Other claims from this paper (10)
- Association Grain yield increased across irrigation treatments by an average genetic gain of 111 kg/ha/year.
- Association Kernel number increased with hybrid release year.
- Association Kernel weight increased with hybrid release year.
- Mechanism Kernel number was the primary driver of yield increase.
- Observation Anthesis to silking interval was shorter by three days in new versus old hybrids.
- Observation Grain protein concentration declined by 1% from 1980 to 2020.
- Observation Starch concentration increased by about 1%.
- Observation Oil concentration remained unchanged.
- Observation Water use efficiency increased by 28% over 40 years.
- Mechanism Authors attribute yield increase to both increased potential and drought tolerance.
