From: Discrepancy of flowering time between genetically close sublineages of Aegilops umbellulata Zhuk.
Phenotypic traits different between UmbL1 and UmbL2 lineages in Aegilops umbellulata. (A) Morphological traits measured in this study. (B) The PCA biplot of all 27 traits data in the Ae. umbellulata population shows the factor loading of each variable (gray arrows) and the scores of each accession (points) based on the first (PC1) and second (PC2) components. The raw value of traits from 114 accessions measured in the 2017–2018, 2018–2019, and 2019–2020 seasons were used and implemented by Bayesian linear model to calculate PCs. Blue squares, yellow diamonds, red circles, and gray triangles indicate UmbL1e, UmbL1w, UmbL2, and unknown lineages, respectively. (C) A heatmap with clustering of the Pearson correlation coefficient (r) between first to fourth PCs and phenotypic traits.
