Abstract:
The experiment on “Performance of dahlia (Dahlia variabilis L.) genotypes for growth, disease and pest incidence” was carried out at the Department of Floriculture and Landscape Architecture, College of Horticulture, Sirsi, University of Horticultural Sciences, Bagalkot, Karnataka. Among 35 genotypes, genotype HUBD-26 recorded highest plant height (116.69 cm), plant spread (43.93 cm), leaf area index (3.63), stem girth (12.70 mm) and chlorophyll (54.19). Whereas, the genotypes like HUBD-6, HUBD-11, HUBD-17, HUBD-23, HUBD-26 and HUBD-27 were showed no incidence of fusarium wilt and powdery mildew. Regarding aphids and mites, there was no incidence was observed in the genotypes HUBD-17, HUBD-23, HUBD-26 and HUBD-27.
