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. Analysis of variance for all the traits showed significant differences among genotypes for all the flower and yield related traits. High range in mean performance has been observed for traits, viz. plant height (79.13 cm - 125.10 cm), no. of leaves (5.00 - 8.00), leaf area (61.00 cm² - 114.47 cm²), number of florets per spike (8.60 to 14.73), spike length (59.13 cm -105.10 cm), Rachis length (33.63 cm - 71.90 cm), durability of first floret (4.60 - 8.63 days), flower duration (12.07-17.83 days), stem diameter (5.50 cm to 15.70 cm), floret size (4.36 cm to 7.26 cm), vase life (7.10 to 9.96 days), chlorophyll content (41.90 - 58.59), number of corms (1.66 - 3.66), weight of corm per plant (11.63 g - 36.63 g), diameter of corm (3.26 cm - 5.43 cm), numbers of cormels per plant (11.20 - 22.80).
