The object of research - varieties and lines of winter oilseed rape. The purpose of research: to evaluate sort of collection of samples and the newly created source material of winter rape, to get breeding material and on its basis to create high-yield varieties of oil type and synthesize valuable components to create high heterosis hybrids. Research Methods: field (phenological observations), laboratory and measurement and weight (structural analysis of collection and hybrid material, accounting productivity, determination of the chemical composition of seeds), mathematical-statistical (correlation and regression and dispersion analysis, calculation the parameters of adaptability, degree of phenological dominance, true heterosis, combining ability). Established that stable feature is the height of plant, V10,1%. Considerable variability inherent attributes "number of pods from a plant" (V = 31,8%), "the number of seeds from a plant" (32.0%), and the "weight of seeds per plant" (33.2%). Marked a strong positive correlation between individual productivity and the number of seed pods per plant (r = 0,93 ± 0,06) and with a mass of 1000 seeds (r = 0,79 ± 0,13). Are allocated sort samples of 9 with a high ecological plasticity and 4 sort samples with high stability yield seeds. Was held hybridization for 130 combinations, resulting in fruits (pods) formed in 104 combinations whose seeds will be sown to study next year. The high total matching capacity on the basis of the weight of seed plants were characterized by 4 sort samples of Black giant _, Anna and Hypanis, low - Rohan, Visbi and Belana. High values of constants a specific combining ability was found in the object of research - varieties and lines of winter oilseed rape. The purpose of research: to assess the collection of samples and grades the newly created source material of winter rape, to get breeding material and on its basis to create high-yield varieties of oil type and synthesize valuable components to create high heterosis hybrids.

High values of constants a specific combining ability of hybrid populations found: Rohan / Belana, Anna / Rohan, Hypanis / Belana, of Black giant / Anna Hypanis / Visbi. The estimation in the number of 35 hybrid combinations with the participation CMS identified forms. All of them showed fixing sterility. The level of heterosis amounted 10-35%. In the competitive nursery were highlighted 4 numbers that by the yield of seed exceeded the standard for 0.4-0.8 t / ha and were characterized by low content of erucic acid - 0-0,3% and glucosinolates - 5-15 mmol / g. Created and transferred to the state variety trials sort of winter rape Monopolist. Application number 15040026 from 5 March 2015.

Saving a scientific data set occurs in two stages:
1.) Creating a data set
Enter the name of the set, a brief description of the set (annotation), and click the “Create set” button. After that, a draft data set will be automatically created, which you can save for further work with the set. The system will redirect you to the “Data set information” page.
2.) Filling in the data
On the “Data set information” page, you need to fill in all the fields related to the data set and upload the files.
Please note! Each file is uploaded separately. This is done to ensure the stable operation of the system.
Once you have filled in the information about the scientific data set and added the necessary files, you can save the draft or send the data to the system.
Please note! Once the data has been sent, you cannot change it.
Drafts are necessary for storing the data set and editing it before sending.
All accounts on the NRA website go through a standard registration procedure and are verified. However, in order to obtain additional features, such as publishing open reviews of academic texts, verification by affiliation is required.
To obtain the status “verified”, you must change your primary email address to a corporate one, which is tied to a scientific or educational institution.
For example: user@ukrintei.ua, user@nas.gov.ua
After confirming your corporate email address, your account will be automatically verified by affiliation.
If your email address is corporate, but your account does not have a verification mark, you need to write to us at the email address NRAT@ukrintei.ua. After verification, we will add your address to the database, and your account will be verified.
After completing the verification procedure for affiliation, you can change the primary email address to a convenient one for you, without losing your status during the current verification.
You only need to verify for affiliation once.
* We use corporate addresses from the Unified State Database on Education and the State Register of Scientific Institutions Supported by the State
To search for news published on the official website of NRАT in the “News” section, you need to enter one word, several words, or an exact phrase in the search field. Different terms are separated by spaces.
The search is performed everywhere – in the title and the news text.
For a more comprehensive result, it is recommended to use word stems (parts of words without endings).
When using multiple words for the search, they are combined using one of the logical methods described below.
By default, the logical connector “and” is used. In this case, search results will include all news releases that contain the specified words, even if they are located separately from each other and are in different parts of the text.
Example: Search phrase: OECD report. Search result: all news containing the words “report” and “OECD” in the text and in the title, both together and separately.
If a phrase or phrase is enclosed in quotation marks (“), the results will include all publications where this exact phrase or phrase is found.
Example: Search phrase: “OECD report.” Search result: all news containing the exact phrase “OECD report.”
If you know the publication date of the news or are interested in a specific time frame in which they were published on the website, you can select such a date or date range in the additional field that looks like a calendar. The date is entered in the format year-month-day and confirmed by clicking on the corresponding date in the calendar dropdown. You can enter a date or choose one by browsing through the calendar by months and years. By default, the interval starts from the oldest date (2018-01-23) and ends with the current date.
You can also use one or more hashtags, which are located under the search field on the right side of the “News” page.
Please note: The search for academic texts is carried out in a separate search window at the following link https://nrat.ukrintei.ua/searchdb.
