Abstract
The paper presents the results of assessing the compatibility of 22 pear cultivars promising for industrial production with dwarf rootstocks based on common quince of VNIISPK breeding. There was good accretion with the rootstock and full-fledged development of 10 pear cultivars: Yeseninskaya, Tyutchevskaya, Muratovskaya, Pamyati Yakovleva, Bryanskaya Krasavitsa, Belorusskaya Pozdnya, Nika, Lira and Conference, as well as Alaya, an elite form of VNIISPK breeding. 5 pear cultivars had negative affinity: Orlovskaya Krasavitsa, Orlovskaya Letnya Skorospelka from Michurinsk, Rusanovskaya and Tikhiy Don. They require an intermediary with good compatibility with the stock. Satisfactory compatibility was revealed for Ploshanskaya as well as for 7 pear cultivars in the nursery, the consequence of which was good accretion with rootstocks, but weak development of grafts and low yield of seedlings in production (Annushka, Prosto Maria, Pamyatnaya, Chizhevskaya, Krasavitsa Chernenko, Vidnaya).
