To determine the patterns of inheritance and variability of nutmeg aroma in seedlings of hybrid combinations with different genetic bases.\u0000Results and Discussions. Selection of parents and segregation of hybrids were analyzed by expression levels and peculiarities of palatability-aroma complex of seedlings. Breeding analysis of seven hybrid grape combinations obtained from one or from both parents with muscadine flavor was conducted. The expression level and characteristics of muscadine flavor depended on the selection of parents. Several donors of the \" muscadine flavor\" trait have been identified. It was proven that this trait of breeding interest was inherited from old varieties by a greater portion of seedlings in a combination than from complex interspecies hybrids of the new generation. A number of promising seedlings are presented; they were selected by a set of traits of breeding interest: resistance to pathogens, yield, large fruits, and product quality.\u0000Conclusions. Thus, the trait \"muskat flavor\" has a significant heritability in offspring, polygenic nature of inheritance and manifestation. Varieties – donors of muscadine flavor are Kardyshakh Tairovskyi, Marselskyi Chornyi Rannii, and Muskat Odeskyi. In order to obtain a muscadine-lemon aroma, we recommend using Varieties Hechei Zamatosh, Opalovyi and Muskat Odeskyi. Greater segregation of the aroma complex was observed in combinations not only from muscadine varieties, but also from varieties with varietal aromas, especially of the technical use, such as Zahrei, Riton, and Opalovyi.","PeriodicalId":306712,"journal":{"name":"Genetičnì resursi roslin (Plant Genetic Resources)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129189837","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To select references of various expression levels of spike performance constituents and to format a trait collection by yield and performance.\u0000Results and Discussion. Based on the results of three-year research (2017–2019), 104 winter bread wheat accessions were characterized by performance and yield constituents. The geographical diversity of the trait collection of winter bread wheat in terms of performance and yield is represented by accessions from 10 countries worldwide. The majority of the trait collection consists of varieties from Ukraine (66), Russia (16), and Germany (10). The remaining accessions come from Kyrgyzstan, Turkey, France, Romania, Azerbaijan, Slovakia, and Romania. In order to further study and organize the genetic diversity of the crop and to assess trait expression ranges across the studied accessions, references reflecting 10 traits with 36 levels of their expression, in accordance with gradations of the classifier scales, were chosen. Comprehensive evaluation of accessions for a set of valuable economic features, spike performance constituents, and yield opens up an opportunity to create highly productive winter bread wheat varieties.\u0000Conclusions.

Having comprehensively assessed valuable economic traits and pasta properties, we selected sources and reference accessions that significantly enriched the genetic diversity of the National Plant Gene Pool of Ukraine. They served as a basis for a trait collection by pasta properties. The trait collection of winter durum wheat by pasta properties (certificate No. 302 dated December 18, 2020) comprises 50 accessions from ten countries and reflects their diversity in terms of 20 traits and 73 levels of their expression, including flour and dry pasta color, weight increase, volume increase, cooking loss, the total pasta score, protein content in grain, vitreousness, as well as a number of valuable economic traits, in particular, disease resistance, performance, etc. Biologically, 48 accessions are cultivars and two are breeding lines. They represent one botanical species (T. durum Desf.) and four varieties (megalopolitanum, hordeiforme, leucurum, niloticum).\u0000Conclusions. New comprehensively valuable sources with high resistance to biotic factors and high yields (127-164% related to the check cultivar) have been identified: Koral Odeskyi, Pributkova, Passat (UKR); Amazon, Teya, Odari (RUS); and XE 9710 (FRA).

In representatives of hulled wheat species T. monococcum, T. dicoccum cv. Polba 3 and T. spelta cv. Frankenkorn, the seeds with removed hulls had in the control and experimental variants higher germination energy and germination level than the seeds in hulls. In the control variant, the positive reaction to the removal of hulls from the seeds in diploid species T. monococcum was more significant (germination energy and germination level increased respectively by 22% and 13%), than the samples of polyploid species T. dicoccum and T. spelta (increase by 3% – 10%). Under accelerated aging, on the contrary, removal of the hulls had a stronger positive effect in the polyploid species (the increase was from 21.7% to 34.0%) than on the diploid species (the increase was by 2% and 12%). Removing the hulls from the grains of the hulled wheats accessions ambiguously affected the length of the primary roots and leaves. In the control variant, in T. monococcum, length of the primary roots in the dehulled seeds did not change compared to the undehulled seeds; in the emmer and spelt it decreased. Under the conditions of accelerated aging, removal of the hulls affected the length of the primary roots in einkorn negatively, in the emmer and spelt – there was no impact. In most cases, removal of hulls had a positive effect on the primary leaf length, with the exception of the emmer variety Polba 3 in the control – decrease by 1,5%). The possible connection of this phenomenon with the presence of inhibitors in wheat hulls established by researchers is discussed. \u0000Conclusions.

