title: Multivariate statistical analysis of yield, its components and characters above the flag leaf node in spring rye.
abstract: The relationships between yield and its components and structures above the flag leaf node were studied in an 8 X 8 diallel of spring rye (Secale cereale L.) by the use of multivariate statistical procedures. Stepwise multiple regression analysis showed that flag leaf characters did not account for significant amounts of variability in yield or its components. Principal component analysis showed no association between yield (and its components) and flag leaf characters while the canonical correlation between the two sets of characters was significant.
