The present investigation was undertaken with an objective to study the effect of rooting media on multiplication of apple clonal rootstock Merton 793 through stool layering at Dr. YSPUHF, Solan (H.P.). The stools were mounded up with eleven different rooting media combinations of soil, sand, cocopeat, vermicompost, forest leaf compost and field soil as control during late June, 2009. The highest percentage of rooted stool shoots (85.41 %), number of rooted stool shoots (7.40/stool), number of adventitious roots per stool shoot (19.33), total root length (6.48 m), stool shoot diameter (12.67 mm), leaf area (11.41 cm2), root to shoot ratio (0.089) and average root diameter (1.78 mm) was observed in the stools mounded up with cocopeat + vermicompost (1:1, v/v). Whereas, the linear growth of stool shoot (130.43 cm), number of leaves per stool shoot (79.16) and total biomass in terms of fresh (115.78 g) and dry weight (62.75 g) were recorded in the stools mounded up with vermicompost + forest leaf compost (1:1, v/v).
