Use of electrophoretic spectra of reserve seed proteins to improve typicalness of sunflower parental lines

Abstract

This paper shows the possibility of the efficient individual plant selection from sunflower parentallines by allelic variants of components of electrophoretic spectra of reserve proteins. The plants have been evaluated and selected by electrophoretic spectra of reserve proteins and, at the same time, evaluated by morphological features, which has ensured increased genetic homogeneity of parentalline ZL95A. Moreover, the genetic purity of sterile line alternative Ast, determined by ground control, is 98.4% and the genetic purity of line sterility fixer Af is 98.5%. The typicalness of the sterile alternative and the sterility fixer defined by allelic variants of components of electrophoretic spectra of reserve proteins is 100%.
