    Evaluation of gladiolus (Gladiolus cardinalis Cape) varieties for growth, flower production and quality traits
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2004-07) Lepcha, Boniface; Nautiyal, M.C.
    The present investigation was conducted during 2004 at G.B. Pant University of Agriculture and Technology, Hill Campus, Ranichauri, with 13 gladiolus cultivars. The experiment was laid out in a Randomized Complete Block Design with 4 replications. The parameters pertinent to vegetative growth, flower production, floral traits and quality were studied. Results from the present investigation revealed that significant variation in most of the characters were found among different varieties of gladiolus. Red Majesty showed the earliest sprouting (18.50 days), maximum leaf number (10.50), leaf dry matter (38.91%) and the longest flowering duration (19.25 days). The cultivar Priscilla exhibited the highest sprouting percentage (91.25%) and plant height at spike emergence (62.25 cm). However, White Prosperity attained the longest spike length (87.75 cm), spike girth (1.30 cm), maximum number of floret (19.50), floret diameter (10.20 cm) and vase life of flowers (11.25 days). Observation on cormel production revealed that highest number of cormels was produced by the cultivar Cham Flow (56.50), while maximum size (3.32cm) and weight of cormel (21.33 g) were recorded in Summer Pearl. The correlation study among growth, flower yield and its components indicated that spike length had strong positive association with spike girth, number of floret, weight of floret and vase life of flower. Genotypic and phenotypic coefficient of variations were high for sprouting percent, number of cormels and cormel weight. The magnitude of PCV was in general high indicating the influence of environment. Heritability was high for almost all the characters. While, genetic gain appeared high for sprouting percent, number of cormels, cormel weight and cormel size. On the basis of the salient findings obtained from the present study, it can be concluded that for obtaining higher yield and superior quality of flowers of gladiolus, varieties like Candyman, White Prosperity, Summer Pearl, Red Majesty and Charm Flow should be selected for rain-fed midhill conditions of Uttaranchal. It is also apparent from the study that characters like sprouting percent, cormel weight and cormel size that combined high heritability and genetic gain, should given more emphasis in gladiolus improvement programme.
