3.1 Grain yield
In experiment 1, across genotypes, the average grain yield reduction for
WL1, WL2, WL3 and WL4 was 35%, 46%, 52% and 70%, respectively (Fig.
2a). Yield loss in the waterlogging-susceptible variety Franklin was
47% in WL2; this genotype died completely in WL3. Yield loss in the
waterlogging tolerant genotype (Macquarie+) was 17% and 21% in WL1 and
WL3, respectively, which was lower than other genotypes. In experiment
2, the average grain yield reduction for WL2 was 25-59% (Fig. 2b).
Franklin and Planet showed the greatest yield reduction, while TAMF169
and Macquarie+ were the least reduced by waterlogging. Yield loss in
Macquarie+ was 17-21% in comparison with 43-52% in Macquarie under
continuous one or two-month waterlogging conditions in experiment 1, and
was 18% (Macquarie+) vs 38% (Macquarie) in experiment 2.
