A controlled environment assay for the rapid evaluation of verticillium stripe resistance in canola

Abstract

Abstract Verticillium stripe disease is an emerging threat to canola production in Western Canada. Accurately assessing verticillium stripe resistance in breeding germplasm collections is crucial for identifying sources of genetic resistance. Currently, field phenotyping is the most widely used method for evaluating verticillium stripe resistance; however, achieving uniform disease pressure under field conditions presents significant challenges. Here we report a novel controlled environment (CE) soil-less assay for the rapid evaluation of verticillium stripe resistance in canola. The CE results were validated in a field trial which showed a strong correlation between the field data and the CE results. This cost-effective and time-efficient assay enables accurate assessment of verticillium stripe symptoms in a one-month testing cycle.

Code and data availability

The paper describes a controlled-environment verticillium stripe assay for canola with CE and field disease severity data, but no public phenotype dataset, image/sensor inputs, analysis code, or trained model is deposited or referenced. The only URLs mentioned are the bioRxiv preprint itself, a general Canadian plant疾病
