Abstract The paper proposes the improvement of the current bitter cherry assortment with new creations made at Iaşi, adapted to the specific conditions from the NE area of Romania. For the improvement of the bitter cherry assortment with new, productive, disease resistant cultivars with fruits of good quality, resistant to cracking with different maturation stages, in 1981 at Fruit Growing Research Station (F.G.R.S.) Iaşi - Romania has begun an action of selection and promoting of some valuable genotypes of bitter cherry (existent in the spontaneous flora or in plantations from the Iaşi county), which were being planted with cultivars and other genotypes from all around the country. Following the positive and gradual selection there were selected three biotypes of bitter cherry from which two of them have been approved as new cultivars in 1994, with the names „Amar Maxut”, respectively, „Amar Galata” and the biotype „Amar R5.P10” has been registered in 2013 at the State Institute for Variety Testing and Registration Bucharest to be approved as a new cultivar. All three bitter cherry genotypes correspond to the objectives of the main assortment breeding. They have a high productivity because the natural fertility index registered values between 36.5-63.7%, the trees have a reduced vigour, they present a good resistance to frost (1-9% affected buds) and to diseases (values of I% anthracnose, 1.1-2.8%). The fruits are high quality and the maturation stages are at the extremities of the cherries maturation season.

The promotion of a cherry assortment with constant yield, low vigour of the trees, self-fertility and high productivity, resistance to biotic and abiotic factors and with ripening at the extremities of the cherries maturation season, represents a permanent concern of researchers. In this context, considering the current patrimonial situation and the perspectives of growing sweet cherry trees in the Iasi area, under a privatized agriculture, the selection of new cultivars to be introduced in the assortment requires a special attention. Analyzing the values of the fertility index during the three years of study (2018 – 2020) it was observed that all the cherry cultivars excepting ‘Kordia’ are highly fertility with values between 30.0% and 66.2%. The cultivars ‘Bucium’, ‘Croma’, ‘Van’, ‘Maria’, ‘Stella’, ‘Cătălina’, ‘Margonia’ and ‘George’ have large fruits (over 7 g and over 22.5 mm) and ‘Kordia’ (6.3 g and 21.1 mm), ‘Scorospelka’ (6.2 g and 22.3 mm), ‘Cetăţuia’ (6.0 g and 22.0 mm) and ‘Rivan’ (5.9 g and 21.6 mm) have small fruits. For ‘Scorospelka’, ‘Cetăţuia’ and ‘Rivan’, the fruits are large in comparison with other early cultivars. The values of soluble dry substance (SDS) varied between 13.6% (‘Scorospelka’ and ‘Rivan’) and 18.9% (‘Maria’). However, statistically, cultivars ‘Maria’ (18.9%), ‘Bucium’ (18.3%) and ‘George’ (18.1%) recorded superior values in comparison with all the other cultivars.

Sweet Cherry Cultivars

The research concerning the improvement of the cherry assortment, the cultivars’ quality and the avoiding of market crowding with fresh cherries only on a short term are extremely important objectives for cherries’ breeding. To accomplish some of these objectives, during 1981-2017, hybridization and selection of hybrids were performed at the Research Station for Fruit Growing Iași (RSFG Iași), in the N-E part of Romania, concluding with a series of promising hybrid selections. They have been grafted, planted and studied in trial fields. Therefore, during 1994-2016, RSFG Iași released 28 sweet cherry cultivars with high quality fruits and different maturation stages. In the studies performed during 2014-2017, there were analysed three new sweet cherry cultivars (‘Elaiaşi’, ‘Muşatini’ and ‘Croma’), obtained through controlled hybridization. The comparison of these new cultivars was performed against ‘Van’, used as control, this being a well-known cultivar in the orchards from the study area. Observations and measurements concerning the main phenological stages, natural fertility, physical features, organoleptic, quality and chemical traits of fruit were registered. The cultivars with the biggest dimensions of the fruits were ‘Elaiaşi’ and ‘Croma’ (with a weight between 8.9 and 9.4 g and a fruits’ diameter between 25.2 and 26.6 mm), having significantly larger dimensions in comparison with ‘Van’. In the new investigated cherry cultivars, the values of soluble solids content were comprised between 17.0 and 20.2 °Brix, titratable acidity was between 0.46 - 0.57 mg of malic acid 100 mL-1 juice and the total polyphenols content was recorded between 382.87 - 780.25 mg GAE 100 mL-1 of fresh juice.   ********* In press - Online First.

