Abstract: Aquilaria malaccensis a well known tree species produced a most high valued resin for perfume industries. Availability of genetically diversified plants in a natural population is an inducer of desirable individuals for sustainable management. Due to their genetic structure few individual trees are susceptible to attack by some specific fungi or insects. Hence, a selection of trees was made from even aged (10-15 years) plantations of individual infected trees from different districts of Assam. Among them nine (09) selected genotypes were established at RFRI, Jorhat, Assam as seedling seed orchard (SSO). The present study was conducted with the hormonal treatment of 50ppm to 200ppm as continuous dip and 500ppm to 4000ppm with pulse dip of total six (06) different concentrations with shoot cuttings of different genotypes of established SSO. One clonal hedge garden with eight (08) genotypes planted in field condition. This is the conservation of genetic diversity of the species has been worked out as a most useful sustainable management and a first report of rooting of shoot cuttings for this economically important species.
