Abstrakt: Gladiolus, is one of the most important cut flowers and known as the Queen of bulbous flower. The aim of this research was to produce superior genotypes through self- pollination of Gladiolus grandiflorus cv. Amsterdam, the experimental was randomized complete block design (RCBD). This research was conducted in Ornamental Plants Research Center in 2015 to 2018 (OPRC). Analysis of variance among genotypes showed that significant differences in all traits were conducted (except for cormlet weight). The oprc46 genotype was superior in the width and length of floret and diameter of bud. The oprc45 genotype was superior in terms of vase life, weight of corm, yield of corm and cormlet per plant. The highest number of cormlet (64n) was produced by oprc415 genotypes. The highest number of traits in parent was obtained for number of florets, length of peduncle, diameter of stem, length of spike and diameter of cormlet. Correlation coefficients show that the most positive and significant correlation between the yield of corm and cormlet per plant and weight of corm (r=+0.98). The results showed that the flower color in genotypes tendency to white. In most genotypes and parents, arrangement of flowers was one row and shape in front view was star-shaped. The results of grouping showed that classified into three groups and the parent group was separated another genotype. The results showed that major of the diversity in the traits was due to genetic factors and the effect of the environment on these traits was less. [ABSTRACT FROM AUTHOR]
