The work aimed to assess the cultivation and breeding prospects of the new Frontenac Gris technical grape variety obtained in 2003 by clonal selection as a colour-mutant Frontenac red technical grape originated by the University of Minnesota, USA. The variety is a complex cross-species hybrid with early maturity in the zone of Novocherkassk, Rostov Region. The variety was studied in 2018-2020 following the common viticulture and winemaking protocols at an experimental plot of the Novocherkassk trial field of All-Russian Research Institute of Viticulture and Winemaking named after Ya.I. Potapenko — Branch of the Federal Rostov Agricultural Research Centre. Vineyards were uncovered, unirrigated, grafted, Berlandieri×Riparia Kober 5BB rootstock, 3×1.5 m planting scheme. Formation as medium-standard double-shouldered horizontal cordon. By combination of economic value and agrobiological traits (cold and winter hardiness, yield, anti-phytopathogen resistance, high wine material quality), the Frontenac Gris variety holds promise in industrial viticulture. It can be recommended for gardening in sufficiently humid cool climates avoiding winter bush sheltering, as well as for breeding. The variety is low-hardy to drought and summer heat, which hinders its growing in the southern country. The variety’s disadvantages are in early maturity and slight berries wilting on bush in dry and windy air, which can pose an issue in juice production from pressed berries.

Nowadays, table grape consumers prefer seedless grape varieties, so the market promotion of seedless varieties continues at a rapid pace. Responding to consumer preferences, the breeders have developed numerous various-flavour seedless varieties with large berries and bunches. The study purpose is to assess the prospects of cultivation and use in breeding of a new seedless Regal Seedless grape variety bred in South Africa. By origin, this is an intraspecific hybrid of the species V. vinifera L., with an early middle ripening period. The author carried out the variety study to assess agrobiological, economically valuable traits and properties and compiled a short ampelographic description. The study was carried out in 2017–2019 at the experimental vineyard of Ya.I. Potapenko All-Russian Research Institute for Viticulture and Winemaking – Branch of Federal Rostov Agricultural Research Center. The study focuses on non-irrigated covered and grafted vineyards, the Kober 5BB rootstock, the planting pattern of 3 × 1.5 m, and a fan-shaping thankless bush. As to a set of positive parameters (yield, high vendebility, natural seedlessness without the use of gibberellin, large size characteristics, and good taste), the Regal Seedless variety is of certain interest for industrial viticulture, and this variety can also be recommended for use in further breeding as a source of seedless and large berries. According to preliminary studies, the ripened berries of this variety should not be kept long on the bush to prevent peel browning and deterioration in vendebility. The variety is recommended as a highly commercial table grape without the PPP use, but it is not suitable for the production of raisins due to insufficient sugar accumulation. It is recommended that the variety should be grown in areas of sufficient moisture or as an irrigated crop.

Preserving rare grapes is not just a matter of variety. Recent dna research has shown that unusual and unknown grape varieties provide clues to wine history. During the centuries, 525 Georgian grape varieties had been known but most of them were degenerated. Nowadays, more than 437 rare Georgian vine varieties are preserved in the geo 038 collection of Agricultural Research-Scientific Center, established in 2014 under the Environment Protection and agriculture ministry. Study of the genetic pool of Georgian grape varieties determine the sustainability of the sector and enrichment of the modern wine market. For this reason the studies of the rare aboriginal grape varieties have begun by their ampelography, phenology, chemical, and oeno-caprological characterizes. The aim of this study is to investigate rare, Georgian, aboriginal wine-grapes by their ampelography, chemical and oenolo-caprological characterizes, and to offer different style and aroma wines to the market, enriching the modern wine assortment. The present study investigated firstly the rare Georgian aboriginal grape variety (Chvitiluri) by its characterizes. In this study grapes caprologycal indication, dynamic development of the sugar accumulation, TA and pH in berries, polyphenols extract in skin and seeds, and phenolic compounds were determined. The grape has been compared with Georgian and French wine-grapes and their products as well. The results show that the grape variety - Chvitiluri, and vinification technique (aging on lee) have the significant impact on the total phenol content in wine. White varietal wine contents high alcohol 13,2%, total phenols 733-500mg/l. Wine has specific, varietal characterizes color, taste, aroma. This study indicates that the rare local, aboriginal variety presents the perspective sort for wine production and can be returned in wine production.

