The trial was carried out ten diverse genotypes of gerbera for different yield attributing traits under naturally ventilated polyhouse conditions. The experiment was laid out in randomized block design to determine association between different quantitative traits during 2015-2016. The magnitude of genotypic correlation was higher than their corresponding phenotypic correlation for most of the traits, indicating a strong inherent linkage between various traits under study. The results indicated that the plant height, leaf length, leaf breadth, number of leaves, leaf area, leaf area index, number of suckers per plant, chlorophyll content, flower diameter, flower stalk diameter, length of the flower stalk, disc diameter, duration of flowering, field life, fresh weight of flower and dry weight of flower showed positive significant correlation with number of flowers per plant at both genotypic and phenotypic level. Negative correlation was observed for days to first-flower opening and days for 50% flowering with number of flowers per plant. Number of suckers per plant and flower diameter were positively and significantly correlated with plant height, leaf area, leaf area index, chlorophyll content, flower stalk diameter, length of the flower stalk, disc diameter, duration of flowering, field life, fresh weight and dry weight of flower. The results revealed that flower diameter, number of flowers and suckers per plant were important yield characters. Hence, these characters may be considered as selection indices in gerbera breeding programme.
