Abstract

Eighteen hybrids and two checks viz., LSFH-35 and LSFH-171 of sunflower were evaluated for their
morphological and biochemical traits imparting tolerance/resistance to powdery mildew during rabi, 2018-19. A Field experiment in Randomized Block Design with three replications was carried out. The results revealed that sunflower hybrids viz., LSFH-2026, LSFH-216, LSFH-3008 and LSFH-1225 exhibited moderately resistant to moderately susceptible reaction to powdery mildew. The character association studies of host resistance indicated that powdery mildew had positive and significant correlation with the amount of reducing sugar and stomatal frequency and size while negatively correlated with trichome density, chlorophyll, total phenols and total sugars.
