Other claims from this paper (10)
- Observation Aboveground dry matter was similar for the near isogenic lines and Arina at anthesis and medium milk stage.
- Observation Dry matter accumulation diverged only after the medium milk stage.
- Observation At maturity, the near isogenic lines yielded 12% less grain than Arina, with a 5 to 14% range.
- Observation The near isogenic lines had 3 to 11% fewer grains per square meter.
- Observation The near isogenic lines had 2 to 7% lower mean grain weight.
- Observation The smaller grain number was associated with 6% fewer tillers per plant.
- Observation The smaller grain number was associated with 2% fewer grains per ear.
- Mechanism Reducing grains per ear suggested that reduced assimilate supply contributes to lower yield in the near isogenic lines.
- Mechanism Reducing grains per ear suggested that diminished capacity to incorporate assimilates in grain contributes to lower yield.
- Association Small differences among Lr9 lines suggested a direct relationship between yield depression and Lr9 resistance.
