Abstract: Experiment on Gladiolus was carried out at Sam Higginbottom University of Agriculture,Technology & Sciences,prayagraj and Directorate of Agriculture, Research Field (Floriculture)Jammu for twoyearsduring 2013-2104 to 2014-2015in order to study the genetic variability,heritability,genetic advance,correlation coefficient and stability of eighteen quantitative characters in gladiolus.Twenty genotypes of gladiolus were grown in randomized block design (RBD) with three replications at Allahabad & Jammu. Analysis of variance (ANOVA) revealed that Mean square due to treatments were significant for most of the characters in all the four environments except for number of florets open at first, number of shoots per plant, number of leaves per shoot, number of corms per plant for all the four environments and average weight of cormels per plant in (E2)Jammu. The PCV were higher than GCV for all the character studied for all the environments, indicating high degree of environmental influence.Higher GCV and PCV estimates were found for number of cormels per plant for Prayagraj (E1 and E3) and cormels per plant and corm per plant for Jammu (E2 and E4). Heritability in broad sense was found to be high for mostly characters studied in all the environments.Low heritability recorded for the characters viz; Diameter of cormAllahabad (E1),floret remain open at a time and shoot per plant at Allahabad(E1) Jammu for the characters durability of whole spike (E2 and E4) and florets open at First(E4). Number of cormels per plant showed moderate to high heritability along with high genetic advance showing additive gene effects. All the genotypic correlation coefficientwerehigher than phenotypic correlation coefficients. Days to first floret colour showing was positively correlated with days to first floret opening in most of the environments. Days to 50% heading,days to first floret colour showing,days to first floret opening showed significant positive correlation with days to first floret colour showing in most of the environments shoot/plant showed significant positive correlation with corms/plant in most of the environments and rachis length showed significant positive correlation with plant height(cm). Therefore,selection for former characters will be of great significance in a crop like gladiolus,since itincreasesthe aesthetic value of the cultivars. Considering all the floral characters cutivarsArkaAmar, Charm Flow, Green Bay, Poppy Tears, Red Ginger,Punab Dawn,Darsan, Red Mejestry and Legent were found suitable for commercial cultivation under northern Indian(Prayagraj&Jammu).The promising cultivars for corm and cormels production are Poppy Tears, Candy Man, Hunting Song and Jester.
