Quality control of DNA extracted with SILEX (orange) and SMP kit (blue) in 1380 and 480 tomato samples respectively. Box and whisker plots are based on a A₂₆₀/A₂₈₀ and b A₂₆₀/A₂₃₀. Each dot represents a sample, the median is indicated by a horizontal line, the box represents the upper and lower quartiles and the whiskers show the variability outside the quartiles.”
