Late blight, caused by the Phytophthora infestans fungus, can significantly impact the plant’s leaves and stems, leading to reduced yields. Given the low resistance in the foliage, it’s important to take preventive measures, such as using fungicides or selecting disease-resistant varieties, to manage this threat.
Resistance to Dry Rot (Fusarium coeruleum):
Bonanza potatoes exhibit high resistance to dry rot caused by Fusarium coeruleum. Dry rot is a common fungal disease that affects stored tubers, leading to soft, decaying areas. The high resistance to this disease ensures that Bonanza potatoes maintain better quality during storage, reducing the likelihood of spoilage.
Wart (Synchytrium endobioticum):
Bonanza potatoes are field immune to wart (Synchytrium endobioticum), a serious fungal disease that causes the formation of warty growths on tubers. This immunity makes Bonanza breed potatoes a great choice for growers in regions where wart disease is a concern, helping to prevent the spread of the pathogen to other crops.
Resistance to Gangrene (Phoma foveata):
Bonanza potatoes show medium to high resistance to gangrene caused by Phoma foveata. Gangrene can affect the tubers, causing them to rot and degrade in quality. With this level of resistance, Bonanza seed potatoes are less likely to suffer from gangrene, which helps maintain both yield and tuber quality.
Resistance to Dry Rot (Fusarium spp.):
Bonanza potatoes also demonstrate high resistance to dry rot caused by other Fusarium species. This characteristic is particularly valuable for ensuring that the tubers remain healthy during storage, preventing the onset of rot that could affect their usability and market value.
Resistance to Bacterial Diseases in Bonanza Potatoes
Bonanza potatoes display a medium to high resistance to bacterial diseases, which is important for ensuring the overall health and quality of the crop. One of the most common bacterial diseases affecting potatoes is common scab, caused by Streptomyces scabies. Here’s an overview of Bonanza potatoes’ resistance to bacterial diseases:
Resistance to Common Scab (Streptomyces scabies):
Bonanza potatoes have medium to high resistance to common scab, a bacterial disease that affects the tubers and causes rough, scabby lesions on the skin. These lesions can affect the appearance of the potatoes, making them less marketable, though the internal quality remains unaffected. Bonanza breed potatoes’ moderate to high resistance to this disease helps reduce the severity of scab formation, resulting in healthier-looking tubers with fewer cosmetic blemishes.

Resistance to Virus Diseases in Bonanza Potatoes
Bonanza potatoes have varying levels of resistance to different virus diseases that can affect potato crops. Understanding these resistance characteristics is key for growers looking to manage and minimize the impact of viral infections. Here’s a closer look at how Bonanza breed potatoes fare against some common virus diseases:
Resistance to Potato Virus A (PVA):
Bonanza potatoes exhibit medium resistance to Potato Virus A (PVA). This virus can cause symptoms like mosaic patterns and stunted growth, which can negatively impact yields. The moderate resistance in these potatoes helps reduce the severity of the infection, but monitoring and management are still important to control the spread of the virus.
Resistance to Potato Virus X (PVX):
Bonanza potatoes have low resistance to Potato Virus X (PVX). This virus typically causes mild symptoms such as mosaic patterns on the leaves, but it can also lead to reduced tuber quality and yield losses if not managed effectively. With low resistance, Bonanza breed potatoes may be more susceptible to PVX, and growers should be vigilant in preventing its spread through aphids or infected seed potatoes.
Resistance to Potato Virus Y (PVY) (Strain Not Specified):
Bonanza potatoes show high resistance to Potato Virus Y (PVY), which is one of the most damaging potato viruses. PVY can cause leaf curling, yellowing, and mosaic patterns, and it can significantly reduce yield and tuber quality. Bonanza’s high resistance to this virus is a major benefit, as it helps protect the crop from severe viral damage, ensuring better overall productivity.
Resistance to Potato Leaf Roll Virus (PLRV):
Bonanza potatoes have medium resistance to Potato Leaf Roll Virus (PLRV). PLRV can cause leaves to curl, roll, and become deformed, impacting photosynthesis and reducing yield potential. The medium resistance in these potatoes offers some protection, but additional measures such as controlling aphid populations (which transmit the virus) may still be necessary.
Resistance to Pests in Bonanza Potatoes
Bonanza potatoes have certain vulnerabilities when it comes to resistance against specific pests, particularly nematodes that can cause significant damage to potato crops. Understanding these resistance levels is crucial for effective pest management. Here’s an overview of how Bonanza breed potatoes fare against some of the most common pest threats:
Resistance to Globodera rostochiensis Race 1 (Golden Cyst Nematode):
Bonanza potatoes show low resistance to Globodera rostochiensis race 1, also known as the golden cyst nematode. This pest infects potato roots, forming cysts that can damage the plants and reduce tuber yield. With low resistance, these potatoes are more susceptible to this nematode, so growers should take proactive measures to control it, such as crop rotation or using resistant rootstocks.
Resistance to Globodera pallida Race 1 (Pale Cyst Nematode):
Bonanza potatoes also have low resistance to Globodera pallida race 1, the pale cyst nematode. Like the golden cyst nematode, this pest attacks the roots and can cause severe damage to the plants. Given the low resistance, controlling this pest becomes essential for maintaining healthy crops, especially in areas where Globodera pallida is prevalent.
Resistance to Globodera pallida Race 2 (Pale Cyst Nematode):
Similarly, Bonanza potatoes exhibit low resistance to Globodera pallida race 2, another variant of the pale cyst nematode. The low resistance to this pest means that Bonanza breed potatoes may be at risk of damage, which can lead to a reduction in both yield and tuber quality. Again, management strategies such as crop rotation and nematode-resistant varieties should be considered to mitigate this risk.
Conclusion
Bonanza potatoes are a versatile variety with moderate to high resistance to several diseases and pests, making them a solid choice for many growers. They have good resistance to virus diseases like Potato Virus Y and high resistance to dry rot and wart. However, they show low resistance to late blight on foliage and several nematodes, such as Globodera rostochiensis and Globodera pallida. While they are resistant to some fungal and bacterial diseases, managing virus and pest threats is still necessary to ensure healthy, high-yield crops.
