Вплив батьківських форм на стійкість до збудника фомопсису гібридів соняшнику

Abstract

There are summarized the data of the 2-year (2003-2004) studies on the experimental hybrid combinations of sunflower as to their resistance to phomopsis under field conditions. By means of methods and statistic modelling there has been shown a relationship of the degree of damage of the hybrids and their parental lines. There have been identified some parental forms – lines being different as to their resistance to a casual agent of phomopsis providing hybrids with a high and medium degree of resistance
