Mother of all citrus: Oranges, grapefruit, lemons and limes all descended from single ancestor

Oranges, grapefruit, lemons and limes are all hybrids, mixed and matched from 10 “wild” citrus species descended from a single Asian ancestor some eight million years ago, scientists said….

A global team of scientists sequenced the genomes of 60 citrus varieties to draw up a family tree going to the very root of one of the world’s best-loved fruit groups.

They traced the mother of all citrus to the southeastern foothills of the Himalayas in the late Miocene period, study co-author Guohong Wu of the US Department of Energy Joint Genome Institute told AFP.

That specimen, he said, likely resembled a present-day, inedible “papeda” — a bitter, sour fruit.

From this source emerged 10 wild or “natural” species — including the pummelo, wild mandarin, and a type of kumquat.

Some of the ten are extinct.

“All other citrus types, including the economically important cultivars (oranges, grapefruits, lemons, limes) are hybrids derived from two or more of the… 10 pure species,” Wu said by email.
