Phenotyping of barley genotypes for resistance to P. thornei, 2015-2018

Full description

This dataset contains four separate experiments conducted between 2015 and 2018 that phenotyped barley genotypes for their resistance to the root-lesion nematode (P. thornei). All experiments were grown in glasshouses located at the Leslie Research Facility, Toowoomba QLD, using the methods described by Thompson et al. (2020) https://www.ncbi.nlm.nih.gov/pubmed/31680650. Two experiments, namely 2017x01 and 2018x01, include genotypes from project DAQ00188 (NVT). The primary data metric is P. thornei/kg of oven-dry soil and root (PTKG) with supporting metrics: tiller number (Tiller), plant height in cm (Height), plant maturity on Zadoks scale (Maturity), plant top dry weight in grams (TDWT), soil moisture content per cent (SMC) and trial notes. Environmental/Experimental Conditions: Air and soil temperature: 20–25°C Bottom watering system: 2 cm tension. Data file: "Sheedy USQ barley Pratylenchus thornei resistance data 2012_23 standardised for GRDC v2.csv" Content: Standardised raw data from glasshouse experiments assessing barley resistance to P. thornei. Processing: Data compiled using Microsoft 365 Copilot GPT-4 Turbo from Excel summary file. Quality assurance: CV and heritability calculated; genotype rankings validated against long-term data. Standards: Resistance standard genotypes included in each experiment. Principal variable: PTKG = P. thornei per kg oven-dry soil and roots (loge(x) transformed). Other variables: UID, Exp, Year, Orig_Genotype, Exp_UID, Col, Row.
