Esterase 1 and Hordein C allelic and genotypic frequencies in CC XXXI, a male sterile barley population

Abstract

Seeds from the 5th, 6th, 12th and 18th generation of enforced outcrossing in CCXXXXI-B, a barley (Hordeum vulgare L.) population containing genetic male sterility, were assayed for genotypic distribution of Est 1 and Hor C alleles. The result suggest that natural selection was effective in altering allelic frequencies at both loci and that genotypic frequencies were often different from what would be expected if allelic frequencies solely determined genotypic frequencies. Departures of actual from expected genotypic frequencies occurred in that shifts in allelic frequencies were detected.
