Bean vine growth habit

Phaseolus vulgaris L.

Bean vine growth habit is a qualitative characteristic of plant growth type that determines the stem's ability for prolonged vegetative development and the formation of twining shoots.

In the reference 319 varieties crop Common bean, where this is mentioned in the description.

In the variety testing of common bean (Phaseolus vulgaris L.), cultivars are classified into four main growth types according to the CIAT international classification. Type I is represented by determinate bush forms with limited stem growth, terminating in a flower raceme. Types II, III, and IV are indeterminate and are characterized by the ability for prolonged growth, ranging from erect bushes to prostrate and highly twining vine forms.

Evaluation of vine growth habit is conducted visually during the flowering stage based on the condition of the apical bud, internode length, and the stem's ability to twine. The presence of pronounced vine growth determines the agronomic cultivation practices: vining forms require the installation of supports and specific planting patterns to ensure aeration, whereas determinate forms are more suitable for mechanized harvesting.
