Medlar has a limited distribution in modern orchards. Industrial plantings of medlar in the Russian Federation are absent, among other things, due to low germination of seeds and slow growth of seedlings, which significantly complicates the cultivation of seedlings on seed rootstock. In 2021-2022, studies on the use of quince as a rootstock in the cultivation of German medlar seedlings were conducted at the educational and experimental field of Kabardino-Balkarian State Agrarian University. The results of experiments with inoculation of two varieties of medlar on quince showed that during budding and spring grafting with a cuttings, the survival rate of the inoculation components and further growth of seedlings does not differ from other seed crops, the intensity of growth processes is not inferior to pear trees grafted on quince (the control variant � the pear variety Talgarskaya Krasavitsa � has a high degree of compatibility with quince A). On average, in 2 years for both varieties of medlar, the survival rate of grafting eyes was 90%, and grafted cuttings � 83%. In the control (pear on quince), these indicators were noted at the level of 92.0 and 84.8%, respectively. The height of medlar seedlings (on the stock of Quince A) in autumn was 140 and 133 cm (depending on the grafting options), and for pears grafted on quince A � 152 and 130 cm, respectively. Due to the fact that the difference in survival rate between the studied variants and the control is insignificant, it is proposed to use Quince A as a rootstock when growing seedlings of the German medlar.
