Chemical characteristics of fruit spirits produced from three black currant cultivars (Malling Juel, Ometa, Ben Sarek) and two red currant cultivars (Rondom and Versailles) grown in Serbia were examined using gas chromatography. In addition, sensory evaluation of the spirit samples was performed using the Buxbaum model of positive rating. Fruit spirits produced from black currant cultivars displayed the highest contents of methanol (267.2 - 595.0 g/hl A. A) and amyl alcohols (74.2 - 204.8 g/hl A. A). Total sensory scores of currant brandies ranged between 17.60 and 18.40, while currant brandy produced from Ben Sarek black currant cultivar received the highest score (18.40). All tested samples of currant brandies fulfilled EU requirements as regards their content of methanol and other components such as acetaldehyde, ethyl acetate and high alcohols. The currant distillates were compared with other commercial spirits, including plum and grape brandies.

The article highlights the results of research carried out in 2019-2020 to study the reasons for the drying out of the stems of black currant (Ribes nigrum L.), red currant (Ribes rubrum L.) and golden currant (Ribes aureum L.). As a result of research, the fungus Sphaeropsis malorum Peck. in the first in Russia it was revealed from the drying stems of three types of black currants, red currants and golden currants. This  pathogen inhabited currant stems together with fungi from the genus Cytospora spp., causative agents of stem drying. On red currants, it was established that S. malorum was the main causative agent of branch drying, as indicated by the high frequency of occurrence (75.0-83.3 %) of this fungus on the affected stems, compared with species from the genus Cytospora spp. (16.7-33.3 %) and Phomopsis ribesia (25.0 %). Due to the fact that the cultivation of currants in the immediate vicinity of apple and pear trees leads to infection of plants with the fungus S. malorum, it is necessary to avoid planting currants in the vicinity of fruit-bearing seed gardens.

One of the prospective ways to safely preserve the genetic resources of red and black currant for breeding needs is the cryopreservation of cuttings with dormant buds. Vegetative cuttings of 12 varieties of red and 11 varieties of black currant were harvested in various regions of Russia: North, Northwest, and Central. Their viability after cryopreservation in nitrogen vapors (about −184 °C) under field conditions was studied. For red currant samples, it ranged from 61.2 ± 1.2% to 72.3 ± 3.0%, black currant—from 58.9 ± 1.1% to 73.5 ± 1.9%. In the group of red currant varieties, there were no significant differences in viability between varieties after cryopreservation. In the group of black currant varieties, “Chereshneva” and “Georgiy” had lower viability after storage in liquid nitrogen vapors than the others, 61.1% and 58.9%, respectively. On red currant, dry growing conditions of the experiment year significantly decreased the viability after cryopreservation. Neither black nor red currants revealed the influence of the place of harvesting on the survival of cuttings after cryopreservation. These results indicate the possibility of using cryopreservation to preserve cuttings of red and black currant with dormant buds collected in regions with different climatic environments.

Artificially inoculated single-leaf cuttings and small plants consistently differentiated european black currant (Ribes nigrum L.) cultivars susceptible to white pine blister rust (WPBR; Cronartium ribicola J.C. Fisch.) from immune cultivars carrying the Cr resistance gene. Black currant cultivars Consort, Crusader, and Titania showed no signs of infection with any of 21 strains of WPBR, suggesting that strains able to overcome immunity conferred by the Cr resistance gene, if they exist, are uncommon in North America. However, in red currant (Ribes rubrum L.), two sources of material presumed to represent the immune cultivar Viking showed no resistance to infection. All rust strains infected and sporulated as if the cultivar were fully susceptible, casting doubt on the true identity of available sources of `Viking'.

During Dec. 1997 and Jan. 1998, the gooseberry mite, Cecidophyopsis grossulariae Collinge, was observed to infest 48 currant and gooseberry (Ribes L.) cultivars in a field plantation in Corvallis, Ore. The mite was observed on 29 black currant, (Ribes nigrum L.), two red currant [Ribes rubrum L. and R. sativum (Rchbch.) Syme], 12 gooseberry [R. uvacrispa L., R. oxyacanthoides var. setosum (Lindley) Sinnot], and three R. ×nidigrolaria Bauer cultivars and the hybrid R. nigrum × R. pauciflorum Turcz. ex Pojark. A range of mite infestation levels was observed, with some cultivars not being infested, some with light infestation, having 1 to 100 adult mites per bud, and some heavily infested, with more than 100 mites per bud. On lightly infested buds, the mites were inside bud and leaf scales; in heavily infested buds, mites were also observed on floral primordia. Scales of infested buds were often loose and appeared more open than noninfested ones. Mite distribution varied by branch within a plant. Black currant cultivars with the heaviest infestation of C. grossulariae were of Scandinavian, Russian, Scottish, and Canadian origin. The Russian black currant cultivar Tunnaja was the most heavily infested with more than 1000 mites per bud. Floral primordia were damaged in heavily infested buds.

