The scab is a widespread disease throughout the world causing large financial losses in apple production and needs to be controlled also by developing polygenic varieties with resistance to several races of the pathogen Venturia inaequalis by incorporation of two or more functionally different resistance genes. The studies for evidence of interest genes relating to the resistance of apple varieties to apple scab have been conducted using several types of molecular markers (SCAR, SSR, RAPD, ISSR etc.). In this experiment, using six SSR molecular markers (CH02b10, CH05e03, CH02d01, Hi07f01 and Hi07h02), was tracked the reveal of amplified fragments, corresponding to PCR products associated with resistance genes Rvi2, Rvi8, Rvi5 and Rvi11, but also the intraspecific diversity expressed at the molecular level of Romanian apple varieties, some of them having common genitors. The position of the amplified fragments on the agarose gel for the six SSR markers was located on similar values ranges to those published in various specialized papers, the size of the amplified fragments following to be evaluated by the sequencing step and published in a new paper as an addition to the results of this study.

Weed control in raspberry cultivation helps to reduce the economic impact of the weed control link on the technological cycle, as well as to eliminate competition for water, nutrients and sunlight, thus allowing their growth and development in normal parameters. Cultivation, mulching and herbicide are the most practical control measures. It is necessary to know both the density of weeds and the dominant species in order to establish the strategy to reduce weeding by plowing, herbicide or integrated measures, so that weed invasion falls below the economic damage threshold (PED). The application of herbicides to reduce the degree of weeding is based on the knowledge of the weed species existing in the crop, as well as the state of coverage of the plantation. In order to establish effective measures to reduce the invasion below the economic damage threshold, it is necessary to determine the density of weeds by the method of mapping them and to establish the predominant species. The mapping action took place in the period 2020-2021 and an attempt was made to cover the entire spectrum of weeds in the plantation, then averaging by species. Following the mapping of weeds in the raspberry plantation, the presence of 22 weeds identified inside the metric frame belonging to both the dicotyledonous and monocotyledonous classes was observed, most of them coming from the first group (Capsela bursa-pastoris, Lamium amplexicaule, Cirsium arvense, Cardaria draba, Setaria glauca, Agropyron repens, Cynodon dactylon.
树莓种植中的杂草控制有助于减少杂草控制环节对技术周期的经济影响，并消除对水分、营养物质和阳光的竞争，从而使其在正常参数下生长发育。栽培、覆盖和除草剂是最实用的控制措施。为了制定通过犁地、除草剂或综合措施减少杂草的策略，使杂草入侵降至经济损失阈值（PED）以下，有必要了解杂草的密度和优势物种。使用除草剂来降低除草程度是基于对作物中现有杂草种类的了解以及种植园的覆盖状况。为了制定有效措施，将入侵减少到经济损失阈值以下，有必要通过绘制杂草密度图的方法来确定杂草的密度，并确定优势种。测绘行动发生在2020-2021年，试图覆盖种植园中的所有杂草，然后按物种平均。在对树莓种植园中的杂草进行绘图后，观察到在公制框架内发现的22种杂草属于双子叶和单子叶，其中大多数来自第一组（Capsela bursa pastoris、Lamium amplexicule、Cirsium arvense、Cardaria draba、Setaria glauca、Agropyron repens、Cynodon dactylon）。

The Persian walnut or English walnut (Juglans regia L.) is a commonly grown species for nut production and noble wood. The nut is one of the oldest food and traditional medicine sources. The native and commercial walnut genotypes present a large diversity that differ widely in nut productivity and quality. However, genetic erosion poses a serious threat to this tree. Several researches of walnut genetic diversity are being carried out utilizing morphological, biochemical, and molecular approaches in order to select superior walnut cultivars of different agroclimatic areas to increase nut production and quality. Genetic resource evaluation and agrodiversity conservation have a major role in ensuring food security for future generations through a continuous supply of new rootstocks and improved cultivars.

During 2020 – 2022, observations and determinations regarding the growth and fruiting at 25 plum genotypes from the Pomological Collection of RIFG Pitesti - Mărăcineni were carried out in order to identify the phenological and morphological diversity, useful to the breeding program. The variability of phenological and morphological characters has a strong genetic determinism, in correlation with the evolution of pedoclimatic conditions. In the context of climatic changes, it has been essential to understand the mechanism of interaction between the genes involved in manifesting characters and traits responsible for the adaptability and productivity of the variety and the environmental conditions. The evaluation was carried out on 100 trees (4 trees/genotype), analyzing 3,000 leaves of leaves, fruits, shoots and flowers, the working volume being over 15,000 measurements and observations. Plum is a vigorous or semi-vigorous species, but 'Centenar' and 'Zamfira' show a fairly clear difference in vigor compared to the other varieties, and this can be an advantage for these varieties when used in high-density orchards. The beginning of flowering started early in the case of two varieties ('Lama' and 'Scolduș'), medium and late for most varieties and very late for 'Grase românești', 'Vinete românești' and 'Vinete românești cl. 300', while beginning of fruit ripening occurred very early for 'Early Rivers', early in the case of 7 varieties ('Centenar', 'Tita', etc.), medium or late for 14 varieties ('Anna Spath', 'Black Diamond', 'Stanley' etc.) and very late in 'Haganta', 'Topend' and 'Renclod Violet'. Also, most of the selected CPVO descriptors were polymorphic and showed more than two phenotypes a high diversity was observed between characters regarding the flower, leaf, shoots and tree habit of the 25 studied genotypes, proving that each of them presents special characters that can be useful in future breeding programs.

