Abstract: The present investigation on “Genetic variability studies in Gladiolus [Gladiolus grandiflora (L.)]” was carried out during the year 2018-19. The experiment was conducted at Departmental research field, Department of Horticulture, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj (U.P.) during 2018-19.The experiment was conducted in Randomised Block Design (RBD),with 10 treatments representing the cultivars of gladiolus. The varieties are V₁: American Beauty, V₂: Souvenir, V₃: Ecohonder, V₄: Little Prince, V₅: Her Majesty, V₆: Candymon Dark Vermilion, V₇: Thumbelina Pure White, V₈: Summer Sunshine, V₉: Chipper White, V10: Orange. The genotypes Little prince followed by Her Majesty, Orange, Ecohonder produced higher spikes yield per plot. the high magnitude of heritability (in broad sense) coupled with high genetic gain was observed for most of traits exhibiting additive genetic effect Highest GCV and PCV were corded for spike yield per plot (86.73, 86.74 respectively), high GCV and PCV for days taken for sprouting of corms (15.57, 19.64 respectively).
