High Throughput Plant Phenotyping in Crop ImprovementKhushbu
Plant phenomics is a high-throughput path-breaking area that meets all the requirements for the collection of accurate, rapid and multi-faceted phenotypic data. Traditional phenotyping tools are generally low-throughput, labor-intensive, which limits high efficiency and are prone to human error (Atefi et al. 2021). High throughput phenomics (HTP) technologies are essential to avoid human error and to reduce time consumption while phenotyping large germplasm populations (Pasala and Pandey, 2020). HTP is an emerging area with numerous applications that combines plant biology, sensing technology and robotics aiding crop improvement programs. Plant phenomics is the study of plant growth, performance and composition. (Atefi et al. 2021)
Forward phenomics uses phenotyping tools to discriminate the useful germplasm having desirable traits among a collection of germplasm. This leads to identification of the ‘best of the best’ germplasm. Thus in reverse phenomics, we discover mechanisms which make ‘best’ varieties the best (Jitender et al. 2015).
High Throughput Plant Phenotyping under three scenarios: greenhouses and growth chambers under strictly controlled conditions; ground-based proximal phenotyping in the field and aerial based platforms (Araus et al 2018). Root system architecture (RSA) phenotyping in situ is challenging, RADIX (a rhizoslide platform used to screen the shoots and roots).
Application of plant phenotyping methods as a part of breeding programs has developed into an important research tool that facilitates breeders to develop cultivars with higher adaptability under different environmental conditions. Remote sensing with Unmanned Aerial Vehicles (UAVs ) has emerged as highly efficient and accurate used to determine crop performance and biomass estimation. Current advanced techniques include thermal, near-infrared sensing, fluorescence imaging, 3D scanning, RGB imaging, multispectral and hyperspectral sensing are lucratively used for plant growth and development identifcation, quantification and monitoring; disease monitoring and abiotic stress tolerance. The integration of crop functional structure with remote sensing, geography information systems, GPS technologies, cloud computing, decision support systems will promote the development of digital agriculture and provide technical support for modern agriculture (Song et al. 2021). The robust and user-friendly post-processing and analysis tools for processing and interpreting raw data are urgently needed and should be improved (Yang et al. 2020).

The workshop was organized by CIMMYT Global Conservation Agriculture Program (GCAP) and funded by the Bill & Melinda Gates Foundation (BMGF), the Mexican Secretariat of Agriculture, Livestock, Rural Development, Fisheries and Food (SAGARPA), the International Maize and Wheat Improvement Center (CIMMYT), CGIAR Research Program on Maize, the Cereal System Initiative for South Asia (CSISA) and the Sustainable Modernization of the Traditional Agriculture (MasAgro)
Heterotic group “is a group of related or unrelated genotypes from the same or different populations, which display similar combining ability and heterotic response when crossed with genotypes from other genetically distinct germplasm groups.”
Multiple inbred founder lines are inter-mated for several generations prior to creating inbred lines, resulting in a diverse population whose genomes are fine scale mosaics of contributions from all founders.

HIGH-THROUGHPUT PHENOTYPING METHODS FOR ECONOMIC TRAITS and DESIGNER PLANT TY...Komal Kute
A growing world population is expected to cause a "perfect storm" of food, feed, and biofuel. Under the climate change scenario, it is a challenge for agricultural scientists to ensure food and nutritional security for an ever-increasing population with limited and rapidly depleting resources. However, researchers are now observing that conventional breeding methods will not be sufficient to meet projected future demands for foods. To overcome these constraints, plant breeding has evolved over the past two decades towards a much closer integration of high-throughput phenotyping (HTP) tools and technologies.
The "phenotyping revolution" targets extremely precise and accurate measurements of very specific traits in large populations in the field. Sorghum breeding is not new to this advancement, which obviously implies significant shifts in the breeding programs. First, it indicates breeders integrate trait assessment with traditional yield and agronomic evaluation, emphasising that breeding programmes are opened up to new or other disciplines. It additionally requires that these new or other disciplines think about and conceptualise their own actions and orientations from the perspective of how they may fit into a breeding methodology. In this instance, the four primary sorghum breeding domains—staying green and transpiration limitation under high vapour pressure deficit (VPD); nodal root angle and depth; grain mineral content (Fe, Zn); and grain and stover quality traits—are tightly correlated with HTP. These ongoing initiatives focus on value of the particular trait and why it is considered by breeders; how it is measured with HTP approaches (method, throughput, cost, simplicity) and finally, how these traits are currently being embedded in the breeding program. Through various research, it became evident there are several other avenues of technology that, although not yet routinely implemented, could bring about a major benefit to the breeding programme’s endeavour to increase the rate of genetic gains. Here, we discuss the use of drone imaging for yield trial quality control and pinpoint plot heterogeneity, the integration of quality analysis into the assessment of agronomic traits in the field, and the use of X-ray spectroscopy to assess grain or crop architecture traits.
A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
A workshop hosted by the South African Journal of Science aimed at postgraduate students and early career researchers with little or no experience in writing and publishing journal articles.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
