- Observation RPF3 retained a stable female-to-male ratio.
- Intervention effect RPF4 showed a 16% increase in female plants.
- Intervention effect RPF1 and RPF2 each showed a 10% increase in female plants.
- Association Seasonal changes significantly influenced seed yield.
- Observation RPF3 yielded 83.4 g/plant in season.
- Observation RPF4 yielded 81.6 g/plant in season.
- Intervention effect Secondary inflorescence seed production was reduced off season.
- Intervention effect RPF3 main inflorescence seed production increased 31%.
- Mechanism RPF4 offset per-plant yield decline by increasing female plant proportion.
- Observation In-season CGDD at harvest was 2434 °Cd.
- Observation Off-season CGDD at harvest was 2502 °Cd.
- Recommendation Authors recommend cultivar selection based on yield component stability and seasonal adaptability.
