Effect of Cultivar Selection on Soil Population of <i>Verticillium dahliae</i> and Wilt Development in Cotton

Fig. 3. Effect of pre-plant (April-2010) soil inoculum density of Verticillium dahliae on lint yield for Advanced breeding line (top) and Stoneville 4545B2RF (bottom). Advanced breeding line was partially resistant and Stoneville 4554B2RF was susceptible to V. dahliae. RRR, RRS, RSS, SSS, SSR, and SRR represent three-year rotations where the first letter refers to the cultivar grown in 2008, the second letter to the cultivar grown in 2009, and the third letter to the cultivar grown in 2010.
