- Association Early Adzukibean varieties showed less sensitivity to short days than late varieties.
- Association The intermediate M 2 group had flowering dates that varied especially with temperature.
- Association Manchurian ecotypes were slightly more sensitive to short days than Hokkaido ecotypes.
- Observation Under stronger short days, temperature thresholds for flowering did not differ among varieties.
- Association Under long days, temperature thresholds for flowering increased with varietal lateness.
- Observation Flowering dates did not differ among varieties under short days.
- Mechanism Differences in sensitivity to daylength appeared as differences in flowering delay under long days.
- Association Varietal earliness and daylength sensitivity had matching orders.
- Recommendation The authors propose earliness testing as a practical substitute for testing daylength sensitivity.
