Fig. 2. Distribution of genotypes assigned to F2 plants from the cross Js-12-LPA/IDO563. F2 plants were classified into five categories: (1) Homozygous wild-type if no progeny (F2:3) kernels were HIP (high inorganic phosphate) and all F2:3 kernels with intermediate Pi concentrations had Pi concentrations below the mid-parent mean; (2) Heterozygous if at least one F2:3 kernel was HIP and at least one F2:3 kernel was wild-type; (3) Heterozygous if HIP kernels were observed, no wild-type F2:3 kernels were observed, and kernels of intermediate Pi concentration had concentrations below the mid-parent mean; (4) Homozygous for the low phytic acid trait if no F2:3 kernels were wild-type and all F2:3 kernels with intermediate Pi concentrations had Pi concentrations above the mid-parent mean; (5) Homozygous for the low phytic acid trait if all F2:3 kernels were HIP.
