Graphical genotype and QTL effect. (A) Graphical genotype of the B73 × Gaspé Flint introgression library (IL). IL lines are represented horizontally and chromosome positions (polymorphic SSR markers as reported in Figure 2) are indicated vertically. Red and green rectangles indicate homozygous and heterozygous Gaspé Flint introgression, respectively. (B) Phenotypic differences between IL lines and B73, represented as horizontal columns. Black columns indicate IL lines significantly different from B73 (P < 0.05). Units are 'no. of days from planting' for days to pollen shed (DPS), 'cm' for internode length (INDL), 'node number' (ND), 'node number' below the top ear (NDBE), 'node number' above the top ear (NDAE) and 'cm' for plant height (PH).
