Orange, To Distinguish It From The Related Citrus × Aurantium, Referred To As

The orange is a hybrid fruit originating from Southern China, Northeast India, and Myanmar. It is the fruit of the Citrus x sinensis species, which reproduces asexually through nucellar embryony. The orange is a cross between the pomelo and mandarin, with its chloroplast genome coming from the pomelo. Oranges are one of the most widely cultivated fruit trees in the world, with 73 million tonnes grown globally in 2017 and Brazil being the largest producer.

The orange is the fruit of various citrus species in the family Rutaceae (see list of plants

known as orange); it primarily refers to Citrus × sinensis,[1] which is also called sweet


orange, to distinguish it from the related Citrus × aurantium, referred to as bitter orange. The
sweet orange reproduces asexually (apomixis through nucellar embryony); varieties of sweet
orange arise through mutations.[2][3][4][5]
The orange is a hybrid between pomelo (Citrus maxima) and mandarin (Citrus reticulata).[2]
[6]
 The chloroplast genome, and therefore the maternal line, is that of pomelo.[7] The sweet
orange has had its full genome sequenced.[2]
The orange originated in a region comprising Southern China, Northeast India,
and Myanmar,[8][9] and the earliest mention of the sweet orange was in Chinese literature in
314 BC.[2] As of 1987, orange trees were found to be the most cultivated fruit tree in the
world.[10] Orange trees are widely grown in tropical and subtropical climates for their sweet
fruit. The fruit of the orange tree can be eaten fresh, or processed for its juice or
fragrant peel.[11] As of 2012, sweet oranges accounted for approximately 70% of citrus
production.[12]
In 2017, 73 million tonnes of oranges were grown worldwide, with Brazil producing 24% of
the world total, followed by China and India.[13]
