The present investigation was carried out at department of Horticulture (Floriculture and Landscaping), BAU, Sabour during 2022-23 to evaluate thirteen genotypes of gladiolus under Bihar conditions in Randomized Block Design (RBD) with three replications. The experimental findings revealed that there were significant differences among all genotypes for various growth, floral and corm attributes. Based on their correlation coefficient, spike length (0.556, 0.588), rachis length (0.516, 0.557), floret size (0.415, 0.457), spike vase life (0.412. 0.496), average fresh weight of spike (0.477, 0.494) and spike yield per plot (0.492, 0.529) recorded highly significant and positive correlation with spike yield per plant, whereas plant height (0.310, 0.328) and corm diameter (0.322, 0.345) had significant positive correlation with number of spikes per plant at phenotypic and genotypic level, respectively.
