| ABSTRACT A study was conducted during the spring season of 2009, at Azmar mountain, Sulaimani city, Kurdistan Region-Iraq. The commercial cultivar of loquat was used as scion and wild pear trees of 25-30 years old, grown naturally in the region were used as rootstock. The treatments consisted of two budding methods (T-budding and pipe-budding) performed during three dates (mid May, early June and mid June). The experiment was laid out in a factorial randomized complete block design with three replications and twenty buds per replication. Least significant difference (LSD, P≤0.05) was used for mean separation. The percentages of bud-take successes were recorded after two months of the budding operations, whereas the observations on different growth parameters were recorded at the end of the season. Significant influence of the interaction of budding method and budding time on budding success percentage and subsequent growth characteristics of loquat budded on wild pear rootstock were observed. The maximum value of the percentages of budding success (68.20%) was recorded when pipe-budding was done on mid-May, followed by pipe-budding on early-June (65%) and then pipe-budding on mid-June (55.00%). Budding time-method interaction also resulted in the occurrence of significant differences in the length of budshoots, and the number of leaves per budshoot. Pipe-budding performed on mid-May gave higher values of budshoot length and the number of leaves per budshoot (8.6 cm, and 7.03), respectively. No significant differences were observed in budshoot diameter due to budding time-method interaction. These results confirm that wild pears can be used as a good rootstock for loquat production either as a drought resistant rootstock under rainfed condition which means entirely depending on rainfall, thus harvesting of about 7000m3 / ha/ year or as dwarfing rootstock for high density plantation systems in the plains such as Shahrazoor, Kalar, Kifri and Kirkuk, this will be a substantial challenge against ongoing drought years toward the region.
