Figure 2. Relationship between midparent grain yield (Mg ha–1) for sister-line inbred line pairs and hybrid grain yield (Mg ha–1) observed in the sister-line hybrids, involving sister lines from three families: {diamond} Family 3920 lines; {blacksquare} Family 3790 lines; {blacktriangleup} Family 3929 lines. Grain yields were averaged across five environments.
