Marsh - Like the Duncan externally and internally, the flesh of the Marsh variety is firm and has a high juice content. During recent years, the Marsh has almost completely replaced the Duncan largely due to its ability to remain on the tree for significantly longer thus, prolonging the harvest period. The Marsh white grapefruit is highly desirable for processing due to the attractive balance between sweetness and acidity, and the segment stability that is characteristic of the variety.

Duncan - Larger and slightly more resistant than the Marsh, the flesh of the Duncan white grapefruit is typically firm, with high juice content. Though primarily grown in Florida, Israel, Cuba, Mexico and South Africa also produce large quantities.

Star Ruby - The Star Ruby is currently the most deeply pigmented variety of grapefruit commercially available and is widely considered to be the best pigmented variety available. Both the interior and exterior of the fruit are strongly coloured, and the desirability of the fruit is increased by the high sugar and juice content of the flesh. Despite the attractive characteristics of the fruit, the production of the variety Star Ruby is still relatively small in comparison with other varieties due to the sensitivity of the tree to disease and climatic changes.

Rio Red - Later maturing and slightly lighter in colour than the Star Ruby variety the Rio Red is considered attractive due to the soft and exceptionally juicy nature of the flesh and the lack of seeds (normally 1-3) as well as an intense interior colour that is surpassed only by Star Ruby. Producers devote more of their production to Rio Red than Star Ruby due to the increased ability to withstand disease and adverse weather conditions.

Ruby Red - In terms of fruit characteristics, the Ruby Red is extremely similar to the Marsh variety and is desirable due to the low number of seeds in each fruit. Despite new varieties, Ruby Red continues to be the most well-recognised variety worldwide.

Ray Ruby - Almost identical to the Ruby Red variety, the Ray Ruby has a more intense blush and internal colour, though these difference do not become apparent until mid season. Due to these factors and a higher sugar (brix) content, Ray Ruby is considered superior to Ruby Red and the juice is more attractive.

Flame - This variety is attractive due to its capacity to remain on the tree without deteriorating significantly. Aesthetically, the Flame grapefruit is perhaps the most impressive of the pigmented varieties, being almost uniformly round, with strong exterior blushing that is almost equal to Rio Red and Star ruby and an intense internal colour. As with other desirable pigmented varieties, Flame grapefruit typically has high juice content.
