CP23078Identification of superior genotypes for leaf architecture traits in Sorghum bicolor through GGE biplot analysis

Runfeng Wang 0000-0002-8212-3674, Yingxing Zhao, Hailian Wang 0000-0002-5536-662X, Erying Chen, Feifei Li, Shaoming Huang 0000-0002-9829-0303, Ling Qin, Yanbing Yang, Yan’an Guan, Bin Liu and Huawen Zhang
 

Grain sorghum is a food source for people in semi-arid regions; however, its productivity is compromised by its inefficient leaf architecture. Aiming to improve sorghum productivity, the research focused on evaluation of leaf architectural traits and identification of ideotypes with outstanding leaf architecture. Through multi-environment trials, an ideal genotype was selected for best leaf architecture performance, which will be useful as the parental line to optimise sorghum leaf architecture in a breeding program.

Soil salinity adversely affects plant growth and causes considerable losses in cereal crops. In this study, genetic variation in salinity tolerance was evaluated in sea barley (Hordeum marinum ssp. marinum). Based on plant growth-related traits, mineral nutrition and salt stress indices, lines with high yield under stress and non-stress conditions, or showing a small yield loss under salinity constraints, were identified. These lines will be useful for future breeding programs towards salinity tolerance in cereal crops.

CP23080Phenotypic characterisation and evaluation of resistance to Fusarium ear rot, fumonisin contamination and agronomic traits in a collection of maize landraces

Lorenzo Stagnati, Alessandra Lanubile 0000-0002-1868-4469, Giovanna Soffritti, Paola Giorni, Graziano Rossi, Adriano Marocco and Matteo Busconi
 

Finding new genotypes resistant to Fusarium infection represents an important goal for the improvement of maize cultivation. In this regard, a collection of maize landraces deriving from Emilia-Romagna (Italy) region was studied. These landraces represent starting resources crucial for broadening the genetic bases of maize and introducing new resistant alleles useful in breeding programs targeting multiple pathogens and their associated mycotoxins.

Wheat grown on soils contaminated by arsenic (As) may accumulate toxic levels of As in grains, allowing As to enter the human food chain. The study evaluated the effect of soil zinc (Zn) application on grain As and grain accumulation of Zn in two Zn-biofortified wheat cultivars grown on As-contaminated soil. Soil Zn application decreased grain As accumulation to below the permissible limit of 0.15 mg As kg−1 and simultaneously increased grain Zn accumulation.

CP23333Forage brassicas can enhance the feed base and mitigate feed gaps across diverse environments

Lucinda J. Watt 0000-0002-7388-7402 and Lindsay W. Bell 0000-0002-5064-2947
 

Long-term simulation modelling showed that autumn-sown forage brassicas can serve as a reliable and valuable forage source in drier environments across Australia’s crop–livestock zone. They have a long grazing window and stable production across a range of sowing dates and environments. Integrating forage brassicas into the existing feed base can reduce the frequency and magnitude of on-farm feed deficits in livestock production systems. They can also allow for a safe increase in stocking rates and reduce the need for supplementary feed.

Best pearl millet genotypes for recommendation to breeders, and use in breeding, are usually identified by evaluation in field trials in diverse environments. The main objective of this study was to assess genotypes based on mean performance across a multitude of environments. High iron and zinc lines with consistent performance across environments were identified and can be used in the development of biofortified hybrids.

CP23343Development of high-amylose maize (Zea mays L.) genotypes adapted to Indian conditions through molecular breeding

Arushi Arora, Deepak Bhamare, Abhijit Kumar Das 0000-0002-5816-2470, Shubhank Dixit, Sreya Venadan, Yathish K. R., Ramesh Kumar, Dharam Paul, J. C. Sekhar, Sunil Neelam, Sudip Nandi, M. C. Kamboj and Sujay Rakshit 0000-0001-6139-7943
 

Amylose is a type of resistant starch with numerous health benefits and industrial applications. Amylose content of normal maize starch is ~25%. We report the development of high-amylose maize (~50%) suited to Indian conditions through marker-assisted backcross breeding, using a high-amylose donor and high-yielding parental lines.

