The experiment included five gladiolus genotypes. Data were collected from different wholesalers and farmers. The results indicated that the existence of wide variability among the genotypes on their market demand, supply and price of different genotypes of gladiolus flower. These indicators were varied among different month of the year, different days of the week and different special days of the year.

The average highest price of gladiolus flower was observed in August (Tk. 11.40) and the lowest price was observed in March (Tk. 4.90). The highest and lowest price of different genotypes of gladiolus flower was ranged from Tk. 2.00 to Tk. 16.00 stick-1. The white genotype had the highest price Tk. 16.00 stick-1 while the orange genotype had the lowest price Tk. 2.00 stick-1. There was significant positive correlation between demand and supply (0.96). The price was negatively correlated with supply (-0.94).
