The inheritance of and interrelationships among six quality characteristics and yield were studied in 50 random lines of a wheat cross grown in Alberta. The heritabilities of all quality traits were higher than for yield with the exception of dough development time, which was characterized by a very high genotype ✕ year interaction variance. Seven of the 21 possible phenotypic correlations were significantly different from zero. Of these, the correlations between nitrogen content and yield, nitrogen content and starch damage, starch damage and yield, sedimentation value and dough development time, and between dough development time and tolerance index would be detrimental to a breeding program, while the correlations between thousand kernel weight and yield and between sedimentation value and tolerance index would be advantageous. The genotypic correlations agreed closely with the phenotypic correlations.
