Origin Story

Discovered as a chance seedling in Texas in the early 20th century, the Marrs Orange gained commercial recognition around the 1930s. Though its exact breeder and parentage remain undocumented, it is believed to be a spontaneous mutation of Citrus sinensis, possibly linked to the Valencia group but genetically distinct due to its unique acid-sugar balance.

Classification

The Marrs Orange belongs to the sweet orange species, Citrus sinensis, within the Rutaceae family. It is classified as a cultivar of sweet orange, distinct for its low acidity and sweetness, and is sometimes grouped commercially among fresh-eating oranges rather than juicing or processing types.

Appearance or Form

Marrs Oranges are medium to large fruits, typically measuring 7 to 9 centimeters in diameter and shaped slightly oval. Their bright orange rind is smooth and relatively easy to peel. Inside, the flesh is deep orange, tender, and extremely juicy, characterized by very low acidity and a high sugar content that imparts a mild, sweet flavor.

Behavior or Usage

Primarily valued for fresh consumption, Marrs Oranges are favored by those who prefer mild, sweet citrus without tartness. They are commonly sold in regional markets across Texas and California. While their juice is prized for drinking, the low acidity limits their use in commercial juice blends and marmalade production, where acidity is important for flavor and gelling.
