Resistance to Fungal Diseases in Dark Red Norland Potatoes

Dark Red Norland potatoes offer a unique resistance profile to various fungal diseases. While they show susceptibility to some common potato diseases, they also have field immunity to one significant disease, making them a mixed choice for disease resistance. Here’s an overview of their resistance to key fungal pathogens:

Resistance to Gangrene: Dark Red Norlands have low to medium resistance to gangrene (Phoma foveata), a tuber rot that can cause decay during storage. While not highly resistant, they may benefit from careful handling, proper curing, and storage at cool, dry temperatures to minimize the risk of infection.

Resistance to Late Blight on Tubers and Foliage: Dark Red Norland potatoes have very low to low resistance to late blight (caused by Phytophthora infestans) on both tubers and foliage. Late blight can be particularly challenging, as it affects both the visible foliage and the underground tubers, potentially leading to significant crop loss in areas with humid conditions. To manage late blight, growers should use preventative measures like crop rotation, proper spacing, and, if necessary, fungicidal treatments.

Resistance to Powdery Scab: Dark Red Norlands also have very low to low resistance to powdery scab (Spongospora subterranea), a soil-borne disease that affects the appearance of tubers and can reduce market value. To help prevent powdery scab, avoid planting in infected soil and ensure good drainage, as wet conditions promote the spread of this disease.

Wart Disease (Field Immunity): One significant advantage of Dark Red Norland potatoes is their field immunity to wart disease (Synchytrium endobioticum). This disease can cause severe deformities in tubers, rendering them unmarketable, but wart is uncommon in areas with strict controls and healthy crop rotation practices. The immunity of Dark Red Norlands against wart disease provides peace of mind for growers concerned about this serious pathogen.

Resistance to Bacterial Diseases in Dark Red Norland Potatoes

Dark Red Norland potatoes exhibit strong resistance to key bacterial diseases, making them a resilient choice for growers concerned about bacterial pathogens. Here’s a closer look at their resistance profile:

Resistance to Blackleg: Dark Red Norland potatoes also exhibit high to very high resistance to blackleg (Erwinia spp.), a bacterial disease that affects the stems and tubers, causing decay and plant wilting. This strong resistance means Dark Red Norlands can withstand blackleg infections better than many other varieties, reducing the chances of crop loss due to this disease. Ensuring proper field hygiene and avoiding wet, poorly drained soils can further support this variety’s resilience against blackleg.

Resistance to Common Scab: Dark Red Norland potatoes have medium to very high resistance to common scab (Streptomyces scabies). Common scab affects the tubers’ skin, creating rough, scabby patches that can detract from their appearance and marketability. With this level of resistance, Dark Red Norland potatoes are less likely to develop severe scab symptoms, even in soil with moderate pathogen presence. To further minimize the risk of scab, avoid overly dry soil conditions, as Streptomyces scabies thrive in dry, alkaline soils.

Resistance to Viral Diseases in Dark Red Norland Potatoes

Dark Red Norland potatoes exhibit a favorable resistance profile against several common potato viruses. This resilience against viral pathogens adds to their reliability as a productive and healthy crop. Here’s a summary of their resistance to key viruses:

Resistance to Potato Leaf Roll Virus (PLRV): Dark Red Norland potatoes have medium to high resistance to potato leaf roll virus (PLRV). PLRV can cause leaf curling, stunted growth, and tuber quality reduction. With this level of resistance, Dark Red Norlands are moderately protected from PLRV, though occasional infection may still occur, especially if aphid populations, which spread the virus, are high.

Resistance to Potato Virus A: Dark Red Norland potatoes have high to very high resistance to potato virus A (PVA). PVA can cause leaf mottling and reduced plant vigor, but with this strong resistance, Dark Red Norlands are less likely to experience significant symptoms or yield losses due to PVA.

Resistance to Potato Virus Y: These potatoes exhibit medium to high resistance to potato virus Y (PVY). PVY can cause leaf yellowing, stunted growth, and tuber damage, depending on the strain. While Dark Red Norlands are not completely resistant, their medium to high resistance helps protect them from severe PVY outbreaks, reducing the need for extensive virus management.

Resistance to Pests in Dark Red Norland Potatoes

Dark Red Norland potatoes show low resistance to several common nematode pests, specifically the Globodera species, commonly known as potato cyst nematodes (PCN). Here’s a breakdown of their pest resistance:

Resistance to Globodera pallida Races 1, 2, and 3: Dark Red Norlands have very low to low resistance to Globodera pallida races 1, 2, and 3. G. pallida, another potato cyst nematode species, can lead to root damage and hinder tuber development. With low resistance to all three races, these potatoes are particularly vulnerable, and soil treatments, resistant rotation crops, and careful monitoring are recommended to minimize the impact of G. pallida infestations.

Resistance to Globodera rostochiensis Race 1: Dark Red Norland potatoes have very low to low resistance to Globodera rostochiensis Race 1. This nematode is a significant pest in potato-growing regions and can cause substantial crop damage by feeding on potato roots, reducing plant vigor and yield. Given their susceptibility, growers should practice crop rotation and consider nematode-resistant cover crops to manage infestations.