Приведены экспериментальные данные оценки по хозяйственно полезным признакам одиннадцати новых партенокарпических гетерозисных гибридов огурца в условиях весенне-летнего оборота Кировской области. Проблема возделывания теплолюбивых культур в северных регионах страны формирует цели селекционных исследований. Выращивание культуры огурца в Кировской области усугубляется неблагоприятными климатическими условиями второй световой зоны (короткая продолжительность вегетационного периода, низкие положительные температуры, заморозки в третьей декаде июля и в первой декаде августа). Цель научной работы – оценка и выявление перспективных партенокарпических гетерозисных гибридов огурца для выращивания в условиях необогреваемых теплиц в весенне-летнем обороте второй световой зоны. Исследования проводили в лаборатории северного овощеводства Кировской области во Всероссийском научно – исследовательском институте овощеводства – филиале ФГБНУ «Федеральный научный центр овощеводства» в условиях поликарбонатных необогреваемых грунтовых теплиц в течение 2018-2019 годах. В результате фенологических наблюдений и оценки биометрических показателей определены раннеспелость, скороспелость и товарность испытуемых партенокарпических гетерозисных гибридов огурца селекции Агрохолдинга «Поиск» и ВНИИО – филиала ФГБНУ «Федеральный научный центр овощеводства»: F1Авоська, F1 Атос, F1 Букет для мамы, F1Малахитовая шкатулка, F1 Мультифрут, F1 Новатор, F1Пилигрим, F1 Спринтер, F1 Реванш, F1 Тонус, F1Экспресс в сравнении с районированным гибридом огурца F1 Каролина. Определено сильное негативное влияние климатических условий второй световой зоны на продолжительность периода «всходы-плодоношение», который в среднем за годы исследований в зависимости от гибрида варьировал от 47 до 55 суток. Установлено, что для получения ранней продукции огурца в условиях поликарбонатных необогреваемых грунтовых теплиц Кировской области следует выращивать гетерозисные партенокарпические гибриды огурца F1Спринтер (3,6 кг/м2), F1 Авоська (2,1 кг/м2) и F1 Атос (2,5 кг/м2). Отмечены партенокарпические гибриды огурца F1 Спринтер и F1 Атос, которые имеют наиболее высокий выход товарной продукции 95,7 и 94,0%, соответственно. Выделен самый урожайный партенокарпический гибрид огурца F1 Новатор (16,1 кг/м2). В результате исследовательской работы рекомендовано выращивать в условиях необогреваемых теплиц весенне-летнего оборота Кировской области партенокарпические гибриды огурца F1 Новатор, F1 Спринтер, F1 Атос и F1 Авоська. The article presents the experimental data on the assessment of economically useful traits of eleven new parthenocarpic heterotic cucumber hybrids under the conditions of the spring-summer turnover of the Kirov region. The problem of cultivation of thermophilic crops, which arises in the northern regions of the country, is one of the stages of breeding research. The cultivation of cucumber in the Kirov region is aggravated by unfavorable climatic conditions of the second light zone (short duration of the growing season, low positive temperatures, frosts in the third decade of July and in the first decade of August). The purpose of the scientific work is to evaluate and identify promising parthenocarpic heterotic hybrids of cucumber for growing in unheated greenhouses in the spring-summer turnover of the second light zone. The research was carried out in the laboratory of northern vegetable growing of the Kirov region at the All-Russian Research Institute of Vegetable Growing - a branch of the Federal State Budgetary Scientific Institution Federal Scientific Vegetable Centre in the conditions of polycarbonate unheated ground greenhouses during 2018-2019. As a result of phenological observations and assessment of biometric indicators, the early maturity, early maturity and marketability of the tested parthenocarpic heterotic cucumber hybrids of the selection of Agroholding Poisk and ARRIVG – a branch of the Federal Scientific Vegetable Centre were determined: F1 Avoska, F1 Atos, F1 Buket dlya mamy, F1 Multifrut, F1 Novator, F1 Piligrim, F1Sprinter, F1 Revansh, F1 Tonus, F1 Express in comparison with the zoned hybrid of cucumber F1 Carolina. A strong negative influence of climatic conditions of the second light zone on the duration of the seedling-fruiting period was determined, which on average over the years of research, depending on the hybrid, varied from 47 to 55 days. It has been established that to obtain early production of cucumber in polycarbonate unheated ground greenhouses of the Kirov region, heterotic parthenocarpic cucumber hybrids F1 Sprinter (3.6 kg/m2), F1 Avoska (2.1 kg/m2) and F1 Atos (2.5 kg/m2). Parthenocarpic cucumber hybrids F1 Sprinter and F1 Atos were noted, which have the highest yield of marketable products, 95.7 and 94.0%, respectively. The most productive parthenocarpic cucumber hybrid F1Novator (16.1 kg/m2) has been identified. As a result of the research work, it was recommended to grow parthenocarpic cucumber hybrids F1Novator, F1 Sprinter, F1 Atos and F1 Avoska under conditions of unheated greenhouses of spring-summer turnover of the Kirov region.

