The worldwide increased demand for biomass (food, feed, energy sources and fibers) demands new concepts to improve food security. Improved water and nutrient acquisition of plants is certainly one aspect of the value web and increased biomass production, and subsequently, a sustainable Bioeconomy. Phenotyping is the current bottleneck to accelerate plant breeding (Fiorani and Schurr, 2013), and new methods are needed to phenotype the root system in the field, which may lead to root systems with increased water and nutrient acquisition. ‘Shovelomics’ is a ‘low-tech’, high-throughput method (Trachsel et al., 2010) that allows the phenotyping of root crowns of single plants in large plant populations. This method was adapted to phenotype root systems of temperate and tropical cereals for architectural and anatomical root traits in the field. Based on the ‘shovelomics’ method, we developed novel high-throughput phenotyping platforms and pipelines for root crowns of field-grown, temperate cereals, including imaging stations for temperate and tropical grasses and a semi-automated imaging processing pipeline that links into the DIRT software (Bucksch et al., 2014) allowing fast phenotyping of root crowns. The methodology was used to measure variation of root traits within barley genotypes and specific groups in a field experiment. The groups were based on the origin of genotypes, including varieties from Norway, Germany, and Australia. A split-plot design with 7 repetitions was chosen to measure the existing variation within a field experiment including different levels of N-fertilization. Different root traits were extracted from the root images using the DIRT software and analyzed with the software GenStat 18.1. Novel root phenotyping platforms and pipelines have been established to measure the root crowns of temperate cereals in the field. This ‘low cost’ and high-throughput method is suited to measure root traits of temperate cereals, in the field supporting pre-breeding and breeding efforts. Those developments are the first steps towards an automation of field root phenotyping in the future, and are currently transferred to storage root crops. |
