Drought substantially limits seed yield of common bean (Phaseolus vulgaris L.) in the tropics. Understanding interaction drought on and nutrient concentration is vital order to supply nutrition millions consumers who rely as a staple crop. Nevertheless, impact for both has not yet been concurrently investigated field environment. Using 10 bred lines developed by CIAT its partners their improved adaptation phosphorus deficiency, this study characterised leaf tissue grown field. significantly...
'QTL-hotspot' is a genomic region on linkage group 04 (CaLG04) in chickpea (Cicer arietinum) that harbours major-effect quantitative trait loci (QTLs) for multiple drought-adaptive traits, and it therefore represents promising target improving drought adaptation. To investigate the mechanisms underpinning positive effects of seed yield under drought, we introgressed this from ICC 4958 genotype into five elite cultivars. The resulting introgression lines (ILs) their parents were evaluated...
Low soil fertility commonly limits growth and yield production of common bean (Phaseolus vulgaris L.) in tropical regions. Impacts nutrient limitations on volume are well studied a major factor reducing crop yields. This study characterised the impact reduced supply carbon assimilation content leaf, phloem sap reproductive tissues grown controlled environment order to detect chemical markers for changes nutritional content. Leaf gas exchange measurements were undertaken over plant...
Abstract Mungbean ( Vigna radiata (L.) R. Wilczek var. ) is a significant food and cash crop grown in tropical subtropical regions. production consumer demand have increased substantially over the last two decades, owing to its agronomic, nutritional economic benefits. Despite breeding efforts expansion of mungbean various agro‐climatic regions, further hindered by low yield variability, which partly attributed impacts abiotic stress. Abiotic stress on physiology, morphology reproductive...
Abstract Key message There is variation in stay-green within barley breeding germplasm, influenced by multiple haplotypes and environmental conditions. The positive genetic correlation between yield across environments highlights the potential as a future target. Barley considered one of most naturally resilient crops making it an excellent candidate to dissect genetics drought adaptive component traits. Stay-green, thought contribute adaptation, which photosynthetic machinery maintained for...
Abstract Mungbean is an important sub‐tropical legume crop grown across Asia, Africa, and Australia. Yield improvement crucial for expanding production, but phenotyping traits diverse environments using current approaches challenging, limiting the scale complexity of information captured. High‐throughput platforms offer a solution by rapidly screening at scale. This study deploys unmanned aerial vehicle (UAV) platform to determine potential range agronomic physiological within mungbean...
Common bean (Phaseolus vulgaris L.) production in the tropics typically occurs rainfed systems on marginal lands where yields are low, primarily as a consequence of drought and low phosphorus (P) availability soil. This study aimed to investigate physiological chemical responses 12 bush genotypes for adaptation individual combined stress factors P availability. Water deficiency, both individually combined, decreased seed weight aboveground biomass by ∼80%. deficit deficiency photosynthesis...
The response of terahertz to the presence water content makes it an ideal analytical tool for hydration monitoring in agricultural applications. This study reports on feasibility sensing level freshly harvested leaves Celtis sinensis by employing a imaging platform based quantum cascade lasers and laser feedback interferometry. produces wide angle high resolution amplitude phase images at frame rates allowing dynamic transport other changes across whole leaf. complementary information...
A comprehensive understanding of key drivers grain yield is essential to identify opportunities improve productivity in mungbean (Vigna radiata (L.) Wilczek). The objective this study was assess and quantify physiological factors underpinning grown non-water-limiting conditions. Two field experiments, employing three genotypes (Jade-AU, Opal-AU Satin II) four canopy density treatments were conducted the summer growing season (Jan-Mar) 2019 2020 at Gatton campus, University Queensland,...
The use of carbon isotope abundance (δ(13)C) to assess plant acquisition and water has significant potential for in crop management improvement programs. Utilizing Phaseolus vulgaris L. as a model system, this study demonstrates the occurrence sensitivity fractionation during onset abiotic stresses between leaf phloem pools. In addition gas exchange data, compound-specific measures concentrations soluble components sap were compared with major carbohydrate sugar alcohol pools tissue....
Context Mungbean (Vigna radiata (L.) Wilczek) is an important grain legume for food, feed, and green manure. yield highly variable due to fluctuating temperature unpredictable rainfall. Aims To improve stability, it critical utilise a model that can simulate mungbean phenology, biomass, accurately. Methods A thorough understanding of the physiological determinants growth required advance existing crop modelling capability. Currently, there limited canopy reproductive development their...
Abstract Chickpea (Cicer arietinum L.) is one of the most important grain legumes in world, but its current and future production threatened due to increased incidence drought heat stress. To address this challenge, an integrated crop improvement strategy encompassing breeding, genomics, physiology agronomy required.

Abstract Mungbean is an important source of plant protein for consumers and a high-value export crop growers across Asia, Australia Africa. However, many commercial cultivars are highly vulnerable to biotic stresses, which rapidly reduce yield within the season. Fusarium oxysporum soil-borne pathogen that growing concern mungbean globally. This causes wilt by infecting root system resulting in devastating reductions. To understand impact on development productivity identify tolerant...
Context The grain-growing areas of north-eastern Australia are a major producer grain for human and livestock consumption, but declining soil nitrogen (N) phosphorus (P) fertility is increasing fertiliser requirements to sustain productivity. Adding concentrated zone P the subsoil (i.e. ‘deep P’ band) an effective strategy increase plant uptake in farming systems reliant on stored water. However, crop responses deep with contrasting N status remain unclear. Aim This study aimed assess...
