The purpose of the study is the application of the method of multi-criteria estimation to select the initial material of various direction of maize breeding. The studies were performed in the year of 2017–2018 in two different regions of trials, in the arid area of the ARC “Donskoy” (Zernograd) and in the moisture area of the All-Russian Research Institute of Maize (Pyatigorsk). 10 parental forms of maize hybrids ‘Alpha M’, ‘Almaz M’, ‘Avrora S’, ‘Milena M’, ‘Istok S’, ‘Mirt M’, ‘Malvina S’, Raduga S’, Maya M’, ‘Prestizh M’ used as testers in breeding programs were taken as initial material. The studied forms were characterized by a diversity in the value of their main economically valuable traits. Significant variability was identified in infertility of plants (V = 56.0%), smut infection (V = 46.4%) and fragility of a stem below a cob (V = 43.4%). Average variability was identified in grain productivity (V = 14.8–18.2%), drought resistance index (V = 10.5%), harvesting moisture of grain (V = 18.6%). The use of the complex of main economically valuable traits for the integrated assessment (SD), taking into account the specified contributions (Rk) and weight coefficients (Wi), made it possible to rank the initial material according to its value for various areas of selection. There have been identified the testers ‘Mirt M’, Maya M, ‘Istok S’ with the best integral values (SD = 2.63–5.65) for breeding on drought tolerance. ‘Istok S’, ‘Milena M’, ‘Avrora S’ (SD = 2.14–4.07) have been recommended as the testers in breeding programs to breed the varieties with low harvesting moisture of grain. There has been identified a universal tester ‘Istok S’ which is suitable for various directions of maize breeding. Thus, the multi-criteria estimation can be used in the breeding process to select initial material that meets the requirements of the planned breeding directions.

The production of quality products and their efficiency is a pressing issue today. The solution of which is inextricably linked to the introduction of new varieties with a high content of antioxidants, pectins, which have healing and preventive properties. To conduct research in 2016 - 2018 at the L.P. Symyrenko experimental station IS NAAN the following varieties of cherry fruits were selected: Alpha, Zhadan, Chance, Elegant, Artemenko Memory, Optimist, Podbelskaya. The cherry was harvested in the consumer stage of ripeness during the first decade of July. According to the complex of physicochemical and organoleptic parameters, the selection of the best variety of cherry fruits was performed by the method of multicriteria optimization. The aim of the work was, on the basis of a comparative analysis of a set of physicochemical and organoleptic indicators of cherry fruits, using multicriteria optimization, to determine the best varieties recommended for production. The results of studies showed that the weight of cherry fruits ranged from 4,2 to 5,2 g. The content of soluble solids in cherry fruits was at the level of 15,26–15,89% and was predominant for cherries in Artemenko memory and the lowest in Podbelska variety. The sugar content of cherry fruits was 10,14 −10,96%. The level of titratable acids that determine the taste of cherry fruits together with the gourds is in the range from 1,67 to 2,02%. It is the highest for cherry fruits of the Artemenko memory, and the lowest for the Elegant variety. The cherry fruits of the experimental varieties have a significant content of ascorbic acid − 19,15−16,25 mg/100 g. The cherries of the Artemenko memory, and the lowest of the Optimist variety, prevail in the fruits. The tasting rating of cherry fruits is 8−8,7 points. According to the complex of the mentioned above physicochemical and organoleptic indicators by the method of multicriteria optimization such varieties of cherry fruits as Artemenko Memory, Alpha and Zhadana are recommended for production implementation

The article considers the results of experiments on the study and selection of sources of valuable features from the world collection. The aim of the research is to create new varieties of winter triticale with high features of productivity (over 12 t/ha) and grain quality in comparison with the Victor and Hermes standards. Special attention in the experiments is paid to the search for genotypes that are promising for use in breeding programs for different types of crossing, obtaining hybrid populations, identifying forms, lines with a complex of economically useful features. Breeders of Federal Research Center “Nemchinovka” for a number of years received varieties of winter triticale, competitive in Russia and abroad, able to form a crop of more than 10 t\ha of quality grain. However, their disadvantages are tallness, susceptibility to dangerous diseases (snow mold, septoriosis), and significant variability in grain harvest over the years (2.9). The authors have identified sources of economic and valuable features from the collection of N. I. Vavilov All-Russian Institute of Plant Genetic Resources. This includes the winter-hardy variety Tsekad 90, drought-resistant Doctrina 110, short-stemmed Legion, Kentavr, yielding large-grain Efremovskaya, etc., successfully used in breeding. Highly productive lines have been created (No.6 408-19-71, No.618-176, No.878-1-25, No.690-1-19) and varieties (Gera, Kapella, Arktur) with a fixed grain harvest of more than 10t\ ha, adaptive to the natural conditions of the non-Chernozem zone and the middle Volga region.

Tomato Molecular MarkersTomato (Solanum lycopersicumL.) is one of the most popular vegetable grown in many regions of the world. Due to its high taste quality and nutritional value increase interest in the cultivation of this species and its consumption. Using the latest achievements in fields of genetics, molecular biology and biotechnology, breeders can create new varieties with improved useful traits. Introduction of DNA markers, especially those based on the polymerase chain reaction (PCR) has led to breakthrough in the plants genetic research, including tomato. They are successfully used for plant genomes mapping, phylogenetics studies, selection of parental forms in plant breeding, and above all to identify the genes of important traits. For tomato have been identified and mapped 9309 molecular markers. High-density genetic maps development gives an opportunity to use them in genetic research and breeding programs. Identification of DNA markers closely linked to studied gene can significantly facilitate the identification of desirable traits in material breeding, or accelerate the plants selection for elimination of genotypes with undesirable genes. Material breeding selection using molecular markers, defined as MAS (marker-assisted-selection) is increasingly being used in tomato breeding programs, contributing to facilitated identification of genes or QTL and their transfer into the cultivated species from wild form.

The effects of climate change on traditional stone fruit producing areas, together with the generation of new varieties with lower chilling requirements that allow the cultivation of previously unexplored areas, are setting up a challenging scenario for the establishment of productive orchards that must be more efficient in their capacity to adapt to new edaphoclimatic conditions. In this context, the rootstock breeding programs are a key piece in the agronomic strategy to achieve this adaptation through the development of rootstocks compatible with the new varieties and capable of transferring their tolerance to stress. An effective categorization of phenotypes within the germplasm involved in a plant breeding program is of utmost importance. Through the measurement of physiological parameters in both roots and leaves, tolerance to saline stress (120 mM NaCl) was evaluated in seven Prunus rootstocks whose genetic background included representatives of the subgenera Prunus, Cerasus, and Amygdalus. To group the genotypes according to their physiological performance under salt stress, an agglomerative hierarchical clustering was applied. The genotypes were grouped into three clusters containing rootstocks very sensitive (‘Mazzard F12/1’), moderately tolerant (‘Maxma 60’, ‘Cab6P’ and ‘AGAF 0204-09’), and tolerant (‘Mariana 2624’, ‘Garnem’ and ‘Colt’) to salt stress. ‘Mariana 2624’, a plum-based rootstock, was identified as the most tolerant Prunus rootstock. The information reported is valuable both in the productive context, for the selection of the most appropriate rootstocks to establish an orchard, and in the context of plant breeding programs, when choosing parents with outstanding traits to obtain progenies tolerant to salt stress.
