Pea (pisum in Latin) is a pulse, vegetable or fodder crop, but the word often refers to the seed or sometimes the pod of this flowering plant species. Carl Linnaeus gave the species the scientific name Pisum sativum in 1753 (meaning cultivated pea).
Pods of the edible-podded pea, including snap peas, do not have a membrane and do not open when ripe. At maturity, the pods grow to around 4 to 8 centimetres (1 + 1 ⁄ 2 to 3 inches) in length. Pods contain three to nine peas. The plants are climbing, and pea sticks or a trellis or other support system is required for optimal growth.

Ascochyta pisi also infects 20 genera of plants and more than 50 plant species including soybean, sweet pea, lentil, alfalfa, common bean, clover, black-eyed-pea, and broad bean. [2] Field pea is an annual, cool season legume that is native to northwest and southwest Asia.

Snow peas have the thinner walls of the two edible pod variants. Two recessive genes known as p and v are responsible for this trait. [11] p is responsible for reducing the sclerenchymatous membrane on the inner pod wall, while v reduces pod wall thickness (n is a gene that thickens pod walls in snap peas). [13]
