Figure 1From: Dissecting grain yield pathways and their interactions with grain dry matter content by a two-step correlation approach with maize seedling transcriptomeSchematic representation of a two-step correlation approach. L, average expression level of a gene in the parents of a hybrid; g*, gene not included in set S in a previous repetition of Step 2; r, correlation coefficient; p, p-value for statistical significance; PY, hybrid performance for grain yield; HY, mid-parent heterosis for grain yield.Back to article page
