Selection of hybrid tea-rose seedlings for cut flower yield

Summary In a three year's trial in the greenhouse, flower yields of seedling Hybrid Tea-roses both on their own roots and on a rootstock were recorded. Seedlings on their own roots yield similarly to plants on a rootstock. Highly significant correlations were found annually between the two categories. A selection method for potential yield on the basis of the first year's yield of seedlings on their own roots, is described. Particularly in combination with selection for flower quality this method saves time, labour and space.
