Investigation on protein content and amino acid composition in the kernels of some sunflower lines

Abstract

SUMMARY This study took into account the protein content in the kernel of ten lines derived from interspecific hybrids Helianthus annuus (line 2607) × Helianthus resinosus and Helianthus annuus (line 2607) × Helianthus salicifolius. The amino acid composition of storage protein was also studied. The protein in the new lines exceeded the protein in the parental forms with up to 10.6%. The essential amino acids lysine, valine, threonine and phenylalanine had higher amounts. With regard to sulfur-containing amino acids (cystine and methionine), the new lines had lower content than the line 2607. From the nonessential amino acids, mainly asparagine and glycine exceeded the parental lines.
