520			_aRandom F1-derived progeny from a multiple convergent cross of 16 high-yielding bread wheats were grown in F3 generation, along with the parents, as spaced plants in a glasshouse under optimal conditions. Progeny lines were then advanced without selection to F7 when 58 random lines were sown with the parents in a replicated yield experiment. There were significant genotypic effects for all quality traits in each generation. Phenotypic correlations in F3 and in F7 showed positive correlations between protein content and sodium dodecyl sulfate sedimentation volume (SDS) and Pelshenke wheatmeal fermentation time (PEL), and in F7 a strong negative correlation between grain yield and grain quality (grain protein content (GP), flour protein content (FP), SDS, PEL). Across generations (F3 versus F7), the relationship was strong for particle size index (PSI), moderate for SDS and PEL, but non-significant for the other traits. The results showed that in wheat early generation selection for PSI, SDS and PEL, even when practised upon glasshouse-grown plants, gives useful progress without prejudicing grain yield
