Krasulia","doi":"10.36814/pgr.2021.28.09","DOIUrl":"https://doi.org/10.36814/pgr.2021.28.09","url":null,"abstract":"Aim. To identify sources of several valuable economic and biological traits among new Ukrainian and foreign cultivars.\u0000Results and Discussion. The weather in the spring of 2019 and 2020 contributed to the epiphytotic development of scab, which allowed for assessment of susceptibility of new cultivars to this disease and for identification of sources of high resistance to it. There were no pathogen signs in immune cvs. Harant, Goldrush, Topaz, and William's Pride, which are carriers of the scab resistance oligogen (Vf). No cultivars that would be consistently highly-resistant to this disease in the field have been found. The creation of cultivars with a columnar crown remains a promising trend in breeding. Cv. Ruslan is a columnarity source. As to fruit yield, the leaders were Elise, Geneva Early, Goldrush, Honeycrisp, Pilot, and Topaz. Cvs. Harant, Ruslan, Elise, William's Pride gave stable fruit yields. Cvs. Kakhovske, Alionushkino, Julia, Honeycrisp, and Topaz give yields every year. Cvs. Harant, Malakhit and Rubin are sources of large fruits. Cv. Harant is noticeable for stable expression of this trait, which makes it a reference of large fruits. Mid-sized apples are considered the most optimal for selling. The sources of this trait are cvs. Ruslan, Elise, Honeycrisp, Szampion Arno, and Topaz. Most of the studied cultivars have round or flat-round fruits. Kakhovske apples are distinguished by their unordinary oval (sinapoid) shape. Sources of several features that determine highly-attractive appearance of their fruits have been distinguished. These are cvs. Harant, Malakhit, Ruslan, Elise, Geneva Early, Honeycrisp, Rubin, and William's Pride. Apples of cvs. Kakhovske, Elise, Honeycrisp, Rubin, and William's Pride are characterized by excellent palatability. Cultivars that are sources of several valuable economic and biological traits have been selected.\u0000Conclusions. Modern apple cultivars are starting material for creating new cultivars that will meet the future requirements. Cvs. Harant, Ruslan, Elise, Honeycrisp, Topaz, and William's Pride are sources of the maximum number of selectively valuable traits. By crossing them with cvs. Kakhovske, Malakhit, Alionushkino, Geneva Early, Goldrush, Julia, Pilot, and Rubin, it is possible to obtain genotypes with various ripening periods, which would combine immunity to scab, compact crown, high and stable yield, and high quality fruits.","PeriodicalId":306712,"journal":{"name":"Genetičnì resursi roslin (Plant Genetic Resources)","volume":"56 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":"116203246","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}

Establish the influence of nutritional background on the productivity and grain quality of pea varieties in the conditions of the eastern Forest-Steppe of Ukraine. \u0000Results and Discussion Oplot, Tsarevych and Haiduk varieties yield did not differ significantly (2.18-2.21t/ha), the lowest (1.98t/ha) was established for Malakhite variety on unfertilized background under conditions of 2018-2021. The same trend was noted on the background of the main application of N30P30K30, when with an average yield of varieties was 2.59 t/ha, the difference was only 0.06-0.12t/ha, while for Malakhite it was significant smaller by 0.30 t/ha. The application of mineral fertilizers of N30P30K30 provided an increase in the productivity of the studied varieties an average by 0.45 t/ha or 21.0%. At the same time, Haiduk and Tsarevych varieties stood out, the increase in grain yield was 24.3% and 23.2%, respectively. Protein content in the grain of the varieties ranged 20.1%-20.6% in the variants without fertilizers and on the background of the main application of N30P30K30 was 19.9%-23.2% on average over the years of research. Regardless of the nutritional background, an increase in the productivity of pea varieties led to a decrease in grain protein content. The possibility of a simultaneous increase in yield and protein content in the grain for Haiduk variety on a fertilized background has been established. \u0000Conclusions. Thus, average over the 2018-2021, the highest level of yield was provided by Tsarevych and Haiduk varieties, which is associated with their higher responsiveness to fertilizers and, as a result, resistance to adverse weather conditions during the growing season.","PeriodicalId":306712,"journal":{"name":"Genetičnì resursi roslin (Plant Genetic Resources)","volume":"1 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":"128995833","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 study the genetic diversity of rice in terms of resistance to disease, to find sources of resistance, to select reference varieties and to form a trait collection of rice accessions with resistance to Pyricularia oryzae Cav.\u0000\u0000Results and Discussion. The study was carried out in an infectious-provocative nursery in the field and greenhouse of the Institute of Rice in compliance with the methodical guidelines in 2003 – 2016. In of the south Ukrainian, Pyricularia oryzea is the most harmful for rice. The article presents the results on forming a trait collection studying rice accessions. It presents the results of 7-year studies (2010 – 2016) on the search for sources for resistance to the pathogen among 190 rice accessions of different eco-geographical origin. In the years with various meteorological conditions and various development of disease, we revealed several sources of resistance to the pathogen. There were 64 disease-resistant accessions (33,7 %). Most of the accessions under investigation were medium-resistant to Pyricularia oryzae (50,5%). In the period of 2003 – 2004 and 2007 – 2009, 58 rice accessions were studied on artificial infection. In the greenhouse, 19 (33,7%) resistant accessions were found. Most of the accessions under investigation were susceptible (46,6%) and medium-resistant to Pyricularia oryzae (20,7 %).\u0000\u0000Conclusions. The trait collection comprising 58 accessions belonging to 13 varieties from 8 foreign countries has been formed. Reference varieties and sources of resistance to disease in combination with a set of economic features were defined. These accessions are of great interest to breeding for valuable agronomic traits as they combine resistance to disease with several economically valuable characteristics. The collection is of great importance for achieving different scientific and breeding objectives. All the valuable material will be transferred for introduction in breeding.","PeriodicalId":306712,"journal":{"name":"Genetičnì resursi roslin (Plant Genetic Resources)","volume":"6 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":"123653523","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}
