摘　　要：The sunflower has the potential to be a highly competitive crop owing to its diversity market and the valuable oil it produces.Nevertheless,the amount of sunflower seed oil-a key factor for the crushing industry-is affected by genotype and environment,which sometimes is difficult to predict.The paper analyzes the theoretical principles of sunflower growth in Ukraine,highlights the current trends in the sowing of this crop,the influence of climatic factors of the environment on the prospects of the oilseed sunflower yield.The results of the research are presented for 3 years(2014-2016),during the authors conducted a grain quality observatory at the regional level,taking into account the climatic conditions of sunflower growth in different natural zones of Ukraine(from 45
to 51
north latitude and from 22
to 37
east longitude).Additionally,the research includes the coefficient of significance of the deviation from long-term climatic indicators,which makes it possible to forecast sunflower yield in the future.The analyzed data was obtained from the commercial fields with a minimum area of 40 ha in all Ukrainian regions except Crimea peninsula,Donetsk and Luhansk regions.The results obtained in research show the great diversity of oil content index as per both latitude and longitude meaning.If we consider the entire country,this survey shows that the seed oil content can change dramatically from year to year:e.g.47.5%in one year versus 45.7%in another year.Regionally,these changes have a completely different dynamic with a gradual decrease in seed oil content in the southern part of the country.The main goal of the research was to identify the best sunflower growing areas in Ukraine according to the oil content index.
