From: Genome-wide association study reveals the genetic architecture of root hair length in maize
Phenotypic variation of root hair length. a Diagram of B73 (left) and Mo17 (right) root hair length. Bars = 1 mm. b Frequency distributions of root hair length. Classes of trait values are shown on X axis and counts of inbred lines with the phenotypic values for these bins are shown on Y axis. c Boxplot of root hair length distribution in different subpopulations. Kruskal-Wallis test was applied to examine the difference of traits among subpopulations. Different letters indicate significance levels at P ≤ 0.05. No. of inbred lines included in each subpopulation are 117, 30, 22 and 112 for MIXED, NSS, SS and TST, respectively
