Fig. 2From: Genome-wide association study and transcriptome analysis reveal key genes affecting root growth dynamics in rapeseedPrincipal component analysis (PCA) of captured traits at five stages in association population. Three obvious groups are indicated with blue circles. PRL trait was clustered into group 1. Other traits captured at 13 DAS and 10 DAT were clustered into group 3. The traits captured at 3 EL, 5 EL, and 7 EL were clustered into group 2Back to article page
