The apricot, which was cultivated in China and Central Asia as early as 2000 B.C., migrated with the country's traders, who traveled the Great Silk Road. The Chinese merchants, botanist Berthold Laufer suggests, very probably introduced the fruit to the Persians. They called it the "yellow plum" (zardaloo). Widely dispersed, it was spread throughout the Eurasian steppe by nomadic, horseback-riding tribesmen.
