In this article presented the results of the experiments conducted to determine the optimal period of increasing the level of survive of apricot seedlings in the cultivation of apricot seedlings by the cleft grafting method. In the experiment, the method of grafting the buds of the fruitful local varieties of grafted apricots to the modern weakly growing grafts at different times was tested. In this case, the Mirobolan rootstock was grafted with the Yubileinyi Navoi, Subkhani, Isfarak, Aq kandak, Shalakh and introduced Rubista varieties of apricots. Observations show that the best time for grafting onto Mirobolan cuttings, which reproduces vegetatively, is the first and second ten days of March (01-20/III). The number of dead shoots before the autumn inspection when grafting was done during this period was the least (16.6-23.8%). The highest surviving was also high in Shalakh and Isfarak varieties, respectively, and reached 78.8-863.4%.
