Screening perennial Helianthus species for powdery mildew
(Paris : International Sunflower Association, 2012)
Powdery mildew (Erysiphe cichoracearum) has been reported as a potential constraint for sunflower growing in regions with warm climate. Severity of disease varies depending on the sunflower genotype. Aim of this research ...
Sunflower breeding for production stability - Example of NS hybrids
(Paris : International Sunflower Association, 2018)
Sunflower breeding process involves the selection of hybrids which have the tendency to maximize yield potential and its stability in different growing regions. Perspective genotypes are usually evaluated in different ...
