The present investigation was carried out at Research Farm of the ICAR-Indian Agricultural Research Institute, Regional Station, Katrain (HP), India with 12 gladiolus hybrids along with two check varieties to study their performance under ecological conditions of Kullu Valley of Himachal Pradesh. The mean performance of gladiolus hybrids in terms of vegetative and flower characters studied revealed that maximum plant height (163.07 cm), spike length (107.10 cm), internodal length (6.10 cm) and width of leaf (4.78 cm) recorded by Sunayana open seedling. One open pollinated seedlings each of Suchitra and Sunayana and one hybrid Arka Kesar × Australian Fair were found to be earliest. More number of florets as 19.67 and 18.50 were recorded in Suchitra × Melody hybrid and Peter Pears open pollinated seedling, respectively. The widest diameter of flower (13.41 cm) was recorded in hybrid Archana × Arka Kesar. The maximum length of leaf (52.20 cm) was registered in Suchitra open seedling. Urmi Open seedling and Suchitra x Melody hybrids produced greater number of corms per plant (2.67). However, Suchitra open seedling had more number of cormels (26.33) per plant. Maximum corm size (57.02 mm) was recorded in Archana × Arka Kesar hybrid. Based on the results, it was concluded that inter-varietal hybridization is an effective way to contribute to the phenotypic variations of Gladiolus, which can be used for breeding purposes, and release new cultivars.
