Rosa (Rosaceae) is one of the most economically important genus of ornamental, aromatic and medicinal plants with about 200 species and 20,000 cultivars widely distributed all over the world. Roses are cultivated for ornamental purposes, perfumery industries and medical properties. They are used as garden plants, cut flowers or indoor plants.  Most garden roses are hybrids grafted on to a hardy rootstocks. Rootstock can influence the scion in terms of growth and development in various aspects most important are adaption in pH values, drainage condition of the soil, climatic factors, disease resistance, plant longevity, compatibility, productivity and flower quality. Generally in Kosovo roses propagation by grafting with buds, during a year produced about 80-100 thousand seedlings. The goal of this research was to study level of computability for some Hybrid Tea Roses and Climbing, a same rootstock of  Rosa canina. 'Laxa', which has a wide use in our country.ListenRead phonetical Dictionary - View detailed dictionary In this study are included seven cultivars shrubs and climbing roses such as: Princess de Monaco, Summer Sunshine, Red Lady, Mister Lincoln, Maria Callas, Ena  Harkness and Iceberg.  Propagation of grafting was conducted in August, in the form T-budding, on a same rootstock of Rosa canina 'Laxa'. The experiment was conducted during 2009-2010, tested in a commercial farm in Prishtina, Kosovo. During the vegetation are measured these parameters: number and diameter of roots, length of flower stems, diameter of structural shoots, number of flowers, etc. There was found a significant level of compatibility between rootstock with all tested varieties. This confirms the ability of using this rootstock in large scale commercial rose production in Kosovo climatic and soil condition. Significant mutual effect were also founded between the rootstock and the commercial varieties according to the length and diameter of the flowering shoots, flower diameter  and the dray matter of both rootstock and scion part.
