Summary of phenotypes of the parental lines and their F₁ progeny. Suffixes (‘-O’ or ‘-CMS’) are omitted for the names of lines. For cross combinations, see Findings. NK-239mm-O was excluded because no callus was obtained from this line. Each bar represents a single plant; Y-axes are the percentage of explants having each callus phenotype. The five different phenotypes are indicated by bars of different colors: red (Type-A), yellow (Type-B), green (Type-C), blue (Type-D), and purple (Type-E). Types A and B can regenerate plants. Note that only five plants were examined for NK-195mm-O because the frequency of callus formation in NK-195mm-O was very low (see Table 1)
