Figure 3. Line graphs representing the comparison of observed (solid lines) genetic variances and predicted (dotted lines) genetic variances using the estimated genetic covariance parameters for plant height, ear height, grain yield, grain moisture, days to mid pollen (pollen date measured in days after planting [DAP]) and days to midsilk (silk date, measured in DAP) versus generation of inbreeding. Generations: TC1, topcrosses of S1 lines; TC5, topcrosses of S5 generation. S1, S3, and S5 are the inbred generations per se. Standard error bars represent one standard deviation.
