability limit our ability to dissect the genetics of quantitative traits, especially those related to harvestable yield and stress tolerance. In particular, phenotyping under real (i.e. field) environmental conditions remains the bottleneck for future breeding advances (Araus et al. 2008, 2012; Cairns et al. 2012; Cabrera-Bosquet et al. 2012).
In that sense, development of field-based high throughput phenotyping platforms (HTPPs) at an affordable cost is urgently needed to help crop breeding in developing countries (Cairns 2013). The HTPP will also allow the rapid characterisation of field variability so as to increase the genetic signal to noise ratio to detect real differences between genotypes (Masuka et al. 2012).
HTPPs are based on high capacity for data recording/scoring and processing, and non-destructive, non-invasive and remote sensing phenotyping methods (Cabrera-Bosquet et al. 2011; White et al. 2012) based mostly in the information provided by visible/near-infrared radiation reflected (Weber et al. 2012) and far-infrared radiation emitted (Zia et al. 2013) by the crop. Examples of affordable HTPPs for field evaluationare presented and discussed.
In addition the analysis of the natural abundance of stable isotopes in plants (Yousfi et al. 2012), particularly of carbon (Araus et al. 2013), may complement direct phenotyping under field conditions, even more if these analyses may be assessed in a costless manner (Cabrera-Bosquet et al. 2011).
