On- farm trail was conducted in Longleng district of Nagaland during 2016-17 to compare the phonological development and production potential of four varieties of gerbera viz. Silvester, Stanza, Rosalin and Brilliance at farmers field under naturally ventilated polyhouse conditionin Longleng District of Nagaland. Result revealed that Rosalin recorded maximum leaf length (49.68 cm), plant spread (57.82 cm), flower diameter (12.04 cm), diameter of trans floret (7.52 cm), diameter of disc floret (3.4 cm), Peduncle diameter (0.8 cm), length of ray floret (5.44 cm), width of ray floret (1.12 cm), whereas Stanza recorded maximum leaf breadth (19.76 cm), no. of ray floret (73.4 nos.), vase life (13.2 days), Silvester recorded maximum in plant height (52.04 cm), no. of leaf/plant (19.6 nos.) and no. of suckers /plant (2.2 nos.), no. of flowers/plant (8.4 nos.) and Brilliance recorded maximum Peduncle length (70.96 cm). Vase life of flower was recorded significantly higherin Stanza (13.2 days) as compared to other cultivars and minimum with Brilliance (10.8 days). Rosalin and Stanza appears to be the best cultivars under Longleng climatic condition as compared to Silvester and Brilliance in terms of vegetative growth and flowering quality characters.
