Maturity Group — Scarlet Runner Bean

Phaseolus coccineus L.

There are no standardized maturity groups for scarlet runner beans. Maturity assessment is conducted through phenological indicators, such as the number of days from sowing to flowering, and by distinguishing between technical and biological stages of pod readiness.

In the reference 36 varieties crop Runner bean, where this is mentioned in the description.

In scarlet runner beans, harvest readiness is determined by the intended use. Technical maturity is characterized by the state of the pods while they remain tender and succulent without coarse fibers, whereas biological maturity is achieved upon the full formation of seeds and a reduction in moisture content to a minimum.

This species is characterized by extended and uneven pod ripening, which precludes the use of standard maturity intervals. The duration of the growing season is highly dependent on temperature conditions, and critical sensitivity to frost requires the monitoring of timelines before the onset of autumn.
