Hetero-fertilization frequencies as detected by one or two markers in seven F2 populations.

Note: The pollination model for five F2 populations is A×B, where A is used as female parent and B as male parent. For consistency, the genotypes of SSR allele combination in endosperm (E) and leaf (L) are shown using the same symbol with the pollination model A and B.注：五个F2群体的授粉模型均为A×B，其中A作为母本，B作为父本。为保证一致性，胚乳（E）与叶片（L）的简单重复序列（Simple Sequence Repeats，SSR）等位基因组合的基因型，均采用与授粉模型A、B相同的符号进行标注。
