Abstract:

    Gladiolus is one of the Taiwan major cut flowers, the planting area is about 700 to 800 ha per year, and most of the cultivars are imported. For the purpose of one’s own variety, ARI proceeded with the breeding works of gladiolus. The new gladiolus (Gladiolus hybridus Hort.) variety of “Tainung No. 2”, E6 line, selected from self-hybridized offspring of “Blaze” commercial variety imported from USA in 1985. After many years of tests in lines observation, comparison and field trials, the E6 line had excellent performance in horticultural characteristics and named as “Tainung No.2” by the Council of Agriculture, Executive Yuan on April 23, 2004. “Tainung No.2” categories to a middle-late variety, in summer and autumn, it needs 68 to 88 days and 74 to 91 days to produce cut flower, respectively. The number of florets is about 12-15 and the length of spike is about 110-120cm which can fit in with the standard of exported flowers. Red color flower, 8-11cm in diameter, had a shelf life of 7-9 days. The fresh weight of corm increasing is about 3-5 fold with an average number of harvested cormel, greater than 0.5cm, about 200 per corm. During the period of evaluation, under normal cultivating procedure, there were not sever symptoms of disease (Pseudomonas marginata (McCull.) Stapp. and Botrytis gladiolorum Timmermans) observed. “Tainung No.2” would cultivate well at the major gladiolus production areas in Taiwan (Ho-Li, Taichung county and Bei-Do, Changhua county).