The fruits of Aronia melanocarpa (Michx.) Elliot are recognized for their many benefits on the human body due to their medicinal and nutritional qualities. In order to ensure the need for propagating material recently requested by the market, an attempt was made to make the multiplication more efficient. Classical methods of multiplication have given poor results, which has led to the approach of multiplication by in vitro cultures. The varieties of interest were Nero and Melrom. The research carried out so far has established effective culture media for the initiation, multiplication and rooting phases as follows: MS mineral salts and LS vitamins with a hormonal balance consisting of GAɜ, BAP and IBA for the initiation and multiplication stages. The phytohormones GAɜ and IBA were used for rooting. The regeneration of the explants in the initiation stage reached an average of 86%. The multiplication rate was on average at Nero of 6 shoots / explant and at Melrom 12.6 shoots / explant. The rooting on the established in vitro culture media was 97% for Nero and 80.19% for Melrom. The acclimatization percentages were 92.15% for Nero and 90.41% for Melrom. In vitro propagation of Aronia melanocarpa (Michx.) Elliot has proven to be the method that gives the best results for the multiplication of this species.

The pear (Pyrus communis) breeding at the Research Station for Fruit Growing (RSFG) Voinesti, Romania began in 1950, but since 1960 it has been introduced as the main selection objective, resistance to the main diseases and pests along with other agrobiological and technological characteristics. The main source of resistance to disease and pests is some cultivated biotypes with genetic ancestry in Pyrus serotina. Over a period of more than half a century, a vast biological material was selected, which served to register, between 2004 and 2021, 7 pear varieties: 'Corina' (2004), 'Orizont' (2004), 'Tudor' (2007), 'Romcor' (2009), 'Cristal' (2009), 'Aroma' and 'Andrei' (2021), who cumulated in their genotype the most qualities established for selection. There are also many perspective selections in the test cultures field trial.

The aim of this paper is to present valuable features of sweet cherry cultivars with different maturation ages of the fruits approved at RSFG Iasi between 2017 to 2021. Due to its fruits ripening age being earlier than other fruit-growing species (beginning with May), the cherry represents the first link in the annual chain of fruits production. Analysing the bloom phenophase, it was noticed that the cultivars Margonia and Croma bloom period was about two weeks later than the other cultivars. The maturation age of the fruits was spread over 57 days, starting on May the 21st for cultivar 'Cătălina', ending on July 16th for cultivar 'George'. Statistically, in terms of fruits weight (g) and equatorial diameter (mm), cultivars 'Alexus' (9.4 g and 26.6 mm), 'Elaiaşi' (8.8 g and 25.4 mm), 'Croma' (8.0 g and 24.2 mm), 'Maria' (7.8 g and 23.7 mm) and 'Tereza' (7.8 g and 25.4 mm) were highlighted with superior significant differences in comparison with the control cultivar 'Van' (7.4 g and 25.2 mm). In terms of the fruits content in soluble dry substance, cultivars 'Tereza' (19.2%), 'Alexus' (18.6%), 'Maria' (17.8%) and 'Cătălina' (17.8%) recorded superior significant values in comparison with the control cultivar 'Van' (17.7%). All the studied cultivars presented superior resistance to the fruits cracking phenomenon in comparison with the control cultivar 'Van' (41.8%) recording values below 16%.

Blackberries are an important commercial fruit crop, widely grown. The blackberries contain significant amounts of polyphenol antioxidants such as anthocyanin pigments linked to potential health protection against several human diseases, so the demand is increasing. In order to identify the most suitable varieties for the Vlasia Plain area, in 2020 an experimental plot with 6 stable accessions was established. The cv. ‘Chester’, ‘Dar 8’, ‘Navaho’,‘Polar’, ‘Thornfree’, ‘Triple Crown’, were planted in a plantation scheme 3.0 m × 1.0 m. For each variety, during 2021, ripened fruits were harvested and biometric determinations have been done in the laboratory, being measured fruit weight and diameter, firmness, titratable acidity and pH, all fruit quality indicators. The preliminary results showed that blackberry varieties without thorns are larger than thorny varieties and more suitable for fresh fruit consumption, while the ‘Dar 8’ fruit are not so fragrant, their pulp is stronger, so they are more suitable for processing.

The blackberries contain significant amounts of polyphenol antioxidants such as anthocyanin pigments linked to potential health protection against several human diseases, so the demand is increasing. In order to identify the most suitable varieties for the Vlasia Plain area, in 2020 an experimental plot with 6 stable accessions was established. The cv. ‘Chester’, ‘Dar 8’, ‘Navaho’,‘Polar’, ‘Thornfree’, ‘Triple Crown’, were planted in a plantation scheme 3.0 m × 1.0 m. For each variety, during 2021, ripened fruits were harvested and biometric determinations have been done in the laboratory, being measured fruit weight and diameter, firmness, titratable acidity and pH, all fruit quality indicators. The preliminary results showed that blackberry varieties without thorns are larger than thorny varieties and more suitable for fresh fruit consumption, while the ‘Dar 8’ fruit are not so fragrant, their pulp is stronger, so they are more suitable for processing.

The research conducted within the Research Station for Fruit Growing Voinesti during 2019-2021 highlight the performance traits of some apple varieties grown in a high-density system which is widely extended at the private producers in the Dambovita fruit growing area. The extension and moreover the generalization of this high-density system for apple with the following abroad varieties: 'Gala', 'Red Gala', 'Pinova', 'Braeburne', 'Granny Smith', 'Jonaprince', 'Goden Delicious' grafted on 'M9' rootstock, remarked by high productivity and quality of fruits. The regular annual yields of 35-40 t/ha match the producer’s expectations and consumers too. In the same time, there are emphasized new and old apple breds from Voinesti Research Station which proved a great scab resistance and has a big potential for the high-density growing system. The option for genetic resistance of apple varieties is steadily increasing in the high density orchards due to the economic efficiency and possibility to produce ecological fruits.
