In order to investigate the effect of planting date on local landraces and varieties of Hibiscus sabdariffa L., a factorial experiment was conducted in a randomized complete block design in Dalgan during the 2019. Planting date as the first factor in five levels (March 6, April 4, May 5, June 5 and July 01) and genotypes and cultivars as the second factor in ten levels (Jiroft, Delgan, Bampour, Iranshahr, Nikshahr, South Rudbar, Saravan and Qale Ganj and two commercial varieties HA and HS-24) were considered. The examined traits included stem diameter, fresh and dry boll weight, sepal dry weight, anthocyanin, and etc. Results showed that the effect of planting date on all studied traits was significant at 1% level. The effect of genotype was significant on the number of days to budding, leaf number, days to 50% flowering and sepal dry weight per plant. The interaction of planting date and genotypes on sepal dry weight, anthocyanin content, seed rate and biological yield were significant at 1% level. The highest sepal dry weight per plant was obtained at May 15 planting date. Also, the local landrace of Dalgan and Saravan had the highest and the lowest amount of sepal dry wieght, respectively. Fresh and dry weight of boll, number of leaves, stem diameter, plant seed and anthocyanin content were significantly correlated with sepal dry weight. As a result, May 15 planting date and local landrace of Dalgan showed higher yield.
