Other claims from this paper (15)
- Association Yield rose with year of cultivar release by 25 ± 3.4 kg/ha per year.
- Association Harvest index increased across 1958–2007.
- Association Shoot biomass increased among varieties released after the early 1980s.
- Association Grain size decreased between 1957 and 1982.
- Association Grain size increased after 1982.
- Association Grain size plasticity increased twofold after 1982.
- Association Grain number increased until the early 1980s.
- Association Grain number stabilized after the early 1980s.
- Association Grain number was associated with crop growth rate between stem elongation and anthesis.
- Association Grain size was associated with crop growth rate per grain.
- Association Crop growth rate between stem elongation and anthesis increased after the early 1980s.
- Association Radiation-use efficiency increased after the early 1980s.
- Association Radiation capture did not change alongside crop growth rate.
- Mechanism Stomatal conductance and greener leaves were proposed as candidate traits explaining radiation-use efficiency.
- Association Shoot water-soluble carbohydrate concentration at anthesis increased with cultivar release year by 0.12 ± 0.018% per year.
