Trait correlations changed from parental to progeny populations.As an example，Fig.7 shows distribution of correlations between two quality traits and yield.In the training population，the correlation was-0.02 between MR and yield，and-0.68 between EXT and yield（Table 2）.However，the correlations ranged from-0.61 to 0.63 for MR（Fig.7-A）with a mean of-0.008，and from-0.88 to 0.27 for EXT（Fig.7-B）with a mean of-0.51.Thus，even though a quality trait showed a strong negative correlation with yield in training population，it was still possible to see a positive correlation in the progeny population derived from two parents selected from the training population.
