Description
The article gives a brief summary on the results of the introduction of rose varieties of climbing type in the central sub-zone of the Krasnodar region. Starting from the year 2000 in our institute a collection of roses from different garden groups, which includes 164 varieties, has been formed. Presently the rose varieties with long stems (from 2.5 m or more) are popular among specialists of landscape industry and floristlovers. Therefore we carry on introductions and study rose varieties of the groups of Rambler and LargeFlowered Climber. Rose varieties with valuable decorative signs, with enhanceable resistance to cold and drought-resistingness are selected. The valuable varieties and sources of the indicated signs are identified. Varieties of Albertine, American Pillar, Devichiy grezy are the sources of bright flower color; Bobbie James, Dorothy Perkins, Duc de Constantine - sources of long (more than 4 meters) of flexible shoots Warthburg - the source of early flowering. Variety New Daun - one of the few varieties of Rambler, which is characterized by re-bloom throughout the growing season in the conditions of the Krasnodar region. The indicative collection of several rose varieties includes the group of Large-Flowered Climber. A variety called Adzhimushkay is a source of large fragrant flowers of bright and early flowering. For the variety of Crimskiy Motive we noted the presence of a valuable feature - long flowering during the dry season (July-August). Flammentanz was included into the collection as one of the most winter resistant varieties of large-flowered. Promising varieties of the series of Super Rambler in the conditions of Krasnodar in the dry season formed short shoots, and flowers were not formed. Rose varieties included into the collection can be considered indicative of "anchor" genotypes, which are valuable for involvement into the selection process

Description
The article presents brief results of the introduction of Hibiscus syriacus L. varieties for a signs collection in the south of Russia. Since 2007, Federal State Budgetary Scientific Institution North Caucasian Regional Research Institute of Horticulture and Viticulture (Krasnodar) has been working on the introduction and researching of Hibiscus Syriacus varieties and signs collection is being formed. Introduced varieties of hibiscus are obtained in zones with a moderate temperature-humidity regime, therefore not all are easily adapted in the conditions of the south of Russia. According to the results of the research, several varieties of sources of valuable traits have been identified. Varieties with pure white petals: Totus Alba, William R. Smith, White Chiffon, White Pillar. Varieties with bright crimson color petals: Freedom, Carneus Plenus, Woodbridge, Duc de Brabant. The Blue Chiffon variety is the source of bright blue petals, Sanchonyo is a source of bright purple-crimson petals. Of great value are varieties that have an unusual combination in the color of petals, like the varieties Monstrosus and Hamabo. By the sign: a large flower (d of a flower more than 12 cm), the collection includes varieties White Chiffon, Chaina Chiffon, Pink Giant. Variety Dorothi Crane and hybrids: T-16-11, T-7-11, K-16-12 are identified as sources of round, wheel-shaped flower. With a double flower type, the varieties are represented by varieties: Blue Chiffon, White Chiffon, China Chiffon, Leopoldii, Speciosus, Lucci, Sanchonyo, Freedom, Carneus Plenus. Varieties: Woodbrige, Russion Violet, Ledy Stenly, White Chiffon, China Chiffon, Purple Pillar are sources of abundant long (more than 3 months) flowering. With a high degree of self-purification after flowering, varieties are distinguished: White Chiffon, Sanchonyo, Purple Pillar, White Pillar, Freedom. Varieties: China Chiffon, Freedom, Lucii, Leopoldii, RussionViolet, hybrid forms: T-16-11, T-18-11, T-21- 12 are characterized by increased adaptability to abiotic factors in south of Russia. Dedicated varieties and forms - sources of valuable economic and biological characteristics are of interest for involving in selection and allow to model varieties with given properties

Description
The features of seeding and vegetative reproduction of Hibiscus Syrian (Hibiscus syriacus L.) in the South regions of Russia are accounted in the article. It is shown that the not sorted Hibiscuses reproduce better by seeds. Sowing is made before winter (November). The young growth appears on April-May of next year. The seedlings of first-year are wintering badly in the open soil; therefore, it is better to keep them in the basements in sand. When one-year seedlings are planting next spring we receive the standard seedling in the autumn this year. Planting material of high quality of Hibiscus Syrian was grown by means of inoculation and by the grafting method. It is recommended to execute an inoculation in the first tenday period of September. It is possible to execute the reproduction by means of inoculation in case of deficit of shoots of high quality plants and for the rapid fixing of sort. It is preferable to reproduce a Hibiscus Syrian by wood shoots in the frames or by green shoots in the unheated greenhouses in an autumn-winter period. The best results in the carried out research were got at planting shoots for further growth in the containers at the greenhouses with creating of shadow in a summer period. The high speed of shoots growth in the containers of cv. Duc de Brabant, cv. Woodbrige and cv. Russian Violet varieties are observed. The vegetative mass of shoots of cv. Speciosus, cv.Carneus Plenus and cv. Red Heart varieties increases more slowly. A conclusion follows, that the studied crop must take the deserving place in the assortment of decorative bushes of plant nursery farms

Description
An approach to the valuation technique of decorative signs Syrian Hibiscus (Hibiscus syriacus L.) is suggested. A scale consisting of 15 characters is developed. Each attribute in this scale is evaluated and indexed by the coefficient of the importance of this trait afterwards. General guidance of the evaluation of each decorative feature is given
