Hybrid index assuming that the pYK* (at the highest altitude) and ab1 (at the lowest altitude) populations are parental populations. (a) Hybrid index of each population, where hybrid index 0 = R. grayanus and 1 = R. palmatus. (b) Interspecific heterozygosity vs hybrid index based on SNPs of 17 nuclear genes. Colored dots indicate broadly defined hybrid classes [63]; BCG as backcrosses with R. grayanus; BCP as backcrosses with R. palmatus; FN as advanced-generation hybrids.
