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. Based on the results of the 2017–2019 studies of the winter bread wheat accessions, references for 10 traits with 36 levels of their expression were selected.

Among wild species accessions, sources of resistance both to late blight of tubers and to Fusarium dry rot were identified. Solznum vernei, S.ocadae, S.dodsii, S.venturii, and S.boliviense accessions had tubers with high resistance to P.infestans. In addition, 31 accessions of wild species with high resistance to F.sambucinum were identified. Among newly created backcrosses of multispecies hybrids, 31 accessions were distinguished due to high or very high resistance of tubers to the pathogen.

To identify new sources of winter durum wheat by valuable economic traits, to determine relationships between pasta properties and to form a trait collection on this basis.\u0000Results and Discussion. 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). Lainer (UKR); Zolotko, Yakhont (RUS); Sani Bugda (AZE); Saturn 1 (BGR); XE 9710 (FRA), and others were noticeable for high values of the total pasta score. High vitreousness was recorded for Zolotko and Kurant (RUS). High protein content in grain was intrinsic to Zolote Runo (UKR), Kondurum (ROU) and others. The above-listed accessions are valuable starting material for creating new promising cultivars. It was found that there were significant correlations (P<0.01) between the total pasta score and dry pasta color (r = 0.66), between the total pasta score and cooked pasta volume (r = −0.53) and between the total pasta score and cooked pasta weight (r = −0.52).","PeriodicalId":306712,"journal":{"name":"Genetičnì resursi roslin (Plant Genetic Resources)","volume":"200 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":"132749364","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}
