Abstract
Introduction of sunflower varieties and hyhrids is the best protection against the sunflower moth. Sunflower resistance to the pest depends on the presence of the phytomelanin layer in the pericarp. An analysis of 23 wild sunflower species with a saturated solution of bichromate (K2CrO7) and sulphuric acid (H2SO4) has shown that the perennial species tested have a thicker average phytomelanin layer that the annual species. Differences have also been found between the species as well as between populations of individual species. Of the 84 populations tested, only 6 of these had the phytomelanin layer 100% of the achenes tested.
