Figure 3.
Genotypic variation in root architectural plasticity traits in the Aus 276 population (A) and the Kali Aus population (B). The plasticity traits shown are those related to grain yield stability in multiple linear regressions for each root experiment. The grain yield stability coefficient was determined by an AMMI-1 analysis, where values close to zero indicate more stable grain yield across field experiments. Genotypes are listed in order of yield stability coefficient, and black symbols indicate lines with the most stable grain yield. Selected genotypes IR 94226-B-265 and IR 94226-B-419 in the Aus 276 population and IR 92801-504-B and IR 92801-527-B in the Kali Aus population are indicated by the lines shown.
