摘要

Abstract

To evaluate the effect of genetic improvement of the turbot Scophthalmus maximus

we analyzed morphological differences between a fast-growing strain obtained by family selection and the common cultured strain

by principal component analysis

stepwise discriminant analysis

and t -tests. Although they clearly differed morphologically

plots of the principal components of the two strains partially overlapped. However

the difference between the strains was supported with very high precision by discriminant analysis. The t -tests revealed that 4 of the 13 morphological traits analyzed were highly significantly different (P <0.01)

4 traits also differed significantly (P <0.05)

and the remainder did not differ significantly. The coefficients of difference of the 13 traits were all lower than the threshold value between subspecies (1.28). Together

the results indicate that a trend for segregation of characters from the common cultured strain have already appeared in the selected fast-growing strain but the degree of segregation have not risen to subspecies level.
