The current article presents the results of the influence of lighting conditions on the morphogenetic potential of Ipomoea batatas (L.) microcuttings in vitro. The studied objects were 4 sweet potato cultivars - Jewel, Purple, Porto Rico, Vinnitsa pink. Microcuttings of I. batatas were cultivated in vitro. We used nutrient medium with mineral salts (according to the prescription of Murashige and Skoog (MS)) and medium only with distilled water (without mineral salts). All nutrient media contained sucrose 2% and agar 0.7%. Hormones were not added to the nutrient media. We studied the influence of the different red (R) and far red (FR) ratios, as well as the red and blue light spectrum on the formation of microshoots and the root system. It was shown that the lighting regimes (R and FR ratio) had a stimulating effect on the roots and shoots growth regardless of the medium composition. Moreover, significant results were obtained under conditions of complete nutrition (mineral salts according to MS) in contrast to the control treatment (fluorescent lamps) and the treatment without salts. The best results were obtained at the R=FR treatment. This light treatment can be recommended for inclusion in the technology of clonal micropropagation of sweet potato. When red and blue spectra were added to normal illumination in different proportions, it did not lead to an increase in the morphogenetic potential of cultivated explants. The growth rate (μ) of the main shoot from axillary buds was about 2 times less than in the control treatment.

The article presents the results of a reconnaissance study of the suitability of sweet potato varieties collection for cultivation and breeding process in the conditions of the Central region of the Non-Chernozem zone. Sweet potato cuttings with 4-5 nodes were planted according to the scheme 70 x 40 cm with subsequent watering. During the growing season, sweet potato was watered as necessary. Each variant was tested in 4-fold repetition, 10 plants per plot. The varieties had a high variability of all economically useful traits within the repetitions. For most varieties, the sum of effective temperatures was not enough to accumulate a sufficient amount of plastic substances in the root tubers. As a result of our research, it was found that sweet potato varieties Vinnitskiy rozoviy and Manchzhurskiy are most suitable for cultivation in the CRNZ. They are characterized by a relatively high yield of commercial root tubers. The remaining varieties (Americanskiy begevy, Boregard, Yaponskiy, Germanskiy belyi and O'Henry) are not suitable for cultivation in this zone. Nevertheless, they are characterized by a high potential for the formation of root bulges, which can be used in sweet potato breeding. The possibility of breeding work with sweet potato in the conditions of the CRNZ is shown. Nevertheless, for successful work in this direction, it is necessary to use a greenhouse.

In vitro propagation of sweet potato (Ipomoea batatas (L.) Lam.)

Abstract: The results of optimizing the conditions for growing sweet potatoes in vitro are presented. It is shown that the mineral composition of the nutrient medium has a significant effect on the growth of side shoots. With the simultaneous formation of shoots, rooting of micro gears was observed.
