The present investigation was conducted at Field Experimentation Centre, Department of Horticulture, Naini Agriculture Institute, SHUATS, Allahabad during 2013-2014 to assess the variability, heritability, and genetic advance of 20 genotypes for eighteen quantitative characters in gladiolus. Phenotypic coefficients of variation (PCV) and genotypic coefficients of variation (GCV) for all the characters under study ranged from 4.73 to 56.94 percent and 3.84 to 56.64 percent respectively. PCV was higher than the respective GCV for all the characters under study indicating high degree of environmental influence. The heritability of different quantitative characters varied from 32.00 (diameter of corms cm) to 99.1 percent (cormels per plant). The high heritability coupled with high genetic advance (percentage of mean) for cormels/plant (99.1 and 116.29 respectively) advocated high genetic progress for this character.

Keywords: Heritability, Genetic advance, PCV, GCV and Gladiolus.
