                <gco:CharacterString>This dataset documents the results of a 2024 field trial conducted by CSIRO at Tabbita, NSW, to evaluate the performance of long coleoptile wheat genotypes under varying sowing depths and soil conditions. The Excel file (.xlsx) contains 12 sheets, each representing a specific data type or collection date. The trial compared wheat genotypes sown at 4 cm and 10 cm depths, with some entries extending to 15 cm, across multiple replicates and ranges. The genotypes included standard and long coleoptile lines such as Mace, Mace18, Magenta, Magenta13, Gregory, Yitpi, Calibre, and Scepter, with suffixes indicating seed size or treatment (e.g., _sml, _std, _L, _S).

The dataset includes sowing layout maps, cone penetrometer readings taken on three dates (17th, 24th, and 30th May) to assess soil resistance at different depths, and multiple rounds of plant counts (28th May, 30th May, 5th June, 7th June, and 13th June) across different rows and depths. Elongation measurements were recorded on 28th and 30th May, with up to 10 readings per plot, providing data on early shoot growth. Final yield data is presented in the last sheet, including raw yield (kg) and adjusted yield per hectare (Ayld), calculated based on a 4 m plot length, 23 cm row spacing, and six harvested rows.

The dataset includes over 30 variables, such as genotype, sowing depth, plant counts per row, elongation measurements (ER1–ER10), and yield metrics. Codes like “Mace18_sml” denote genotype and seed size, while “4cm SD” and “10cm SD” refer to sowing depths. The data were collected using standard field protocols, with consistent plot dimensions and measurement intervals. This dataset enables analysis of genotype × environment × management interactions, particularly the influence of sowing depth and soil strength on emergence, early growth, and yield performance in long coleoptile wheat.</gco:CharacterString>
