Other claims from this paper (19)
- Observation Under well-watered conditions H77/833‐2 had higher seed number than PRLT 2/89‐33 and introgression lines.
- Observation Under well-watered conditions H77/833‐2 had higher yield than PRLT 2/89‐33 and introgression lines.
- Intervention effect At 0.3 FTSW, H77/833‐2 stover biomass fell 45%.
- Intervention effect At 0.3 FTSW, H77/833‐2 seed number fell 60%.
- Intervention effect PRLT 2/89‐33 biomass decreased 20% under increasing water stress.
- Intervention effect PRLT 2/89‐33 seed number decreased 25% under increasing water stress.
- Intervention effect H77/833‐2 100-seed weight decreased only 20% under stress.
- Intervention effect Tolerant 863B maintained higher seed number than 841B under water stress.
- Intervention effect Tolerant 863B maintained higher biomass than 841B under water stress.
- Intervention effect PRLT 2/89‐33 grain filling duration was similar to H77/833‐2 under well-watered conditions.
- Intervention effect Introgression-line grain filling duration was similar to H77/833‐2 under well-watered conditions.
- Intervention effect PRLT 2/89‐33 grain filling lasted longer than H77833‐2 under water stress.
- Intervention effect Introgression-line grain filling lasted longer than H77833‐2 under water stress.
- Intervention effect Seed growth of 863B lasted longer than that of 841B under water stress.
- Mechanism The authors attribute stress-tolerant lines’ higher seed yield to retention of more seeds.
- Observation Genotypes with fewer, larger panicles and larger grains better withstood post-anthesis stress.
- Observation The introgression line inherited part of the tolerant phenotype.
- Mechanism The terminal drought QTL may help maintain higher seed number and 100-seed weight.
- Mechanism Continued stover biomass gain through tillering in well-watered H77/833‐2 may signal resource competition with grains.
