This study was carried out between 2014 and 2015 to determine the effects of varieties and rootstocks with different characteristics in the production of pear nursery on seedling development. Deveci and Santa Maria pear varieties, and Quince C, Fox 9, OHxF 40, Fox 11, OHxF87, OHxF97, OHxF69, OHxF 333 and BA 29 rootstocks were used in this study. Two pear varieties and nine different pear rootstocks were budded by T bud method in 10 September 2014.After 18 months from the budding, rootstock diameter (mm), seedling diameter (mm), seedling length (cm), shoot number (number), average shoot length (cm), average shoot diameter (mm) and rootstock’s offshoot were investigated. The shortest seedlings were obtained from the Fox 11 (104.01 cm) and Deveci (126.83 cm). The smallest rootstock diameter was found as Fox 9 (15.54 mm) and the varieties as Santa Maria (17.83 mm).It has been found that variety x rootstock interaction is effective on seedling diameter and number of shoots. And Santa Maria/Fox 11 were obtained with a minimum number of seedlings (11.71 mm) and number of shoots (3.28).It is important to determine and evaluate the development vigor of the pear rootstocks used in the study, and it is thought that the study will shed light on the scientific nature of the work to be done thereafter.
