GENETIC VARIABILITY IN GLADIOLUS
Gladiolus or sword lily is commercially significant bulbous ornamental crop which is
grown either as cut flower or garden display. Improvement in gladiolus required genetic
variability, its heritability and genetic progress. Also, knowledge of association between
yield and its component traits themselves can improve the efficiency of selection. The
present study was undertaken to observe the phenotypic variability into its heritable and
non-heritable components with suitable genetic parameters viz., phenotypic and
genotypic coefficient of variation, heritability, genetic advance. Fifteen elite genotypes of
gladiolus were collected from various places and conducted experiment at research
farm, Department of Horticulture, Allahabad Agricultural Institute-Deemed University,
Allahabad during 2005 in Randomized Block Design with three replications. High
genotypic coefficients of variation (GCV) and phenotypic coefficient of variation (PCV)
estimates were found for number of cormels per corm. High heritability with high genetic
advance was observed for number of cormels per corm, days for spike emergence and
spike weight. Number of florets per spike was significantly and positively correlated with
number of shoots per corm and duration of flowering. Spike length and diameter of corm
was significantly and positively correlated with spike weight but negatively correlated
with duration of flowering.
