Abstract

Genetic variability studies in Gladiolus was carried out among 22 diverse genotypes of gladiolus for 20 characters at two locations -Baraut (Meerut) & Jammu (J&K) during 1998-99 and 1999-2000. The phenotypic coefficient of variation (PCV) were higher than genotypic coefficient of variation (GCV) for all the characters studied, indicating thereby high degree of environment influences higher GCV and PCV estimates were found for number of cormels produced per plant and average weight of cormels per plant Hertability estimates were high (>80%) for days to 50% heading, first floret col. showing and complete opening of first floret Whereas number of cormels per plant, Average weight of cormels per plant and propagation coefficient showed moderate to high hertability along with genetic advance as percentage of mean showing additive gene effects.
