Seedlings of . . . R. rugosa were treated at the cotyledon stage with colchicine at 0.2% concentration. A drop of this solution was placed between the cotyledons on the growing tip or apex. . . . After two years the tetraploid plants flowered for the first time, the flowers were of a larger size but the colour was the same as the diploid species. The pollen of these flowers was carefully collected and flowers of existing varieties and unnamed seedlings were pollinated with it. . . .These F2 plants were notably fertile and were reciprocally crossed with existing bedding roses. The subsequent years selections of these seedlings were crossed over and over with the existing assortment. . . . [and] we continued with the resistant ones. After 10 years some selections were ready to be sent to the rose trials for evaluation. In 1990 the varieties 'Ville du Roeulx' and 'Melrose' performed very well in the rose trials of Paris (Bagatelle), Geneva, Dublin, Genova (Italy) and Kortrijk and Le Roeulx in Belgium.
