Abstract
The present investigation was targeted to conduct the study of rooting behaviour of different genotypes of Gmelina arborea. Rooting of different genotypes shows the effect of collection time of planting material, type of cuttings and also the effect of growth regulatory substance. Nodal sprouting in different genotypes was very good and healthy in all most all type of cuttings. In branch cuttings rooting observed in IBA200ppm and followed by NAA200ppm. In green cuttings NAA100 and 200ppm shows rooting.