The current state, research results and prospects of using collections of breeding forms of the genus Juglans representatives at the Experimental Breeding Dendrological Forest Center (EBDFC) \"Veseli Bokovenki\" are analyzed. The 2016 survey showed that 7 out of 10 experimental objects derived from the genus Juglans representatives over a 120-year period have been preserved and are in a satisfactory condition within the territory of the Center. They are all in the context of the gene pool value. The Persian walnut (Juglans regia L.) breeding history within the territory of EBDFC \"Veseli Bokovenki\" started with the creation of the Big and Small Kutsivsky gardens by M.L.Davydov in 1900. Planned scientific research into the Persian walnut breeding started here in the 1930s. In different periods of time, under the guidance of A.P.Yermolenko, F.L.Shchepotiev and P.P.Badalov, selection of drought-resistant and winter-hardy forms, interspecies hybridization and studies of reproduction and physiology of the genus Juglans representatives were carried out. Apomictic fruits of the Japanese walnut (Juglans ailantifolia Carriere), heartnut (J. ailantifolia Carr. ssp. cordiformis Rehd), Manchurian walnut (Juglans mandshurica Maxim) and white walnut (Juglans cinerea L.) were obtained. The breeding results were summarized in chapters of the books \"Nut Cultivation\" and \"Nuts\". Recently, studies have focused on reproductive biology of breeding forms. The dichogamy type and laterality degree of the 80 best forms presented on the mother-graft plantation have been determined.

The purpose was to identify collection accessions – sources of valuable traits to use as starting material for creating varieties of perennial grasses in Western Ukraine.\u0000Results and Discussion. Perennial grasses play an essential role in improving the efficiency of forage production.

Кhomiak","doi":"10.36814/pgr.2022.31.08","DOIUrl":"https://doi.org/10.36814/pgr.2022.31.08","url":null,"abstract":"Aim. To identify collection accessions – sources of valuable traits for using as starting material to create varieties of perennial grasses in Western Ukraine. \u0000Results and Discussion. The vegetable protein problem is one of the main issues facing scientists whose activities are related to agriculture, ecology and other areas of biology. The Ciscarpathia is a zone of natural meadows, hayfields and pastures, where a large number of plant species belonging to different botanical families grow. Among the natural vegetation on pastures, meadows and fallows, clover species are most often found. Trifolium incarnatum L. is an annual winter-spring plant. It is widely used in agriculture as a nitrogen-fixing cover crop. The crimson clover collection comprises 24 accessions. Some promising accessions that can be used as starting material in breeding for high productivity (green mass, hay and seeds), herbage capacity, resistance to diseases and pests were selected. Reference accessions and sources of economically valuable traits, which are actively involved in breeding, were singled out. During the study (2019-2021), accessions were investigated in detail for biological and morphological features. We evaluated the crimson clover collection for germinability, winter survival, flowering time, green mass per plant, and seed yield. The results showed that the crimson clover collection could be tentatively divided into 3 groups: early-ripening (70-79 days; 37.5%), mid-ripening (83-87 days; 50.0%) and late-ripening (92-94 days; 12.5%). Nine accessions (PFZ 00625, PFZ 02148, PFZ 01264, PFZ 01266, PFZ 01295, PFZ 01273, PFZ 01270, PFZ 02266, and PFZ 02265) ripened slightly earlier. They are potential parents to develop an early-ripening population. Three accessions (PFZ 02268, PFZ 02267, and PFZ 02073) ripened significantly later than all the others. Thus, these accessions are excellent candidates to develop a late-ripening population. Depending on the region and cultivation system, farmers may be interested in both early-ripening and late-ripening crimson clover.\u0000Conclusions. Literature review allowed us to note that the studied crimson clover accessions had several advantages when used in production, namely: they are annuals, have high vegetation rates and productive potentials. Crimson clover accessions showed particularly distinct differences in autumn emergence and flowering time, indicating greater diversity and potential for breeding. In contrast, winter survival, green mass per plant showed greater intra- and inter-year variations. Autumn emergence and winter survival were found to be positively correlated, and both traits were negatively correlated with green mass per plant. Some accessions were identified as highly effective in several key traits and are of particular interest as parents in further breeding: PFZ 02118, PFZ 01270, PFZ 02267, PFZ 02073, PFZ 02072, PFZ 01290.","PeriodicalId":306712,"journal":{"name":"Genetičnì resursi roslin (Plant Genetic Resources)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130741995","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
