Ethyl methanesulfonate induced variation in qualitative and quantitative characters of roselle (Hibiscus sabdariffa L.) (Malvaceae)


, : Ethyl methanesulfonate induced variation in qualitative and quantitative characters of roselle (Hibiscus sabdariffa L.) (Malvaceae). Revista Brasileira de Genetica 16(2): 381-391

Seeds of roselle cultivars Jamaican Red (JR) and Jamaican Green (JG) were presoaked for four hours in distilled water and treated with 0.0, 0.4, 0.8 and 1.2% ethyl methanesulfonate (EMS) for 8 h and 0.0, 0.6 and 0.8% EMS for 6 h, respectively, in order to induce variation in qualitative and quantitative characters. In the M1 generation, germination and survival percentage of both cultivars decreased, whereas semi-sterility increased with the increase in EMS concentration.
