What is the peanuts closest relative?

The closest relative of peanuts (Arachis hypogaea) is the genus Arachis itself, particularly species like Arachis duranensis and Arachis ipaensis, which are wild relatives of cultivated peanuts. These species contribute to the genetic diversity and breeding potential of peanuts. Additionally, peanuts belong to the legume family (Fabaceae), which includes other crops like beans and lentils, but within the Arachis genus, the wild species are the closest relatives.
