This paper shows the efficiency of the individual selection of plants of the maternal line of sunflower belonging to the type ZL95 on electrophoretic spectra of storage proteins of seeds with a simultaneous assessment of morphological traits for the increase and maintenance of genetic uniformity. On the localization of components of polypeptides their mobility and intensity were installed and identified the allelic options of the electrophoretic spectra: Hel-1 Hel-2 Hel-3 Hel-4 and Hel-6 . By the method of individual selection of plants on the set protein spectra with simultaneous control on morphological traits increased the genetic purity of male analogue line ZL95 from 44.0 to 98.4% fixer of sterility from 47.0 to 98.5% and the assessment on protein spectra 100.0% at both analogues of the line.
