The orange is the fruit of the citrus species Citrus sinensis in the family Rutaceae. It 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
The orange is a hybrid between pomelo (Citrus maxima) and mandarin (Citrus reticulata). The chloroplast genome, and therefore the maternal line, is that of pomelo. The sweet orange has had its full genome sequenced.
Oranges are the most popular among all the citrus fruits. This tangy fruit definitely impresses with its delicious juicy taste and its high concentration of vitamin C as well as other nutrients. Oranges are widely popular and account for about 70% of the world’s citrus production. Their amazing taste not only makes them a popular snack but also a major ingredient in several dishes. Even the orange peel contains volatile oil glands in pits which have several health benefits. Orange juice is widely used as a preservative as well as to impart flavor to various dishes.
