Crosses between a set of deletion lines for chromosome 7D in Chinese Spring (CS) background and the CS-Hordeum chilense substitution line CS(7D)7Hch were used for the physical mapping of the genes(s) for lutein esterification on chromosome 7D. Genotyping by DArTSeq and using genomic tools allowed the identification of candidate genes with acyltransferase or GDSL esterase/lipase activity that are worthy for further investigation.

CP18412Life cycle inventories for the Australian grains sector
Production of grains and oilseeds is associated with considerable environmental impacts such as GHG emissions and eutrophication. This research developed life cycle inventories that were used to estimate the climate change, land-use, ecotoxicity, eutrophication and abiotic depletion (fossil fuel) impacts for crop production in 14 regions across Australia. These inventories will be an asset to practitioners and researchers aiming to estimate the impacts of products that use Australian crops as an input.
CP19052Evaluation by grafting technique of changes in the contribution of root-to-shoot development and biomass production in soybean (Glycine max) cultivars released from 1929 to 2006 in China
We adopted a grafting technique using cultivars released from 1929–2006 in China as the rootstock and the cultivar Zigongdongdou as the common scion. We found that the aboveground traits declined with year of release of stock cultivar, while the measured root traits did not change significantly with year of release. This study established a method to study the intact root system and facilitates improvement of soybean root system.

CP19016Improvement of some growth and yield parameters of faba bean (Vicia faba) by inoculation with Rhizobium laguerreae and arbuscular mycorrhizal fungi
Nitrogen and phosphorus are scarce in the soil, and the adequate supply of these nutrients depends on the use of chemical fertilisers, which are harmful to the environment and health. Beneficial soil microorganisms (bacteria and fungi) in symbiosis with plants can supply these nutrients to the plants and improve their growth and yield, reducing the chemical fertiliser inputs. In this study, single inoculation and co-inoculation with Rhizobium laguerreae and arbuscular mycorrhizal fungi improved growth and yield of faba bean.
CP19079Genetic characterisation and agronomic and nutritional value of bitter vetch (Vicia ervilia), an under-utilised species suitable for low-input farming systems
Intensive conventional agriculture has diminished the local biodiversity and soil quality, and (re)introduction of neglected grain legumes can reduce this environmental impact. We demonstrated that the legume species bitter vetch is worth consideration as crop for seed production under no-input farming systems, especially in marginal soils of Southern Europe with climate conditions similar to those of Central Italy.
CP18318Adaptability of cotton (Gossypium hirsutum) genotypes analysed using a Bayesian AMMI model
Cotton is a crop of great industrial importance. However, cotton cultivars have different productivities and fibre qualities when submitted to different environments. In this work, we use modern statistical techniques to identify cotton cultivars that have stable behaviour for these characteristics throughout Brazilian environments
CP19115Proteomic analysis of axillary buds of sugarcane at different cutting stages: evidence for alterations in axillary bud gene expression
Productivity of sugarcane crops varies at each cutting stage, and knowledge of proteins involved in the regrowth of sugarcane within the cutting process is important for the development of greater longevity cultivars. The present study revealed a reduction in the number of proteins at the fifth cutting stage. The reduction in the number of proteins may be related to the reduction in agricultural productivity, sprouting and tillering at advanced stages of the sugarcane crop.
CP18482Evaluating the shifts in rainfall and pasture-growth variabilities across the pastoral zone of Australia during 1910–2010
Shifts in rainfall and pasture-growth variabilities between 1910–1960 and 1961–2010 across the pastoral agricultural zone in Australia were investigated. In most pastoral regions where the rainfall variability increased in at least 66% of the area, the pasture growth variability increased proportionally, with regions in Northern Territory being the most affected. Identification of the most vulnerable pastoral agricultural regions will help to facilitate transitional changes and enable land managers and grazers to implement changes that reduce the impacts of high interannual rainfall variability.
