A survey was conducted to evaluate seedling-originated rose apple (Syzygium jambos L.) genotypes collected from 3 districts representing the Eastern Dry and Hilly agro-climatic zones of Karnataka. Based on growth, yield and fruit quality attributes, five elite genotypes BRDKRA-1, BNYRA-9, BRACRA-1, BRHSRA-1 and CMGRA-6 were identified and selected for vegetative multiplication. These genotypes were subsequently evaluated for their propagation potential through softwood grafting and patch budding. The present investigation was carried out during 2025-26 at the College of Horticulture, Bengaluru, Karnataka. Significant variation was observed among the genotypes for graft success, bud take, sprouting behaviour, survival and vegetative growth parameters. Among the grafted plants, BRDKRA-1 recorded the highest graft success (70.00%) at 60 days after grafting (DAG) and graft survival (62.50%) at 120 DAG. The genotype also exhibited the earliest graft sprouting (18.32 days), highest number of sprouts per graft (3.13 at 30 DAG), maximum number of leaves per sprout (14.25 at 120 DAG) and maximum graft height (19.71 cm). Under patch budding, BNYRA-9 recorded the highest bud take (52.50%) at 60 days after budding (DAB) and bud survival (37.50%) at 120 DAB. The same genotype also produced the highest number of shoots per plant (0.60), maximum sprout length (16.22 cm), maximum leaf length (13.53 cm) and highest graft girth (6.05 mm) during the later stages of growth. Softwood grafting consistently resulted in earlier sprouting, higher success and survival percentages and superior vegetative growth compared with patch budding.
