🔍 Speciation and Domestication

Domesticated adzuki beans were first cultivated in Japan around 3000 BC, and it is likely that enlarged seeds occurred during the later Bronze Age or Iron Age periods with plough use.

The wild ancestor of this domesticated species is Vigna angularis var nipponensis, which can be found across Japan, Korea China Nepal Bhutan. Speciation between these two forms happened 50 thousand years ago; however, there are no records telling us how they were brought into cultivation-so far as we know though larger than average size populations still exist among today’s crops like soybeans dating back to 2000BC when farmers started cultivating Adzuki beans.

📖 Cultivation

The Japanese have been particularly interested in plant cultivation as evidenced by their long history of using it to improve crop yields and other aspects. One such example is the adzuki bean, which was one of their first crops subjectively bred for yields (yurukyara), colors (bburigakusei),and maturities(kikokushiryaku).

Breeding traits that are important include yield-bodied; purity of color tone/quality; maturity time span from planting to harvesting.

Important traits are yield, purity in color, and maturing time; there are also separate cultivars with smaller seeds for fodder or green manure purposes.

More than 300 landrace/breeders lines have been registered by China’s Institute For Crop Germplena.

🌱 Adzuki Beans Botany

The adzuki bean is a plant that can be either wild or cultivated. It is an annual herb usually between 30 and 90 centimeters high, but there are also climbing or prostrate forms of the plant.

The stem is green and sparsely pilose, and the root system is a taproot type that can reach a 40-50 cm depth. The leaves of the adzuki bean are trifoliate and pinnate, arranged alternately along the stem on a long petiole. Leaflets are ovate and about 5-10 cm long and 5-8 cm wide.

Adzuki flowers are papilionaceous and bright yellow and consist of six to ten (two to twenty) flowers. Pods are smooth, cylindrical, and thin-walled, changing from green to white or grey as they mature. Seeds are smooth and subcylindric, with a 5.0-9.1 mm length, a width of 4.0-6.3 mm, and a 4.1-6.0 mm thickness.

The thousand kernel weight is between 50 and 200 g. There are many different seed colors, from maroon to blue-black, mottled with straw.

The adzuki bean plant has hypogeal germination, meaning that the seedlings emerge from the ground 7-20 days after being planted. The plant's growth is slow compared to other pulses, and it typically reaches maturity between 80 and 120 days, depending on the cultivar and environmental conditions. Flowering lasts 30-40 days. The plant generally self-pollinates, but cross-pollination also exists.
