In: Fayoum Journal of Agricultural Research and Development 2015.v. 29(1)Summary: This study was carried out during 2012 and 2013 seasons on "Le-Conte" pear trees budded on four rootstocks namely, "Winter Nelis", "Pyrus betulaefolia",pyrus calleryana" and "Pyrus communis", planted at ElKanater Horticultural Research Station, Kalubeia governorate, Egyp. This study was planned to evaluate the effect of these rootstocks on some horticultural characters as well as resistance the fire blight disease of "Le-Conte" cultivar. Trunk and shoot parameters of "Le-Conte" trees were lower on "P. communis" and "Winter Nelis" rootstocks than those on "P. betulaefolia" and "P. calleryana". Average numbers of spurs and average number of flowers/spurs or/shoot were high on "P. betulaefolia", moderate on "P. communis" and "P. calleryana" but low on "Winter Nelis". Full Blooming date was early on "P. betulaefolia" and "P. calleryana" (9-12 of March) which reflected on the production but late on "P. communis" and "Winter Nelis" (14-16 of March). Results cleared that, "P. betulaefolia" and "P. communis" rootstocks were more productive for• "Le-Conte" cultivar than "P. calleryana" and "Winter Nelis". With respect of chemical fruit characters, TSS and TSS/acid ratio were high and acidity was low on "P. communis" and 'Winter Nelis", on the other hand, TSS and TSS/acid ratio were low and acidity was high on "P. calleryana" and "P. betulaefolia.
