ANALYSIS OF SOME QUALITY COMPONENTS TO FEW AMPHIDIPLOID LINES OF WHEAT

Data presented in this experiment was conducted to evaluate some quality components of 10 amphidiploid lines of wheat comparative to their parental forms in order to identify new desirable genotypes or sources of variability. Two consecutive years (2015-2017) was carried out field trials in South Romania. Results for analyzed characters (protein and starch content, hectoliter mass, humidity, grain hardness and water absorbtion) were registered as average for experimentation period. Standard deviation and the coefficient of variability analysis for the mentioned characters revealed that for protein, there is significant variation. Most of the amphidiploid lines of wheat possessed higher levels of protein or starch comparative with parental forms. Highest protein content recorded E35-A line, while higher values of starch presented E19-A line. Also, higher values for hectoliter mass presented E1-A and E5-A lines while most of them registered same values as parental forms for grain hardness or smaller. As a conclusion, E35-A line combined successfully almost all characters and the present study demonstrated high quality characteristics of the amphidiploid lines of wheat in combination with other agronomic desirable characters.
