Abstract

Gladiolus is an important cut flower commercially grown in Sikkim for local market and for export to the other part of the country. However lack of scientific studies and crop improvement program seems depriving for proper utilization of the available varieties for quality production. The aim of the study was to find out the suitability of ten Gladiolus varieties for cultivation under Sikkim conditions in terms of growth and flowering characters for cut flower production.. Among the selected varieties, Wed in Bouquets obtained maximum plant height (59.09 cm) but maximum spike length (117.56 cm), spike weight (107.94 g) and maximum vase life (14.2 days) were obtained in Puppy Tears, whereas maximum numbers of florets were produced by Wed in Bouquets (13.33). Priscilla produced highest number of cormlets (63.87) among all the selected varieties. The variability and both PCV and GCV were highest for number of parameters among the different varieties. Heritability estimates were high among
