FIGURE 2.

Characteristics of the 19 regenerated plants. (A) Origins and ratios of the alleles in 19 plant genomes regenerated from the calli of WK21/Nip F₁ hybrids. The origins of the alleles are indicated by blue (N) for homozygous allele of Oryza sativa (Nip), pink (W) for homozygous allele of O. glaberrima (WK21), and yellow (Het) for the heterozygous allele. The allelic ratio was calculated with 22 markers used for genotyping (one or two selected from each of 12 chromosomes) detailed in Supplementary Figure 1 and Supplementary Table 2. The state of the leaf surface [rough (R) or smooth (S)] and the presence (yes) or absence (no) of awns (Figure 1A) are also indicated. (B) Leaf surfaces of Nip, WK21, and WK21/Nip F₁ plants. Surfaces of adaxial sides of Nip and F₁ leaves were rough because trichomes were present (black arrows), whereas those of WK21 were smooth because trichomes were lacking.
