Performance of Various Apple Clonal Rootstocks under Temperate
Environment using Different Rooting Media and Propagation
Techniques

The present study was conducted at the experimental field of Division of Fruit Science, SKUAST-Kashmir, Srinagar  on one year old rootstock of various types  viz.,  M9-T337 (S1), M-27(S2), MM-106(S3), P-22(S4),  MM-111(S5) by applying ten hilling materials viz., Vermiculite (T1), Saw dust (T2), FYM (T3),Vermicompost (T4), Vermiculite + Saw dust + Pseudomonas (T5),  + Saw dust + Azotobacter (T6), FYM + Vermicompost + Pseudomonas (T7), FYM + Vermicompost+ Azotobacter (T8), Pseudomonas+ Azotobacter+ Soil (T9), Control(T10) (only soil was used as a hilling material) and two propagation techniques viz.,  mound and trench layering. During this study maximum root length (12.90 cm), root number (7.50), root initiation points (4.71), root fresh weight (8.05) and root dry weight (5.93 g) were recorded with saw dust (T₂) hilling material. Moreover, propagation technique P₂ (trench layering) showed significant effect over P₁ (mound layering) in terms of root length, root number per layer and root initiation points. Therefore, above findings will play an important role in augmenting the quality planting production through various multiplication techniques.
