Abstract:

The genetic materials was consisted of eleven gladiolus varieties in randomized block design (RBD) with three replications was used. Experiment was conducted at Farm of Department of Horticulture at Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology and Sciences Naini, Prayagraj Uttar Pradesh in Rabi season 2019.Mean square due to treatments revealed that significant differences among the genotypes for all the traits except days taken for emergence of flower spike and days taken to show colour of basal floret. The maximum corms yield per plant obtained was American beauty, White propsparity, her majesty and White friendship. High GCV and PCV were exhibited for number of leaves per plant 30 DAS, number of shoot per plant, number of corm produced per mother corm, corms yield per plant, number of cormels per plant, number of cormels per hectare and number of corms per hectare. Therefore, it is concluded that the characters which showed high GCV, PCV and heritability coupled with genetic advance should be considered for direct selection. Here the number of cormels per plant, number of cormels per hectare, number of shoot per plant, vase life, plant height (cm) 90 DAS and plant height (cm) 60 DAS character under study showed high heritability and genetic advance. Thus one should select these characters for direct selection.