The Russian Research Institute of Floriculture and Subtropical Crops has the citrus germplasm collection, in total over 150 genotypes of various origins including 30 wild and semi-wild relatives. As a result of controlled hybridization in 17 crossings combinations of with the participation of relatives of citrus plants, new 769 hybrid offspring were obtained, which combine the traits of both the maternal and paternal genotypes. Analyzing the populations, promising combinations were highlighted: C. reticulata × Fortunella margarita (47.1%); C. x natsudaidai × 3252 (42.1%) and C. reticulata × C. reticulata ‘Cleopatra’ (40.9%) to create the gene pool of distant hybrids. From the mentioned combinations of crossings the greatest percent of seedlings which phenotypes tend to cultivated varieties was received. This hybrid material is a valuable source for isolating forms that are resistant to extreme environmental factors. According to phenotypic characteristics, hybrids were divided into three categories: I – Cultural, II – Semi-wild and III – Wild. Of the first category, the largest number 87 prospective forms were selected, and can be of interest for further breeding. As a result of the study of interspecific hybrid seedlings, 137 promising forms have been identified, which are carriers the complex traits such as dwarfism, thornless, early maturity and increased winter hardiness. From this set 17 genotypes were selected, which received the status of an elite forms, which successfully pass the primary test, and will be also useful in further breeding work for creating sources with a complex of positive traits and on breeding new varieties of citrus crops resistant to growing conditions.

SUMMARYA decline in supplies of organic manures and the increased use of chemical fertilizers has led to a decrease in the micronutrient content of the soil, with attendant effects on yield.Field studies were conducted in 1986 and 1987 at the Giza Agricultural Research Centre, Egypt, to determine the effect of Cu-EDTA and Mn-EDTA foliar sprays on growth, mineral content, yield components and fibre properties of the Egyptian cotton cultivar Giza 75 (Gossypium barbadense L.).All combinations used significantly increased the uptake of Cu and Mn and the dry matter yield. The earliness of harvest and the value of yield components were all increased by the application of Cu or Mn; 25 mg/1 of both Cu and Mn gave the highest values. Lint percentage and fibre properties were not significantly affected.This study indicated that the yield of cotton, grown under otherwise standard conditions, may be increased by foliar sprays of Cu-EDTA and Mn-EDTA combined.

A field experiment was conducted at Regional Wheat Research Centre of the Bangladesh Agricultural Research Institute, Joydebpur, Gazipur for 2 consecutive years during 2006-07 and 2007-08. The objectives were to find out the optimum nutrient management practice on tuber yield, nutrient balance and economics of potato cultivation. Twelve nutrient management treatments were tested in a randomized complete block design with 3 replications. Treatments were T1=HYG (0-198-44-194-24-6-1.2), T2=MYG (0-140-34-138-18-4.5-0.9), T3=IPNS (10000-168-38-170-18-6-1.2), T4=STB (0-171-40-164-22-5-1), T5=FP (0-97-16-91-0-0-0), T6=CON (0-0-0-0-0-0-0), T7=HYG+CRI, T8=MYG+CRI, T9=IPNS+CRI, T10=STB+CRI, T11=FP+CRI, T12=CON+CRI kg ha-1 CDNPKSZnB for potato. The highest tuber yield of potato was obtained from STB+CRI (27.64 t ha-1) followed by IPNS+CRI (27.35 t ha-1), STB (27.10 t ha-1), IPNS (26.83 t ha-1), HYG+CRI (26.52 t ha-1) and HYG (26.10 t ha-1) in 2006- 07. Similar trend was found in 2007-08. The highest tuber yield and yield contributing parameters were noticed in CRI plots than without CRI. Except N, remaining nutrient balance like P K S Zn and B were found positive in case of HYG, MYG, IPNS and STB along with or without CRI nutrient managements. The balance was found almost negative in case of FP and CON. The highest BCR was observed in STB+CRI (3.96) followed by STB (3.93), IPNS+CRI (3.76), and IPNS (3.74). The higher gross return (Tk. 283331 ha-1) and also gross margin (Tk. 211761 ha-1) was observed from the same treatment. DOI: http://dx.doi.org/10.3329/bjar.v39i4.22544 Bangladesh J. Agril.

