Abstract
Rosa webbiana is an important shrub of cold desert areas. A study was conducted to examine vegetative propagation of this species through root cuttings. The cuttings were collected from Pooh area of Kinnaur district of Himachal Pradesh during rainy season and immediately brought to HFRI Shimla. They were grouped into four diameter classes and planted under intermittent mist in sterilized sand. Assessment on sprouting, rooting, root number, root length and number of shoots on the cuttings were conducted after one year of planting whereas survival was recorded after one and half year of planting. The maximum rooting percent (97.50) and survival percent was observed in root cuttings having 8-10 mm thickness. However, number of roots and root length were found to be maximum in highest diameter class (12.14 mm) root cuttings. Overall, the diameter class D3 (8-10 mm) of root cuttings may be recommended for mass propagation of Rosa webbiana in green house during rainy season.
