Citrumelo

Citrumelo is a hybrid citrus fruit that is a cross between a pomelo and a grapefruit. It is also known as Citrus x paradisi in scientific terms. The fruit is primarily used in the production of rootstock for other citrus plants due to its resistance to certain diseases and pests.

History

The Citrumelo was first developed in the United States in the late 19th century as a response to the spread of Phytophthora spp., a type of water mold that was devastating citrus crops. The fruit's resistance to this and other diseases made it an ideal candidate for rootstock.

Characteristics

Citrumelo fruits are large and round, similar in appearance to a grapefruit. The skin is thick and rough, with a yellow to green color. The flesh is juicy and tart, with a flavor that is a blend of its parent fruits. However, due to its high acidity and bitter taste, it is rarely consumed fresh.

Cultivation

Citrumelo is primarily grown for its use as rootstock in the cultivation of other citrus fruits. It is particularly valued for its resistance to tristeza, a disease that has caused significant losses in citrus crops worldwide. In addition, it is also resistant to Phytophthora spp. and Diaprepes root weevil, making it a popular choice for growers.

Uses

While the fruit itself is not typically consumed due to its bitter taste, it is used in the production of marmalades and other preserves. The juice can also be used in cooking, where its tart flavor can enhance other ingredients.
