2014

The untamed roses (Rosa moschata, R. cathayensis) growing in the Himalayan region of the country are unutilized and disappearing very fast due to various factors and need to be evaluated and conserved as important germplasm. Some distinct strains are expected from the natural population which may have potential to be utilized in the improvement of roses. Collection of distinct wild strains of roses was done for their domestication, evaluation, conservation and utilization on the basis of morphological characteristics, viz. colour, shape and size of the opening buds, flower type, i.e. single or double, size and vigour of the plants. Twenty one strains responded to the domestication process and were further evaluated for various traits. Significant variations were observed among the collected species and their strains for the evaluation parameters studied. Only four elite strains IHBT-WR-24, IHBT-WR-16, IHBT-WR-23 and IHBT-WR-21 belonging to four different species with desirable traits, viz. winter active growth, compatibility and flower production potential were identified in the present study as suitable wild rose germplasm. These strains were registered with Plant Germplasm Registration Committee, National Bureau of Plant Genetic Resources, New Delhi.
