P-88 ‘Tankeumchu’: A mid-ripening, black-fruited table grape Jungho Noh National Institute of Horticultural & Herbal Science, Korea neongho89@korea.kr ‘Tankeumchu’ (Vitis sp. X Vitis vinifera) is a new table grape cultivar that is diploid, ripens midseason and black-fruited with large clusters (Fig. 1). It has a mean bud burst on Apr. 24, full blooming on June 1, and fruit maturity on Sep. 10. It has an excellent taste with abundant juice and soft firmness. The berry’s mean weight is 7.0 g, and mean content of soluble solids 18.0 o Brix. ‘Tankeumchu’ is more suitable to the mild climate with its moderate resistance to cold hardiness. 169 
P-89 The usefulness of allotetraploidy and isolated embryo culture in vitro for obtaining intergeneric hybrids of grape A. Kataenko*, V.A. Volynkin, V.A. Zlenko, A.A. Poluliakh, N.P. Oleinikov, V.V. Lichovskoi National Institute for Vine and Wine “Magarach”, Ukrainian Academy of Agricultural Sciences, Yalta, Crimea, Ukraine *Corresponding author: volynkin@ukr.net The development of intergeneric hybrids of grape within the Vitaceae family was attempted by using allotetraploidy combined with isolated embryo culture in vitro. Plants of the genus Vitis (eight V. vinifera cultivars, 2n = 38) were crossed with those of the genera Ampelopsis (A. acontifolia, A. cordata, 2n = 40) and Parthenocissus (P. inserta and P. guinguefolia, 2n = 40). To obtain tetraploid forms, buds broken from dormancy were treated with colchicine at 0.5%. The presence of pairs of chromosomes is a necessary prerequisite for synapsis during meiosis and for gamete formation, which is required for fertility in hybrid seedlings. Plants were grown in vitro from embryos isolated from the green berries 40 days after the fertilization. The crossings yielded only two seedlings of ‘Kharty pro Livie’ x Ampelopsis cordata and 11 seedlings of ‘Picpoule noir’ x Ampelopsis acontifolia, because the development of intergeneric hybrids is associated with considerable difficulties due to genetic and biochemical incompatibility of different genera within Vitaceae, which in the first case may lead to genetically unstable plants. The dissection pattern of the leaf in the progeny was different from that of the V. vinifera cultivars used as the female parents (flowers with female flower parts) which had undissected leaves. This suggests quite reliably that this character was inherited from the male parents and the plants obtained are intergeneric hybrids of grape. The possibility of obtaining such forms artificially indicates that they might have arisen from distant crosses in nature in the course of natural evolution. 170
