New research into crop disease resistance in oilseed rape by a research team at the University of Hertfordshire has been published online this week by journal PLOS ONE.

Protecting crops from catastrophic yield losses caused by plant pathogens is a major goal of agriculture to safeguard global food security in response to growing concerns about food shortages and climate change.

Use - Crop - Resistance - Methods - Crop

Use of crop resistance is one of the most economical methods of controlling crop diseases. Phoma stem canker, also known as blackleg disease, is a disease responsible for annual losses worth more than £1,000 million in oilseed rape crops across the world. The disease is caused by the fungal pathogen Leptosphaeria maculans. The pathogen first infects the leaves of oilseed rape in autumn (October/November), causing phoma leaf spot lesions, then grows symptomlessly along the leaf midrib and petiole to reach the stem, causing damaging phoma stem cankers in spring/summer (April-July) that result in yield losses.

Currently, selection of cultivars with quantitative resistance has relied on assessment of crop disease severity at the end of growing season. It has been difficult to investigate quantitative resistance against the growth of this pathogen in leaves and petioles...
