Band composition of electrophoretic spectra of storage proteins in interspecific pea hybrids

Electrophoretic spectra of storage proteins in parental plants and interspecific F 1 and F 2 hybrids Pisum sativum × Pisum fulvum have been studied. Correspondence between the polymorphism levels of protein components among the species and within the species P. sativum was established. Accessions of P. fulvum I609881 and I609885 manifested low polymorphism. Storage proteins of both parents were observed in spectra of F 1 hybrids. F 2 hybrids segregated at a limited set of bands. Accession I609881 of P. fulvum is characterized by unique band 7, which was inherited in F 1 .
