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. The magnitude of correlation coefficient at genotypic level was found higher than the corresponding correlation at phenotypic level. Number of florets per spike had a positive and highly significant correlation both at genotypic and phenotypic levels with spike length (0.923, 0.956), rachis length (0.769, 0.956), weight of corm per plant (0.383, 0.299), number of cormels per plant (0.327, 0.3100) and diameter of corms (0.326, 0.251) respectively.
