Barley Synthesis Project Dataset

Barley, Australia's second most important crop, faces threats from climate change. With 9-10 million tonnes produced annually, only 30-40% achieves malting grade, with both grain yield and quality attributes impacted by abiotic stresses. Despite the relative adaptation of barley, Australian regions achieve just 35-60% of water-limited yield potential. Improved understanding of these production gaps and the genotypic, environmental and management factors will increase yield productivity nationally. A collaborative consortium was assembled to synthesise previous research and develop a national barley dataset to determine opportunities to optimise yield potential of barley in Australian farming systems. An industry forum was held on the 1-2 February 2023 to identify relevant barley datasets and prioritise research themes for further analysis and interpretation.

The Barley Synthesis Project Dataset comprises 132 trials collected from various sources, including NSW DPI, WA DPIRD, Birchip Cropping Group, GRDC National Trials, and the University of Adelaide in South Australia. The dataset is organised into two main research themes spanning from 2010 to 2022:

1.Optimal Flowering Period (84 Trials = 18,582 Records - 2011-2022)
2.Preserving Grain Quality (48 Trials = 10,890 Records - 2010-2016)

Each theme includes specific agronomic trait attributes relevant to its focus area. In addition to these core attributes, the dataset contains metadata fields that provide detailed information about each trial’s location, GPS coordinates, organisational ownership, and contact persons.

大麦是澳大利亚第二大重要作物，正面临气候变化带来的威胁。澳大利亚每年大麦产量达900万至1000万吨，但仅30%至40%的产品达到麦芽专用等级标准，籽粒产量与品质性状均受到非生物胁迫的影响。尽管大麦本身具备一定的适应性，但澳大利亚各产区仅能实现水分限制条件下潜在产量的35%至60%。深入厘清这类生产缺口及其背后的基因型、环境与管理调控因素，将有助于提升全国大麦的生产效率。本项目组建了跨机构协作联盟，旨在整合既往研究成果，构建国家级大麦数据集，以明确澳大利亚农业系统中大麦产量潜力的优化路径。2023年2月1日至2日，项目组举办了行业论坛，以遴选相关大麦数据集，并确定后续分析与解读的优先研究主题。

本次的大麦整合项目数据集（Barley Synthesis Project Dataset）共收录132项田间试验数据，数据来源包括NSW DPI、WA DPIRD、Birchip Cropping Group、GRDC National Trials以及南澳大利亚州的阿德莱德大学。该数据集按照两大核心研究主题进行组织，时间跨度覆盖2010年至2022年：
1. 最佳开花期（84项试验，共计18582条记录，时间跨度为2011-2022年）
2. 籽粒品质保持（48项试验，共计10890条记录，时间跨度为2010-2016年）

每个研究主题均包含与其研究方向匹配的专属农艺性状指标。除上述核心指标外，数据集还包含元数据字段，可提供每项试验的详细信息，包括试验地点、GPS坐标、所属机构以及联系人信息。
