Study of fatty and protein composition in 8 wheat genotypes

Due to protein pattern and fatty acid composition in 8 wheat genotypes, quantitative and qualitative analysis of fatty acids and proteins was performed. Then, the relationship between protein and fatty acid ratio of the above genotypes was investigated. SDS-PAG and A-PAG were used to determine the protein pattern. The analysis of fatty acids was performed by the machine GC. The major fatty acids were oleic-palmitic-stearic-linolenic or oleic-stearic-palmitic-linolenic genotypes. Between the glyadine strips, the barrel 35 showed a significant negative correlation with DHE-fatty acids at the level of 0.05 (corelation = -0.732) and fatty acid (14C) at the level of 0.01 (corelation = -0.850). Protein bands of 44.5, 47 and 72, respectively, showed a significant negative relationship with fatty acids 16C:, 14C: and 18C: (corelation = -0.756) respectively. Also, Arachedonat fatty acid had a significant positive correlation with Glu-D1 gene , 12 + 2 protein bands and Protein 1 protein from Glu-A1 gene at 0.01 level and with a protein of 9+ 7 protein from the Glu-B1 gene site significant negative correlation was found between 0.05 and 0 8 + 6 and 21 from Glu-B1 gene site with fatty acid: 14 C: a significant negative correlation was observed in the level of 0.05.
