According to the origin of the varieties, they are divided into local varieties and cultivated varieties. Local varieties have poor uniformity of agronomic traits, but have good adaptability to the local area, especially strong resistance to stress. The cultivated varieties have specific commercial characteristics and cultivation response, and have high uniformity of botanical and agronomic traits.
According to grain size, it can be divided into small grain type (100 grain weight is less than 70 grams), medium grain type (100 grain weight is 70-120 grams) and large grain type (100 grain weight is more than 120 grams). ; According to the color of the seed coat, they are divided into 4 types: green-skinned (green-skinned) beans, white-skinned (milky-white) beans, red-skinned (purple-skinned) beans and black-skinned beans.
According to the purpose, it is divided into edible type (fresh vegetable type, dry grain processing type), feeding type (green feed and dry feed) and green manure type. According to the length of the pod, it can be divided into long pod type (pod length more than 10 cm) and short pod type (pod length less than 10 cm); according to the ability to withstand low temperature in the seedling stage, it can be divided into autumn sown broad beans (winter broad beans). and spring-sown broad beans (spring broad beans); according to the length of their maturity period, they can be divided into early-maturing, medium-maturing and late-maturing types.
