Abstract

The effects of two generations of divergent selection for stolon diameter and stolon amount on the pattern of phenotypic correlations between important agronomic traits in white clover (Trifolium repens L.) were studied. The effects of selection were: the proportions of the variances of traits under direct selection were considerably lower within selection lines than overall and this was associated with a loss of correlation between traits. Unselected traits showed higher proportions of variances remaining within the selection lines and shifts from non-significant to significant correlations from the plants overall to selection lines. The significance of these results and their relevance to strategies of germplasm improvement is discussed.
