Cac Mango

Cac Mango (Mangifera ‘Cac’) — Comprehensive Cultivar Profile

Origin & Background:
• The Cac mango (often spelled Cát in Vietnamese) is a popular mango cultivar originally from Vietnam, where it has been selected and grown for many years before being introduced to the U.S. and other tropical/subtropical regions. In Vietnam it’s closely associated with names like Xoai Cat Chu (or similar regional names).
• The cultivar has become well-regarded among Florida backyard growers and mango enthusiasts for its fruit quality and overall performance in a humid climate.

Tree Characteristics & Growth Habit:
• Size & Habit: Cac mango trees are medium to large, with a vigorous and spreading growth habit that produces an open, sometimes leggy canopy. Regular shaping and pruning are recommended to keep size manageable (often maintained around 15–20 ft with pruning).
• Production: Trees tend to be consistent and heavy producers once established, providing reliable seasonal yields.
• Seed Type: Polyembryonic, meaning seedlings can produce trees similar to the parent under ideal conditions, though most growers graft for true-to-type performance.

Fruit Description:
• Ripening Season: Mid-season, generally late June into July (in Florida and similar climates).
• Size & Shape: Fruit are medium to large (often around 1–1.5 lbs), heart-shaped or ovate with smooth skin that is greenish/yellow when ripe.
• Skin & Flesh: Smooth, relatively thin skin and fiberless, vibrant yellow-orange flesh.
• Flavor Profile: Cac’s eating quality is one of its strongest attributes. The flavor is typically described as rich, sweet, aromatic, and complex, often with citrus, peach, melon, or floral notes and a balanced acidity that complements its sweetness. Some growers even describe subtle cola-like undertones.

Disease Resistance & Susceptibility:
• Anthracnose: Cac mango exhibits good resistance to anthracnose, an important fungal disease affecting mango flowers and fruit in humid climates.
• Bacterial Spot: It has very good resistance to bacterial spot, another common disease in mangoes that can affect leaves and fruit.
• Powdery Mildew: The flowers can be susceptible to powdery mildew, especially under humid conditions where that disease thrives, so some growers monitor and manage accordingly.
• Overall: Compared to many Indochinese-type mangoes, Cac is regarded as disease-tolerant and less demanding than many other cultivars — one reason it’s gained popularity with home growers.

General Notes & Growing Tips:
• Cac thrives in warm, humid subtropical climates with full sun and good soil drainage — conditions similar to its native Vietnam growing environment.
• The vigorous growth and open canopy mean regular pruning is key to maintaining manageable size and encouraging healthy fruiting.
• Because of its excellent eating quality and reliable disease resistance, it’s often recommended for home mango collections where flavor and tree performance are priorities over commercial shipping traits.

Summary:
The Cac mango is a Vietnamese-origin Indochinese cultivar beloved for its rich, aromatic, fiberless fruit, consistent production, and above-average disease resistance — especially to bacterial spot and anthracnose — with only moderate susceptibility to powdery mildew under certain conditions. Its vigorous tree habit and superb eating quality make it a favorite choice for backyard and dooryard mango growers who are willing to manage its size for long-term enjoyment
