Description Peanut or groundnut (Arachis hypogaea L.) is an annual herb, with geocarpic
fruits, and an indeterminate growth habit. It is classified as a legume in the plant
family Fabaceae. Carl Linneaus first described the cultivated species in 1753,
as A. hypogaea which was derived from the word “arachos” meaning a weed
and “hypogaea” which means an underground chamber (Stalker and Simpson,
1995). Cultivated peanut can be classified into two subspecies, fastigiata and
hypogaea, based on the presence or absence of floral axes on the main stem.
They can be further divided into six botanical varieties (subspecies hypogaea:
var. hirsuta, and var. hypogaea; subspecies fastigiata: var. aequatoriana, var.
fastigiata, var. peruviana, and var. vulgaris) based on a range of morphological
characteristics such as growth habit, trichomes, and pod morphology. Many
intermediates exist among these botanical types, therefore, the taxonomy is not
always clear (Stalker and Simpson, 1995). In 1969, Krapovickas postulated that
the variety hypogaea was the most ancient due to its runner type habit, no floral
spikes, and branching patterns which is similar to the characteristics of the wild
Arachis species (Krapovickas, 1969)...
