Fig. 5From: Identification of genetic loci associated with forage quality in response to water deficit in autotetraploid alfalfa (Medicago sativa L.)Quantile-quantile plots of marker-trait association from GWAS for forage quality traits under well-watered (a), mild (b) and severe (c) water deficits in the alfalfa association panel. The expected (solid lines) against observed (dot lines) -log10 p-values are presented on X-axis and Y-axis, respectively. Each color curve represents a quality trait as showing at the bottom of the figuresBack to article page
