Abstract:
The present investigation was carried out at Experimental Farm, Division of Vegetable Science & Floriculture, Sher-e-Kashmir University of Agricultural Sciences and Technology. Chatha during 2018-19 to study the variability studies in Gladiolus (Gladiolus grandiflorus L.). The experiment was laid out in a Randomized Block Design with three replications. Twenty-five genotypes of gladiolus were evaluated for 21 yield and flowering related traits to study their genetic parameters such as variability, heritability and coefficient of variation, Analysis of variance for all the traits showed significant differences among genotypes for all the flower and yield related traits. Heritability in broad sense varied between 30.80% to 98.60%. High heritability for number of cormels per plant, followed by number of corms per plant, stem diameter, durability of first floret, spike length, leaf area, number of florets per spike, plant height and days taken to spike emergence. Genetic advance was high for spike length followed by rachis length, durability of first floret, leaf area, plant height and days taken to spike emergence.
