Abstract excerpt
Increasing the water use efficiency (WUE) of our major crop species is an important target of agricultural research. Rice is a major water consumer in agriculture and it is also an attractive genetic model. We evaluated leaf-level WUE in young rice seedlings using carbon isotope discrimination (Delta(13)C) as an indicator of the trait. A survey of Delta(13)C was undertaken in 116 diverse germplasm accessions...
