Seenhaigustevastane

Seenhaigustevastane is an Estonian term referring to resistance to fungal diseases. In agricultural and horticultural contexts, it describes a cultivar, line, or species that shows reduced susceptibility to one or more fungal pathogens, such as rusts, mildews, or blights. The concept covers both qualitative resistance, typically controlled by major resistance genes, and quantitative or polygenic resistance, which is governed by many genes contributing partial protection.

Seenhaigustevastane is a key objective in plant breeding and crop protection. It can be achieved through traditional breeding, marker-assisted selection, and increasingly through biotechnological approaches. Management practices that reduce infection pressure, such as optimized planting times, crop rotation, and balanced fertilization, often complement genetic resistance. Evaluation of resistance involves controlled inoculation trials and field assessments, with metrics including disease incidence, severity, and the area under the disease progress curve (AUDPC).

Durability is a central concern, as pathogens can adapt to overcome resistance. Breeding strategies to enhance longevity include pyramiding multiple resistance genes, combining qualitative and quantitative resistance, and deploying resistant varieties strategically within landscapes. Seenhaigustevastane is applicable to a range of crops and ornamentals, and may also refer to post-harvest resistance to fungal decay.

Overall, seenhaigustevastane represents an important trait for reducing yield losses, limiting fungicide use, and sustaining crop productivity in the face of evolving fungal threats.
