From: Dearth of polymorphism associated with a sustained response to selection for flowering time in maize
Response to selection in the F252 and MBS DSEs. The average flowering time of each family as estimated by difference to the first generation per unit of control residual standard deviation is plotted against time in generation. A separate color code for lines and points has been attributed to each family. Vertical lines indicate standard deviation within families. Data from the F252 and MBS DSEs have been treated separately, except for control lines. The shaded area represents the range of flowering time variation in control lines (data available only from generation G3)
