The objective of our researches was to get to know the new hybrid elites and also the new pear tree varieties, with regards to their behaviour under the attack of the main diseases (Venturia pirina, Mycosphaerella sentina) and pests (Psylla piri), in the climatic and soil conditions from Lugoj area. Similar researches in pear tree have never been carried out so far in Banat; actually this is the first pear tree collection founded in 1998. A part of the hybrids studied were homologated per periods of research as new pear tree varieties (72-32-62-Virgiliu hibernal; 58-12-55-Milenium). Our researches have supervised two diseases (Venturia pirina and Mycosphaerella sentina) and one pest (Psylla piricola), specific as presence in young pear tree orchards. The practical implications have consisted in the introduction of some new pear tree varieties in the variety range from Banat, namely Euras, Milenium and Virgiliu hibernal.