The main goal of the scientific institution was and remains to improve the assortment of fruit and berry crops for the development of domestic horticulture. Black currant breeding at VNIISPK was started by A.F Tamarova and continued by the doctor of agricultural Sciences T.P.Ogoltsova and doctor of agricultural Sciences S.D. Knyazev. A long-term breeding program has been developed. The main goals of the program are to create black currant cultivars with continuous resistance to diseases, first of all powdery mildew, as wells resistance to pests, i.e. bud mite. As a result of the long-term work, over 40 black currant cultivars have been developed, 14 of them are zoned. Red currant breeding was led by the candidate of agricultural Sciences L.V. Bayanova; since 2001 the work has been continued by the candidate of agricultural Sciences O.D. Golyaeva. ‘Heinemanns Rote Spӓtlese’, the descendant of R. multiflorum Kit., was involved in the red currant breeding for the first time in Russia. On its genetic basis, a series of late maturing cultivars with long and dense racemes was created. At the Institute, in total 21cultivars of red currants have been developed, 13 of them are zoned. At present, red currant cultivars make up 25.5% of the zoned assortment in Russia. The first research on gooseberries was stated by V.P. Semakin and A.F Tamarova; since 1992 the systematic gooseberry breeding has been carried out by the candidate of agricultural Sciences O.V. Kurashev. On the basis of Grossularia robusta, we have created gooseberry forms that are resistant to powdery mildew and leaf spots. These forms are highly productive, weakly thorned, having bush habit suitable for mechanized harvest. The result of breeding activities was the transfer of 6 gooseberry cultivars to State agricultural testing: ‘Solnechny Zaychik’, ‘Nekrasovsky’, ‘Yupiter’, ‘Zemlianichny’, ‘Moryachok’ and ‘Discovery’.

Kasturi (Mangifera casturi) is a typical plant of South Kalimantan which has only been used for consumption because of its distinctive taste and aroma. Mangifera indica, which is in the same genus as Mangifera casturi, shows antioxidant, antibacterial, antifungal, and antidiarrheal activity, so it is suspected that this plant has the same activity. Crude methanol extract from the meat of Casturi mango was fractionated using n-hexane, ethyl acetate, and methanol-water. Testing for antibacterial activity and minimum inhibitory concentration (MIC) were carried out using the disk diffusion method (Kirby-Bauer). The positive control used was Chloramphenicol because it has an antibacterial range that is rather broad and the negative control used was 10% DMSO. The fraction that had the greatest antibacterial activity was the ethyl acetate fraction; with the formation of a clear zone of 7.98mm against Pseudomonas aeruginosa and 7.52mm against Bacillus cereus, with a minimum inhibitory concentration of 2mg/mL. The next test was a cell leakage analysis which revealed an increase in absorbance at MIC 1 and MIC 2. The Gas Chromatography – Mass Spectrometry (GC-MS) results from the ethyl acetate fraction revealed the presence of phenolic, flavonoid, and glycoide content, with the highest compound concentration of 5-Hydroxymethylfurfural. Keywords: Antibacterial, Extract, Ethyl acetate, fraction, Mangifera casturi Abstrak Kasturi (Mangifera casturi) merupakan tumbuhan khas Kalimantan Selatan yang selama ini hanya dimanfaatkan untuk dikonsumsi karena rasa dan aromanya yang khas. Mangifera indica yang masih satu genus dengan Mangifera casturi menunjukkan aktivitas antioksidan, antibakteri, antijamur, dan antidiare sehingga diduga tanaman ini memiliki aktivitas yang sama. Ekstrak kasar metanol daging buah mangga kasturi difraksinasi dengan menggunakan n-heksan, etil asetat, dan metanol-air. Pengujian aktivitas antibakteri dan kadar hambat minimum dilakukan dengan menggunakan metode difusi cakram (Kirby- Bauer). Kontrol positif yang digunakan adalah Chloramfenikol karena memiliki spektrum antibakteri yang cukup luas dan kontrol negatif yang digunakan adalah DMSO 10%. Fraksi yang memiliki aktivitas antibakteri terbesar pada penelitian ini adalah fraksi etil asetat dengan terbentuknya zona bening sebesar 7,98mm terhadap Pseudomonas aeruginosa dan 7,52mm terhadap Bacillus cereus dengan kadar hambat minimum 2mg/mL. Uji selanjutnya adalah uji kebocoran sel yang menyatakan adanya peningkatan absorbansi pada KHM 1 dan KHM 2. Hasil pemeriksaan Gas Chromatography – Mass Spectrometry (GCMS) dari fraksi etil asetat menyatakan adanya kandungan fenolik, flavonoid, dan glikosida dengan senyawa tertinggi yaitu 5-Hydroxymethylfurfural.
