| Summary: | Gladiolus is an important floricultural and nursery crop used for gardening and floral design. The lengthy, linear stems with large, brightly colored flowers make it a long-term favorite of floral designers. Vase life ranges from 6−10+ d, making this crop a mainstay in the floral industry. The objective of this research was to test a sample of 11 advanced cut flower selections and two cultivars with varying ancestry, plant stature, and floral traits to establish a norm for future breeding and selection criteria for development of a cut flower crop ideotype. Genotypes were tested in field production trials to establish their cut stem length, visible bud date, flowering date, duration of flowering, plant height and width, number of leaves, flower petal type, flower color and petal markings. Flower stems were harvested at stage 2 and then stored at 3−5 °C. Postharvest vase solution treatments were deionized, distilled water and FloraLife Crystal Clear Flower Food 300® floral preservative for 9 d, recording 18 traits related to the inflorescence, water uptake, pH changes, dry matter, flower opening/closure, and salability. In the production trials, flowering week and plant height were the only phenotypic traits with significance. Genotypes were significantly different for nearly all traits examined whereas treatments or their interactions were less so, providing selection potential for future crop improvements. Many traits were significantly correlated, which will provide for greater efficiency and selection potential. Future research will focus on heritability of these traits to provide a foundation of knowledge to create a gladiolus cut flower crop ideotype. |