Path analysis (PA) is a multivariate statistical technique, widely used, however, when carrying out PA, the parameters of the mathematical model referring to the experimental design and the effects of the study factors are not considered. Therefore, this study aims to evaluate these possible impacts on PA results. Removing parameters from the mathematical model promotes changes in the direction and magnitude of the path coefficients, regardless of the type of PA performed.

CP23046Evaluating the Agricultural Production Systems sIMulator (APSIM) wheat module for California

Nicholas Alexander George 0000-0003-1687-7360, Helio de Jesus Pedro Cuamba, Mark E. Lundy and Sarita Jane Bennett 0000-0001-8487-7560
 

Globally, crop simulation models are important for increasing efficiency and broadening the scope of agricultural research and management. The APSIM crop model is widely used to simulate crop production but has not been widely tested for wheat systems in the western United States. In this study, we leverage existing state-wide field trials to evaluate the model and inform further research on model validation and calibration.


Cultivation of legume–cereal mixtures makes it possible to obtain high-quality fodder for livestock and increase crop biodiversity. The green fodder of the mixture with 75 + 25% or 50 + 50% share of field pea + spring triticale, respectively, contains high levels of total protein and amino acids, and provides high yields. The indicated mixtures can be successfully used in agricultural practice.

CP23252Root symbionts modify biomass of white clover (Trifolium repens) through changes in radiation interception and radiation-use efficiency

Magdalena Druille 0000-0001-6195-6303, Marina Rosso, Pablo A. García-Parisi 0000-0001-7725-9553, Martín Oesterheld and Marina Omacini 0000-0003-1460-262X
 

Root symbionts influence host plant growth, thereby affecting forage production, but their specific effects on the canopy’s ability to intercept radiation and convert it into plant biomass have remained elusive. We found that both arbuscular mycorrhizal fungi and rhizobia alter both components of the radiative model, and that the symbionts often display interactive effects. Therefore, root symbionts not only modify plant biomass but also significantly alter the structure and functioning of the canopy.

CP23241Single and co-inoculation of biofilm-forming rhizobacteria with macroalgae extract increase barley productivity in organic matter-limited soil

Sedat Çam 0000-0001-9030-6713, Çigdem Küçük, Sema Karakas Dikilitas, Göksal Sezen, Ahmet Almaca and Cenap Cevheri
 

A low level of organic matter in soils limits plant growth and productivity. Due to the negative impact of chemical fertilisers on living organisms, an alternative method for alleviating plant abiotic stresses has been of great interest in recent years. Roots can be inoculated with rhizobacteria that form a biofilm and promote plant growth. Inoculation with these strains in combination with macroalgae extract significantly increased barley productivity in organic matter-limited soil.

CP23198Ability of wheat genotypes to form large rhizosheaths may enhance survival of false-break events in rainfed production

Livinus Emebiri 0000-0002-5261-4552, Maheswaran Rohan, Shane Hildebrand and Wayne Pitt
 

Innovative technologies and management strategies are continually being developed to mitigate risks associated with climate change. We hypothesised that formation of a large rhizosheath may buffer wheat seedlings during extended false-break conditions to keep plants alive until the next rainfall. In glasshouse experiments with two soil types, the ability to form large rhizosheaths explained ~80% of the variability in crop establishment under various scenarios of false-break conditions.

CP23194Validation of critical soil-test phosphorus values from the Better Fertiliser Decisions for Pastures meta-analysis

David Weaver 0000-0003-1737-6680, David Rogers 0000-0002-0226-5956, Eric Dobbe, Robert Summers 0000-0002-3108-7562, Ronald Master, Robert McFerran, Graham Mussell, Justin Mercy, Luke Dawson and Kath Lynch
 

Stakeholders have challenged the relevance of critical soil-test phosphorus (P) values for pastures determined from the Better Fertiliser Decisions for Pastures (BFDP) meta-analysis to soils and contemporary pasture species in south-western Australia. We present results from 50 rate-response trials using contemporary pasture species compared with BFDP critical soil-test P values. The work should increase confidence in and use of critical soil-test P values in support of evidence-based P fertiliser advice, to minimise off-site impacts of P to waterways and plan fertiliser applications.
