Figure 6
Plot of the relationship between mean wilt score of individuals binned by marker number (error bars are 95% confidence intervals), for phenotypic data of three years (minimum of ten individuals per bin). A clear and consistent increase in wilt resistance is seen across all years with increasing marker number. However, the level of wilt resistance observed depends upon the disease pressure for that year. 2009 was the most severe year for disease, followed by 2011 and then 2010. For comparison mean wilt scores of ‘Redgauntlet’ and ‘Hapil’ in 2009 were 3.1 and 8.1, respectively). Linear regression analysis of the relationship was performed and the gradient and intercept are shown for each year.
