Abstract
The present investigations entitled “Response of different combination of rootstock and scion
on the success and growth of apple grafts (Malus x domestica Borkh.)” was carried out in Fruit
Nursery, College of Horticulture, VCSG, Uttarakhand University of Horticulture and Forestry,
Bharsar during 2015-2016. In this study, three rootstocks namely M-793, M-7 and MM-111 and
three scion wood viz. Vance Delicious, Gold Spur and Oregan Spur selected and nine
combinations of these rootstock and scion wood were made and grafted with three replications.
The different parameters for this rootstock and scion combinations were recorded to evaluate the
best combination.
The treatment T1 ( M-793 + Vance Delicious) had maximum graft height, number of branches,
number of leaves , rootstock diameter, scion diameter, root length and root diameter (i.e., 92.40,
15.33, 105.07, 10.12 mm, 9.96 mm, 25.27 cm and 12.03 mm respectively). The minimum days
taken to bud sprout (10.58 days), and maximum percent survival (93.33 %) were recorded with
T9 (MM-111 + Oregan Spur). The maximum leaf area (15.58 cm2) was recorded with T6 (MM-
111 + Gold Spur).
Hence, the different combinations of rootstock and scion varied in their growth characteristics.
The treatment T1 (M793 + Vance Delicious) was the best combination of rootstock and scion
where healthy apple plants with good root and shoot growth were observed.
