Banana cultivars with fusarium wilt resistance

Fusarium wilt is a devastating fungal disease that affects banana plants. There are different races of the Fusarium fungus, and unfortunately, many popular banana cultivars, like the Cavendish banana (the one that dominates the global market), are susceptible to the highly virulent Tropical Race 4 (TR4). This race is spreading rapidly and poses a significant threat to banana production.

Here are some banana cultivars that show resistance to Fusarium wilt, particularly TR4:

Plantains (AAB genome group): Plantains are a staple food in many parts of the world, particularly Africa, Asia, and Latin America. They are a type of banana with a starchy texture and come in various cultivars. Research has shown that some plantains, particularly those from East Africa (East African Highland Bananas or EAHBs), exhibit resistance to TR4.

Calabasa (AAB genome group): This is another type of plantain that has shown some tolerance to TR4. It is known for its thick green skin and starchy flesh that is usually cooked before eating.

Silk bananas (AAB genome group): Silk bananas are known for their sweet and creamy flesh. While some Silk varieties are susceptible to TR4, there are reports of resistance in certain cultivars.

Wild bananas: Wild bananas, which are the ancestors of cultivated bananas, possess a wider range of genetic diversity compared to their domesticated counterparts. This diversity can include genes for disease resistance, including Fusarium wilt. Researchers are looking into ways to incorporate these resistance genes into cultivated bananas.

It’s important to note that Fusarium wilt resistance research is ongoing. While the cultivars mentioned above show some promise, there aren’t yet any commercially viable banana varieties with complete TR4 resistance that offer the same fruit quality and productivity as Cavendish bananas.

Is FHIA-01 fusarium wilt resistance?

Yes, FHIA-01 (Goldfinger banana) is considered tolerant/resistant to Fusarium wilt, but with some nuances:

Resistance Level: While not completely immune, FHIA-01 exhibits tolerance or resistance to Fusarium wilt, meaning it can experience the disease but to a lesser degree compared to susceptible cultivars. This translates to fewer symptoms and potentially slower disease progression.

Specific Race: The exact race of Fusarium wilt FHIA-01 resists isn’t explicitly mentioned in most sources. However, considering it was developed for subtropical regions, it likely offers resistance against the more common Race 1 that plagues these areas.

Field Performance: Reports suggest that FHIA-01 performs well in field trials against Fusarium wilt, particularly when compared to Cavendish bananas.
