“…The rootstocks PK SK 1 and PK SK 2 are the result of joint selection of the FSBSI NCFSCHVW and the Stavropol Experimental Breeding Station, were distinguished for a number of valuable traits, patented and entered into the State Register of Breeding Achievements of Russia [2]. Rootstock AI 1 is under cultivation.…”

“…The rootstock plays a significant role in the formation of crop yields, it determines the time when the trees enter into fruiting, the general state of plants, and the duration of the garden [1]. In the modern conditions of intensification of fruit production, the need for dwarf rootstocks is increasing, which will provide restrained plant growth, a compact crown of trees, thereby facilitating maintenance and harvesting [2]. The positive aspects of modern clonal rootstocks, in addition to the high productivity of grafted varieties, are genetic homogeneity, resistance to changing abiotic and biotic stressors of the environment, good fixation in the soil and almost complete absence of root growth, compatibility with varieties, easy propagation by vegetative methods [3].…”

The usage of the method of clonal micropropagation of plants is currently the most promising for obtaining virus-free plant material, including clonal rootstocks of stone fruit cultures. The introduction of clonal rootstocks of stone fruit cultures PK SK1, PK SK 2, AI 1 into invitro culture is best doneduring the active shoot growth period in the second decadeof May. During this period, the highest level of explants regeneration was noted: in the rootstock PK SK 1 – 94,6 %, in the rootstock AI 1 78.2%, in PK SK 2 80.4%, in Gisela 5 (control) 85,7%. From the third decade of May, the survival rate of explants begins to decline. At the stage of multiplication on the Murashige-Skoog medium, with the addition of 6-BAP 1 mg/L, the average multiplication factor of clonal rootstocks to the fourth passage was 1: 12 for PK SK1, for Gisela 5 and for AI 11: 8.

Background The 'Colt' is a triploid hybrid of P. avium and P. pseudocerasusL. grown as a cherry rootstock because of its resistance to cherry stem pitting (a debilitating virus disease), Phytophthora root rot, bacterial canker, and gopher damage. ResultsThe current study was carried out using two types of explants: forced (F1) and unforced (F2) and five types of sterilants were used to sterilize explants: 10% sodium hypochlorite (NaOCl) for 10 minutes (S1), 0.1% mercuric chloride (HgCl2) for 5 minutes (S2), ethyl alcohol for 10 seconds (S3), (S1) + (S3) & (S2) + (S3) for sterilization. During culture establishment, six growth regulator regimes viz., BA (Benzyl adenine) (0.20), (0.40) & (0.60) and BA+IBA (Indole-3-butyric acid) (0.20+0.01), (0.40+0.01), and (0.60+0.01) mg/l, two media i.e., MS (Murashige and Skoog, 1962)& WPM (Woody Plant Medium)& two types of explants viz., forced (F1) & unforced shoot tips(F2) were utilized. During shoot proliferation, MS & WPM culture medium with growth regulators viz., BA (0.20), (0.40) & (0.60), BA+IBA (0.20+0.01), (0.40+0.01) and (0.60+0.01) mg/l were used respectively. During rhizogenesis using different media (MS & WPM) with various levels of IBA (0.50), (1.00) (1.50), and (2.00) mg/l, respectively were used. The superior rooted plants were hardened in sand & cocopeat respectively. Conclusion In this experiment, maximum culture asepsis (%) obtained in unforced shoot tips(F2) with (S5),maximum explant survival (%) in forced shoot tips (F1) with (S4), and highest establishment (%) with MS medium, BA (0.6) mg/l & in forced shoot tips (F1). Significantly higher shoot proliferation is obtained with MS medium with BA (0.6) mg/l , maximum shoot number & length in WPM medium with BA (0.2) mg/l. A significantly higher rooting percentage was obtained in MS medium with IBA (1.00) mg/l with maximum ex vitro survival (%) in cocopeat.
