Abstract

The article outlines the ways for the development of horticulture in the Republic of Kazakhstan, provides data on the study of apple, pear, cherry and plum rootstocks. The results of many years of research in order to optimize scion-rootstock combinations suitable for setting up intensive plantings are analyzed. The original plants isolated as a result of such observations should be propagated without disturbing productivity and genetic stability, and mother planting and field repositories should be established with the resulting planting material of the highest quality categories. To obtain basic seedlings, it is necessary, first of all, to use seedlings of the Sievers apple tree (Malus siversi) and the Niedzwetzky apple tree (Malus niedzwetzkyana), growing in the forests of the northern Tien Shan, and for the pear, seedlings of low-growing rootstocks of the East Asian group: Xiang Li, Tszy Li, Yue li, Bai li, Chang bai li, because the seeds of pome crops are free from harmful viruses. Before harvesting stone fruit seeds, it is necessary to test trees, since a harmful viral infection is transmitted with pollen.