Ministry of Agriculture and Fisheries, Research Division, Ruakura Agricultural Research Centre, Hamilton, New Zealand (Received 17 April 1978) An increase in the plasma concentration of luteinizing hormone (LH) occurs in response to castration in bull calves aged 1–4 months; this response is of similar magnitude to that seen in cattle castrated as adults (Odell, Hescox & Kiddy, 1970). In bull calves castrated at birth, however, there is no increase in the plasma concentration of LH until after 28 days of age (Bass, Peterson, Payne & Jarnet, 1977). In other species a range of responses to castration has been reported. Gonadectomy of male guinea-pigs 0–35 days after birth produces an increase in the plasma concentration of LH similar to that observed in guineapigs castrated as adults (Donovan, ter Haar, Lockhart, MacKinnon, Mattock & Peddie, 1975). In contrast, the castration of young male macaques does not cause an immediate increase in the

A field experiment was conducted at the Regional Wheat Research Centre (RWRC) of the Bangladesh Agricultural Research Institute, Gazipur, Bangladesh for 2 consecutive years during 2006-07 and 2007-08 with the objective to find out the optimum nutrient management practice on total dry matter production (above ground part) of each component crop of potatomungbean- t. aman rice cropping pattern. Twelve nutrient management treatments were tested in RCBD with 3 replications. Treatments were, T1=HYG (0-198-44-194-24-6-1.2), T2=MYG (0-140-34-138-18-4.5-0.9), T3=IPNS (10000-168-38-170-18-6-1.2), T4=STB (0-171-40-164-22-5-1), T5=FP (0-97-16- 91-0-0-0), T6=CON (0-0-0-0-0-0-0), T7=HYG+CRI, T8=MYG+CRI, T9=IPNS+CRI, T10=STB+CRI, T11=FP+CRI, T12=CON+CRI kg/ha CDNPKSZnB, for potato; T1=HYG (0-24-40-48-24-3-1.2), T2=MYG (0-20-36- 40-20-2-1), T3=IPNS (5000-9-37-36-21-3-1.2), T4=STB (0-20-36-40-22-2-1), T5=FP (0-6-5-4-0-0-0), T6=CON (0-0-0-0-0-0-0), T7=HYG+CRI , T8=MYG+CRI, T9=IPNS+CRI, T10=STB+CRI, T11=FP+CRI, T12=CON+CRI kg/ha CDNPKSZnB for mungbean and T1=HYG (0-80-16-44-12-2-0), T2=MYG (0-56-12-32-8-1.5-0), T3=IPNS (5000-65-13-32-9-2-0), T4=STB (0- 68-15-37-11-2-0), T5=FP (0-39-37-12-0-0-0), T6=CON(0-0-0-0-0-0- 0),T7=HYG+CRI, T8=MYG+CRI, T9=IPNS+CRI, T10=STB+CRI,T11=FP+CRI, T12=CON+CRI kg/ha CDNPKSZnB for t. aman rice. HYG treatment without or with crop residues incorporation produced the highest TDM in potato, mungbean and t. aman rice followed by IPNS and STB along with or without CRI. The lowest TDM was recorded in control plot without CRI. The increasing trend of TDM was observed in the crop residues incorporation plots than nonincorporation plots. It was observed that there were significant and positive linear relationship between TDM and yield of potao, mungbean, and t. aman rice at 60 DAP, 60 DAS, and 90 DAT, respectively, in both the years.
