The article presents the estimation of economic and biological characteristics of indeterminant tomato hyb­ rids (Raisa F1, Macarena F1, Emotion F1, Anabel F1, Mariachi F1) under conditions of winter hydroponic. The earliest emergence of fruits is established for Macarena F1 tomato hydrid. The total number of brushes, flo­ ers and w fruits formed on the plant during the vegetation period, is determined. The degree of fruit inception, yield per plant and average weight of the plant are measured. The monthly dynamics of hybrid tomato crops is presented. The largest harvest was collected through May to July. Marketable and non-marketable portions of the harvest and commercial quality of tomato fruits are determined. A close correlation between fruit weight and fruit yield is established. The Macarena F1 hybrid is distinguished as the most precocious and high-yielding variety.

In the article the authors show outcome of three years observation of blackcurrant varieties bred by Study Horticulture Department NULES of Ukraine for their suitabi­ lity to machine harvesting. Blackcurrant is the most common berry crop in Ukraine. When establishing intensive industrial plantations the varieties suitable for machine harvesting should be used. During 2006-2008 limited and unlimited traits of varieties bred by NULES of Ukraine suitability to combine harvesting were studied. All parameters of the examined varieties were compared against the requirements of the «ideal variety”. Simultaneous ripening of berries was observed in varieties Dochka Vorskly – 93,6%, Hovtva, Pamyaty Leonida Myhalevskoho – 92,6%. The pick off effort required to collect berries out of their clusters for all varieties but Yarynka was within acceptable range of 67...129 g. By effort applied for berries crush only Yarynka has failed to meet the necessary requirements. All the varie­ ties but Yarynka have been found suitable by growth habit of their bush (upright and semi-spread). Insufficient number fruits (6-7 pc.) in clusters for varieties Narodna and Yarynka was noted. Berries weight for all studied varieties ranged within 1.27-1.84 g, their drop-off was 3-8%, duration of harvesting period ranged from 8 to 10 days, so all the parameters of varieties suggested they were suitable for picking berries by berry harvesters. Varieties Dochka Vorskly, Universitetska, Hovtva, Pamyatna, Premiera, Narodna, Leleka and Pamyaty Leonida Myhalevskoho were selected as suitable for combine harvesting by the complex of positive parameters.

In the article the authors present the results of the study biometric and qualitative characteristics of berries highbush blueberry varieties (Vaccinium corymbosum L.) in a specific soil and climatic conditions Forest-steppe of Ukraine (Kiev). Investigations were carried out on 11 varieties of American highbush blueberry. Phenological observations, biometric surveys, tasting score and biochemical analysis of the berries have been conducted during the growing season. By results of researches the group of early-ripening varieties includes Bluestar, Earliblue, Patriot, the middle-ripening – Jonne, Atlantis, Bluegold, Bluecrop, Chyk and late-ripening varieties – Amanda, Darrow, Toro. Duration of collecting period of ripe berries was lower (16 days) in varieties Bluestar, Earliblue, Jonne and Darrow. Berries were large sizes in the varieties of Darrow, Amanda, Jonne, in other varieties berries were medium size. By tasting score the berry of varieties Toro, Earliblue, Jonne and Darrow were the best. For biochemical parameters the better varieties were Amanda, Jonne and Earliblue.

In the component composition of volatile solutions determining fragrance of the flowers in apricot and cherry-plum varieties and Prunus brigantiaca Vill. x Armeniaca vulgaris Lam. hybrids there are 36 highest hydrocarbons and benzaldehyde that prevail. There are fewer amounts of the solutions which scare bees (benzaldehyde) in the fragrance of cherry-plum varieties as compared to the flowers of apricot and hybrids. At the same time, the content of tricosane, pentacosane, docosane, heneycosane, eicosane, nonadecan that probably attract bees is higher in the cherry-plum flowers than in the fragrance of apricot and hybrid flowers. The average three years yield of cherry-plum plants (Nikitska Zhovta 10,7 and Salgirskaya Rumjanaya 28,5 t/ ha) is higher than for apricot (Recolte de Schatene 0,3; Rodnik 2,9; Ananasniy Tsurupinsky 7,4 t/ha) and hybrids (8110 – 5,2; 8098 – 6,4 t/ha) that could be explained with better pollination of flowers and better fruit formation. Prevailing components of flower aroma of these plants and their possible link with yield of the objects in questions have been analyzed.

The article highlights key issues of the development of collection of varieties displaying example characteristics of sorghum bicolor and rye. It displays their applicability and value. In order to develop the varietal collections of rye and sorghum bicolor as a methodical tool of varietal examination on distinctness, uniformity and stability, a scrutiny has been given to the morphologic description, morphologic description of plant varieties systematization, as well as field examinations on the facilities of the Poltava and Zhitomir state centers for variety testing. The work undertaken has resulted into the establishment of common knowledge rye, sorghum bicolor varieties collections encompassing 330 and 30 varieties, respectively. A morphologic analyzes of common knowledge varieties enabled to single varieties displaying example characters out of the majority of grades of identification characteristics expression. In particular, for sorghum bicolor of 199 grades as set by the Text Guidelines, varieties with example characteristics were selected for 135 grades by 40 identification characters, while in rye for 81grades out of 99 grades existing by 19 identification characteristics. For each crop Lists of varieties displaying example characters were created, with example referencing to characteristic number and state of its expression indicated, namely of 16 sorghum bicolor varieties and 18 varieties of the rye. The common knowledge variety collections established could be considered as a tool for identifying local differences, i.e. in the scale of Ukraine partially embracing CIS and Europe.

Наведено результати досліджень сприйнятливості колекційних зразків цибулі ріпчастої різного еколого-географічного походження до збудника пероноспорозу (Peronospora destructor Berk). Встановлено, що сорти та гібриди цибулі ріпчастої першого та другого року життя уражуються пероноспорозом. Ступінь розвитку хвороби залежав від інфекційного навантаження, вологості та температури повітря. Дослідження показали, що в середньому за три роки у колекційному розсаднику цибулі першого року життя поширення хвороби припадало на кінець вегетації залежно від зразка і становило 12,7–79,0%, а її розвиток сягав 8,0–61,7%. На насінниках (фаза зав’язування насіння) пероноспороз поширювався у межах 32,7–95,7%, а його розвиток на природно-провокаційному фоні становив 25,7–88,3%. Серед великої кількості вивчених зразків імунних проти хвороби не виявлено. Виділено форми, яким властива відносна польова стійкість проти хвороби, і які будуть використані в селекційних програмах створення нових сортів і гібридів.
