Generation F₀ refers to the progeny of parents that were screened, numbered, and propagated from the pooled, field-collected seed in TA136. Generation F₂ refers to the plants grown from self-seed collected from pedigreed parents in generation F₁. The parent column lists the pedigree no., prefixed with a “TP,” belonging to the individual plant from which the family is descended (see Fig. 3). N represents the no. of individuals comprising each family. A parental response score of (−) indicates that the parent did not form any haustoria in response to induction with 10 μm DMBQ; a (⁺) score indicates that the parent formed at least one haustorium in response to induction with 10 μm DMBQ. Responders and non-responders varied significantly in haustorium development according to a one-way ANOVA at P < 0.001 and Tukey's multiple comparisons test at P ≤ 0.01.
