Abstract:
The present experiment was carried out during the period from November'2008 to
October' 2009 to investigate the morphology, market demand. and production of
hybrid seed and % of hybrid seed germination in gladiolus. The experiment
included five gladiolus genotypes. The results indicated the existence of wide
variability among the genotypes on their morphological characters along with yield
and yield attributes. Genotypes varied from 59.63 cm to 92.05 cm and 25.66 cm to
47.30cm in spike length and raehis length, respectively. Number of flower was the
highest in white (14.25) and the lowest in orange (8.40) genotype. Number of
connel and eorrnel weight of the genotypes significantly difThred and ranged from
25.70 to 43.20 and 5.20g to 6.40 g. respectively. The price of gladiolus flower
varied from genotype to genotype and the demand and price of gladiolus flower
also varied in different month of the year, different clays of the week and different
special days of the year. Considering crossing parameters, variation were observed
for length of capsule (cm). breadth of capsule and thousand seed weight (g). Mean
data indicated that all the crosses produced gladiolus true seed i.e. F1 seed. The
number of seeds per capsule ranged from 15.08 to 38.40. The highest number of
seed per capsule was produced by the cross Yellow x Red (38.40) while the lowest
number of seed per capsule was produced by the cross Violet x Red (15.08).