Abstract The studies were performed for four consecutive years (2016–2019) at the Fruit Growing Research Station (North-East part of Romania), using eleven sweet cherry genotypes as research material. Five of them are new cherry cultivars – ‘Cătălina’, ‘Andreiaş’, ‘Maria’, ‘George’, and ‘Margonia’ – obtained by means of controlled hybridization or open pollination, and six of them are their progenitors (‘Van’, ‘Boambe de Cotnari’, ‘Stella’, ‘Fromm’, ‘Ciliegia di Ottobre’, and the ‘HC 27/4’ hybrid). The experiment compared the traits of new cultivars with those of their progenitors. The following traits were evaluated: tree vigor, frost damage, the phenological stages, and the physical and chemical traits of the fruit. The highest values concerning the fruit's weight have been recorded for ‘Andreiaş’ (10.0 g) and ‘Maria’ (7.6 g), the content of soluble substance was between 16.6 and 19.5°Brix, the titratable acidity was between 0.413 and 0.675 mg malic acid·100 mL−1 juice, and the total content of polyphenols was recorded with values between 268.00 and 488.75 mg GAE·100 mL−1 of fresh juice. The new cultivars have mostly superior traits, especially frost damages, productivity, fruit quality, and fruit's cracking percentage compared with their parental genotypes.

The soil and climate conditions in Romanian Northeastern area are favorable for cherry cultivation, but some times can occurred some calamities. The paper presents a study which during 2020 at the Research Station for Fruit Growing (N-E of Romania), using five sweet cherry genotypes as research material: ‘Van’, ‘Croma’, ‘Elaiași’, ‘HC920402’, ‘HC930208’. Observations and determinations were performed in regards to the frostdamages, the main growing and phenological stages and the physical and chemical traits of the fruit. The phenological stages were evaluated for beginning of flowering and fruit ripening (expressed in growing degree-days, GDD). For these sweet cherry cultivars, the highest values concerning the fruit’s weight have been recorded for ‘Elaiași’ (9.15 g) and ‘HC920402’ (7.7 g), while fruit’s equatorial diameter have ranged between 23.21 mm and 25.16 mm. The content of soluble dry solids (SDS) was between 14.6 and 20.2 °Brix. The proposed objective aims at introducing in the assortment the new varieties with quality fruits and their resistance to cracking, with ripening time at the extremities of the sweet cherry season.

The paper is devoted to the centenary of the L.P. Symyrenko Research Station of Pomology foundation. The authors have depicted the main stages of the institution formation and development and elucidated its principal scientific achievements. The history of the station began with the creation of the greatest in Russian Empire nursery farm by the outstanding Ukrainian pomologist Levko Platonovych Symyrenko near Mliiv (the now Cherkasy region). As early as in 1912 the cultivars of different plants numbered almost to 3 thousand here. On November 25, 1920 according to the decision of the Board of the People's Commissariat of Agriculture of the Ukrainian SSR the Mliiv Horticultural and Truck Gardening Research Station was created on the basis of the above mentioned nursery. Its first director was L.P. Symyrenko’s son Volodymyr Levkovych, who embodied the creative ideas of the great-grandfather, grandfather and father, realized the cause of several generations of the Symyrenkos. He was a real founder of the Ukrainian horticulture, namely: created and developed all the attributes of Ukrainian pomology, systems of research institutions and state nurseries and the State "Pomological Book". V.L. Symyrenko, professors L.M. Ro and V.P. Popov, research worker M.A. Grossheim and others were major organizers of the station. With their direct participation the departments of horticulture, vegetable growing, entomology, agricultural meteorology, phytopathology, technical processing of fruits and small fruits, agrochemistry ets. were founded and functioned by 1927 already. In 1958 the station was named after L.P. Symyrenko. In the April of 1989 on the initiative of its then director M.M. Artemenko and with the support of the scientific collective it was reorganized as the Mliiv L.P. Symyrenko Research Institute of Horticulture of the Lisosteppe of Ukraine, in 1992 in accordance with tho order of the Presidium of the Ukrainian Academy of Agrarian Sciences (UAAS) renamed as Mliiv L.P. Symyrenko Institute of Horticulture of UAAS and in 2006 as L.P. Symyrenko Institute of Pomology of UAAS. In 2017 it was reorganized as the L.P. Symyrenko Research Station of Pomology of the Institute of Horticulture of the National Academy of Agrarian Sciences (NAAS). Today, it is one of the leading scientific institutions of the NAAS system in the horticultural branch. The scientific and research works are carried out in conformity with the four scientific and technical programmes of NAAS: “Genetical Resources of Plants”, “Horticulture and Small-Fruit Growing”, “Plant Protection” and “Agrarian Economics”. The main direction of the institution research activity is the elaboration of the scientific basis of the preservation and spread of the genetic versatility of the fruit, small fruit, nuciferous and minor crops. At present more than 3,000 varieties of fruit, small fruit, nuciferous and ornamental crops are studied in the collectional plantations. That is the valuable genetic fund of Ukraine. Today 72 varieties bred by the Mliiv Research Station have been entered into the State Register of the Plant Cultivars Favourable for the Spread in Ukraine.
