Purpose. Improvement of a range of strawberry varieties based on comprehensive study and introduction of new Ukrainian and West European cultivars. Methods. Cultivars and elite forms were studied using the methods of primary variety studying and state variety testing at three-year strawberry plantations of the Institute of Horticulture of the National Academy of Sciences of Ukraine (the city of Kyiv) and its variety testing stations. Results. It was found that more frequent spring and summer droughts as well as black frosts in winter adversely affected the strawberry productivity. The best varieties were selected among new ones for the complex of traits, they included ‘Elegance’ from the Great Britain, ‘Gercules’ from Ukraine (both are dessert grapes), ‘Elsanta’ from Holland (for universal use), ‘Alba’ from Italia (as raw material). The highly adaptive and productive ‘Istochnik’ and ‘Festyvalna romashka’ varieties (as raw material) are recommended for the north regions. Conclusions. In the context of profound climatic change, high-profitable cultivation of mid-ripening varieties and a strawberry as such in the Northern Forest-Steppe zone is expedient under controlled conditions – in high film tunnels, in hot-houses and under perennial irrigation that already has become the European tendency.

Evaluation of winter wheat varieties and promising lines of Myronovka’s intitute breeding in terms of grain quality Полный текст
Ковалишина, Kovalyshyna, H. M., Г. М. | Топко, Topko, R. I., Р. І.
Purpose. To evaluate the varieties: ‘MIP Assol’, ‘Balada Myronivska’, ‘Hratsiia Myronivska’, ‘MIP Yuvileina’, ‘MIP Lada’, ‘MIP Dniprianka’ and the standard variety ‘Podolianka’ and promising breeding lines: ‘Erythrospermum 55023’, ‘Lutescens 22198’, ‘Lutescens 37519’, ‘Lutescens 60049’, ‘Lutescens 60107’ winter wheat of the Mironovka`s breeding according to grain quality indicators.Methods. The research was conducted during the 2019–2021 in the breeding crop rotation of the winter wheat breeding laboratory of the V. M. Remeslo Myronivka Institute of Wheat, NAАS of Ukraine. The main method of research was laboratory and field, supplemented by analytical studies, measurements, calculations and observations.Results. The following breeding lines were the best in terms of protein content during the first sowing period: ‘Erythrospermum 55023’ (11.9%), ‘Lutescens 55198’ (12.8%), ‘Lutescens 37519’ (11.7%) and ‘Lutescens 60107’ (10.7%). During the second sowing period, the best varieties and breeding lines turned out to be ‘Hratsiia Myronivska’ (11.4%), ‘MIP Dniprianka’ (12.3%), ‘Erythrospermum 55023’ (12.3 %), ‘Lutescens 55198’ (11.4%), ‘Lutescens 37519’ (12.3%) and ‘Lutescens 60049’ (12.8%). According to the grain vitrification index during the first sowing period, the following can be distinguished: ‘Balada Myronivska’ (86.7%), ‘MIP Lada’ (89.3%), ‘MIP Dniprianka’ (87.3%), ‘Erythrospermum 55023’ (86.3 %), ‘Lutescens 55198’ (94.3 %) and ‘Lutescens 37519’ (91.0 %). During the second sowing period, these were ‘Balada Myronivska’ (86.7%), ‘Hratsiia Myronivska’ (79.3%), ‘MIP Lada’ (85.0%), ‘MIP Dniprianka’ (81.7%) and breeding lines ‘Lutescens 55198’ (80.7%) and ‘Lutescens 60049’ (81.3%). According to the content of raw gluten, the variety ‘Hratsiia Myronivska’ (26.2%) was selected. For all studied breeding lines, the value of the crude gluten content indicator varied from 26.0% to 29.9%. During the second sowing period, a higher percentage of raw gluten content was noted in the varieties ‘Hratsiia Myronivska’ (29.9%) and ‘MIP Dniprianka’ (27.4%) and selection lines – ‘Erythrospermum 55023’ (28.4%), ‘Lutescens 55198’ (27.4%), ‘Lutescens 37519’ (27.1%) and ‘Lutescens 60049’ (29.1%).Conclusions. During the three years of observations, the weather conditions differed in the amount of precipitation and the sum of active temperatures both during the growing season and during the period of flowering and maturation, which significantly affected the results of the analysis of grain quality indicators of winter wheat varieties and promising lines. Having analyzed the obtained results, it is possible to single out the varieties ‘Hratsiia Myronivska’ and ‘MIP Dniprianka’, as well as the breeding lines: ‘Erythrospermum 55023’, ‘Lutescens 55198’, ‘Lutescens 37519’ and ‘Lutescens 60049’, which exceeded the standard variety ‘Podolianka’ and the average experimental values for such basic indicators as protein content, gluten content, vitreousness and 1000-seed weight. | Мета.

Dawson, Terence P. | Perryman, Anita H. | Osborne, Tom M.
The United Nations Food and Agriculture Organization (FAO) estimate that nearly 900 million people on the planet are suffering from chronic hunger. This state of affairs led to the making of the United Nations Millennium Development Goals in 2000, having the first goal to “Eradicate extreme poverty and hunger” with a target to halve the proportion of people who suffer from hunger. However, projections of a rapidly growing population, coupled with global climate change, is expected to have significant negative impacts on food security. To investigate this prospect, a modelling framework was developed under the QUEST-GSI programme, which we have termed FEEDME (Food Estimation and Export for Diet and Malnutrition Evaluation). The model uses country-level Food Balance Sheets (FBS) to determine mean calories on a per-capita basis, and a coefficient of variation to account for the degree of inequality in access to food across national populations. Calorific values of individual food items in the FBS of countries were modified by revision of crop yields and population changes under the SRES A1B climate change and social-economic scenarios respectively for 2050, 2085 and 2100. Under a no-climate change scenario, based upon projected changes in population and agricultural land use only, results show that 31 % (2.5 billion people by 2050) of the global population is at risk of undernourishment if no adaptation or agricultural innovation is made in the intervening years. An additional 21 % (1.7 billion people) is at risk of undernourishment by 2050 when climate change is taken into account. However, the model does not account for future trends in technology, improved crop varieties or agricultural trade interventions, although it is clear that all of these adaptation strategies will need to be embraced on a global scale if society is to ensure adequate food supplies for a projected global population of greater than 9 billion people.
