Other claims from this paper (8)
- Intervention effect Waterlogging in alkaline soil reduced mean grain yield by up to 70% relative to drainage.
- Intervention effect Waterlogging reduced plant height, tiller number and 1000-grain weight.
- Association At one waterlogged site, tiller number accounted for up to 68% of genetic diversity in predicted yield.
- Association Tiller number correlated positively with predicted yield at the second waterlogged site.
- Observation Soil salinity differed by up to fourfold between waterlogged sites.
- Association Accounting for salinity yielded strong correlation across environments with r2 of 0.73.
- Mechanism The authors propose crown root development as a physiological basis for the tillering-tolerance relationship.
- Recommendation The authors recommend selecting for tiller number to improve wheat under vegetative-stage waterlogging.
