a R indicates the R. reniformis resistant cotton cultivar DP 2143NR B3XF was grown, S indicates the susceptible cotton cultivar DP 2044 B3XF was grown, and F indicates weed-free fallow. The crop in the first year is the first letter followed by 1, the second year is the second letter followed by 2, and third year is the third letter followed by 3.
