Анализ биотипного состава староместных сортов мягкой пшеницы из коллекции ВИР в процессе хранения и репродукции

Аннотация

A high dissimilarity of ancient local wheat varieties Krymok and Banatok in protein character has been shown by electrophoretical analysis of storage grain protein - gliadin: each sample is characterized by the availability of two biotypes and more, which are marked by gliadin spectrum. 6 Banatok samples were resown during 3 years. There were substantial changes in their biotype composition. Field germination rate of various "gliadin biotypes" has been determined in 7 samples after storage in natural conditions. Biotypes of a sample were demonstrated to differ markedly by the rate of decrease of vitality of their seeds in storage.
