[The genetic interpretation of the electrophoregrams of the helianthin in F1 sunflower seeds].

It has been shown, that in most cases the fertile plants of maternal line and F1 plants of respective hybrid are present among sterile plants of sunflower female lines in crossing plots. As a result, 16 various genotypes of seeds are ascertained in crossing plots at monogenic differences in marker trait. Only two classes are F1 seeds. In such cases specific share of 5 genotype groups may be distinguished by phenotypes of heliantin electrophoregrammes. Seeds of biological admixture may be attributed to the 6th distinguishing type.
