Pea
The pea is an annual legume plant in the family Fabaceae, best known for its edible seeds and pods.
The pea is an annual legume in the Fabaceae family, grown for its edible seeds and pods. It played a key role in Gregor Mendel's genetics experiments.
What is a pea?
Peas are herbaceous annual plants with tendrils, compound leaves, and flowers in white, pink, purple, or red. They produce pods containing several seeds; some varieties are grown for edible pods. Originating in the Mediterranean and western Asia, peas have been cultivated for thousands of years.
Why grow peas?
Peas are a cool-season crop widely grown for food, animal feed, and soil improvement. They fix atmospheric nitrogen through root symbiosis with Rhizobium bacteria, making them valuable in crop rotations. Canada is a major producer, especially on the Prairies, for dry peas, processing, and export.
Scientific importance
Peas are a good source of protein, fibre, vitamins, and minerals. They are historically significant as the model organism for Gregor Mendel's experiments, which established the basic laws of inheritance and launched modern genetics.
In short
- Peas are legumes that fix nitrogen and improve soil fertility.
- They are a cool-season crop grown worldwide for food and feed.
- Peas were central to Mendel's genetics discoveries.
- Canada is a major pea producer, especially on the Prairies.
Canada is one of the major pea-producing countries and grows peas extensively on the Prairies, especially for dry pea, processing, and export markets.
