35.1 Seedling phenotype of segregating white Albina (A, alb-d.15) and yellow Xantha (B, xan-g.65) mutants. Homozygous Albina and Xantha mutants are white and yellow, respectively. 35.2 Examples of barley mutants with a light green color due to a low but visible amount of chlorophyll. A. Segregating Viridis mutants (vir-s.44). The light green homozygous vir-s.44 seedlings are not able to set seeds since Viridis mutations are lethal in contrast to vital Chlorina mutations. B. A mutant seedling of Chlorina seedling 12 (fch12.b) surrounded by darker green wild-type seedlings. C. Mutant fch12.b is also possible to distinguish from wild-type plants at later stages of development, which is often more complicated with other light green chlorophyll mutants
