Abstract

The paper present the results of investigations for heat-resistance in sun-flower inbred lines by seed heating with further estimation of seedlings' growth parameters. As a main criterion of heat-resistance we used seed germination after heat application, and as the additional one – the length of a rootlet of the seedling/ the obtained data were put in good order on the basis of scoring scales for the division of samples into groups of resistance. The best lines are recom-mended for a further usage in sunflower breeding
