The present study was conducted to examine the effect of wild apricot seedling rootstock on graft compatibility and growth characteristics of peach, nectarine, apricot and plum varieties. Stratified seedlings of wild apricot were raised in the nursery at a spacing of 15 x 10 cm apart. Prunus scion cultivars of peach (Redheaven, July Elberta and Red Globe), nectarine (Snow Queen, Red Gold and Silver King), plum (Santarosa, Frontier, and Red Beaut) and apricot (Halman, Kaisha and CITH Apricot-1) were tongue grafted on wild apricot seedling rootstock in the second fortnight of February. Maximum graft success was observed in apricot scion (96.30 %) followed by peach scion (87.96 %) and nectarine scion (82.97 %) with minimum stock/scion ratio was also observed with peach scion (1.08). Apricot scion (1.96 m) measured maximum plant height closely followed by nectarine scion (1.88 m)whereas maximum trunk girth was recorded in peach scion (41.13 mm) followed by apricot scion (39.58 mm).Maximum chlorophyll content was recorded in plum scion (29.36 mg/g) varieties followed by nectarine scion (26.58 mg/g) and peach scion (26.45 mg/g). Contrary to higher vigour recorded in apricot scions as compared to other scions of Prunus sp. maximum leaf area was recorded in nectarines followed by peach scion varieties. Comparative studies indicates that plant height, trunk girth, internodal length, leaf area, chlorophyll content and pruning weight differs in different Prunus scions varieties. With the present study, it is clear that apart from apricot varieties peach and nectarine varieties also perform well as compared to plum varieties when grafted on wild apricot seedlings.
