Abstract:

A study was conducted on genetic variability, heritability and genetic advance among various characters influencing the flower yield of twelve different genotypes of Gladiolus. The field experiment was carried out in Randomized Block Design during rabi season of 2017-18 under semi-arid climatic condition at Experimental block of Department of Horticulture, College of Agriculture, University of Agricultural Sciences, Raichur. The data was observed from five randomly selected competitive plants from each replication for eighteen quantitative traits. The analysis of variance revealed significance differences among the different genotypes. The phenotypic coefficient of variation (PCV) was higher than genotypic coefficient of variation (GCV) for all characters indicating the influence of environment on these characters. High phenotypic and genotypic coefficients of variation was observed for weight of cormels, number of corms produced, number of florets, day to 50% flowering and number of leaves at maturity. The estimates of heritability varied from 21.25 to 91.75 % for different characters under study. It was found high for all the traits except number of corms produced and leaf width at maturity. High heritability estimates coupled with high genetic advance over mean was observed for all the traits except leaf width at maturity, plant height at maturity and number of days for lowest floret to open.
