Figure 5. Individual grain weight as a function of time expressed as days after flowering (DAF) for resistant (R) and susceptible (S) isohybrids under V. dahliae natural infections. Differences were statistically significant after 20 DAF (SE = 0.74, 1.26, 2.31, 1.74, and 2.00 mg at 14, 21, 29, 37, and 45 DAF, respectively). Data for isohybrid 2A. Grainfilling rate estimated from 14 to 29 DAF was 1.41 and 1.26 mg d^–1 for R and S cultivars, respectively. Data from Trial 2.
