Field performance of transgenic hybrids overexpressing ZmLOX6 under the control of the pZmPEPC promoter as compared to their nontransgenic sibs across locations (JH, Johnston, IA; WO, Woodland, CA), years and water stress (Opt, optimal conditions; FS, flowering drought stress) with eight replications of four‐row plots under drought stress and four to six replications under optimal conditions. Events that yielded significantly more grain than the null comparator are labelled with asterisks. Event 34 was excluded from the year 2008 under water stress because of its failure in multiple replications. Null comparator grain yield in 2008 under optimal conditions was 12.7 t.ha‐1 in Johnston, IA, and 13.9 t.ha‐1 in Woodland, CA. Application of drought stress at flowering caused an approximately 25% reduction in grain yield. The labels for optimal and drought stress treatments are colour coded in green and brown fonts respectively.
