EVALUATION OF WINTER HARDINESS OF HYBRID PEAR FUND BREEDING OF THE DEPARTMENT LISAVENKO RESEARCH INSTITUTE OF HORTICULTURE FOR SIBERIA OF FEDERAL ALTAI SCIENTIFIC CENTRE OF AGROBIOTECHNOLOGIES

Abstract

The results of studying the winter hardiness of the hybrid pear fund of Lisavenko Research Institute of Horticulture for Siberia are presented. The investigations were carried out in the southern part of Western Siberia, with contrasting weather conditions in the late autumn and winter. The objects of the study were 369 pear seedlings from free pollination and controlled crossing, conducted in 2005-2006. The aim of the research was to identify frost-hardy families among hybrid pear seedlings. The studies were conducted using ordinary methodology, years of research are 2015- 2018. It was found that for further use in breeding two of the most winter-hardy family (Kupava x Lel, Kupava x Karataevskaya), are promising, in which from 70 to 75% of hybrids had no signs of freezing.
