Evaluation of Zinnia (Zinnia elegans L.) genotypes under West Garo Hills District, Meghalaya was carried out at the experimental farm Department of Horticulture, NEHU, Chandmari, Tura Campus, during 2016-2017 to identify the suitable variety for successful cultivation and flower production under prevailing agro-climatic conditions. Eleven varieties namely, Zinnia Royal Purple, Zinnia Double Mixed, Zinnia Illuminated Deep Rose, Zinnia Dreamland Takii, F1 Tall Zinnia Red, Zinnia Orange King, Zinnia Double Orange, F1Elegans Zinnia Pink, Zinnia Dahlia Flowered, Zinnia Polar Bear White and Zinnia Cherry Queen were selected for their evaluation. The experiment was laid out in Completely Randomized Design (CRD) with four replications. Uniform package of practices were followed throughout the experiment to grow a healthy crop. Highest plant height in cultivar F1Elegans Zinnia Pink (136.25 cm), number of leaves in cv. Zinnia Polar Bear White (121.00), E-W plant spread in cv. Zinnia Cherry Queen (50.59 cm), stem diameter in cv. Zinnia Orange King (12.18 cm) were noticed. However, leaf length (11.00 cm) and internodal length (10.55 cm) in cv. Zinnia Double Mixed, number of branches (13.50) and N-S plant spread (43.75 cm) in cv. Zinnia Double Orange, leaf breadth (5.25 cm) and leaf area (37.67 cm2) in cv. Zinnia Royal Purple were observed. Whereas, minimum days to bud initiation (36.00 days) in cv. Zinnia Dreamland Takii, maximum flower duration (57.25 days) in cv. Zinnia Double Orange was obtained. Highest ray floret length (2.95 cm) and width (1.07 cm) in cv. F1 Tall Zinnia Red, number of ray floret per head (57.00), fresh weight of flower per head (1.77 g), dry weight of flower per head (0.91 g) and number of flower head per plant (7.75) in cv. Zinnia Dreamland Takii were found. While, maximum number of flowers per spray per plant (4.15) and vase life of zinnia flowers under tap water (8.14 days) was recorded with cv. Zinnia Cherry Queen followed by cv. Zinnia Dreamland Takii (6.00 days) were recorded.
