Performance of Gladiolus Genotypes for Growth and Flowering under Gangetic Region of Bihar, India

An evaluation experiment on performance of gladiolus genotypes was conducted at Botanical Garden, Bihar Agricultural University, Sabour during 2021-2022 for the identification of suitable genotype for the cultivation in Bihar. Twenty genotypes of gladiolus were evaluated for vegetative, floral and vase life parameters under Gangetic region of Bihar conditions. The best genotypes identified in present investigation based on mean performance were White Prosperity (79.73 cm), Red Majesty (79.27 cm), Nova Lux (73.47 cm) and Rose Supreme (73.40 cm) for spike length. Earliness in flowering was observed in Rose Supreme (83.53 days) which was at par with Punjab Dawn (83.60 days). Genotype Kum Kum responded well for number of spikes per plant (2.73), whereas Pusa Shubham for corms production (3.33). Genotype White Prosperity (30.27 days) and Rose Supreme (28.47 days) were recorded long flowering duration.
