Flowering abundance and duration — runner bean

Phaseolus coccineus L.

In runner beans, flowering abundance is a descriptive characteristic, while flowering duration is measured in days and can reach up to 100 days with regular harvesting.

In the reference 7 varieties crop Runner bean, where this is mentioned in the description.

For runner beans, phenological monitoring includes recording the start of flowering once 50–75% of flowers in the inflorescence have opened in the majority of plants. Based on flowering time, varieties are classified as early (up to 45 days from sowing), mid-season (45–65 days), and late (more than 66 days). Flowering abundance does not have a standardized scoring system and is considered a qualitative trait, which is highly dependent on environmental conditions.

The lifespan of an individual flower is 2–3 days, and that of a flower raceme is 10–14 days. The overall flowering period of the plant can last from June to September. For vegetable production, regular harvesting of young pods and the removal of spent racemes stimulate prolonged flowering, which can reach 100 days under favorable water and temperature conditions.
