Ethyl Methane Sulfonate (EMS) Effect on Mutagenesis in Balinese Red Rice (Oryza sativa cv. Barak Cenana)

“Barak Cenana” is one of the local red rice (Oryza sativa) with high economic value due to its nutrient content. Some agronomic characters such as tall shoot, low number tiller, and late harvesting are drawbacks improving production. Ethyl Methyl Sulphonate (EMS) a chemical mutagen widely used improve by mutation breeding. The present research aims investigate EMS concentration suitable induce in Barak Cenana observe mutagenesis effect on some Cenana. For those purposes, mature seeds were treated various concentrations (0.25, 0.5, 0.75, 1.0, 1.1 %) for 24 hours. Seed germination, plant growth, character related productivity compared untreated rice. reduced delayed seed germination inhibit shoot root growth early vegetative stage. ability reduce delay doses dependent. more than 1.0% was lethal cenana at 0.75% able increasing sterility. between 0.25 0.5% h soaking inducing Additionally, mutants distinct morphology sterile plant, semi-dwarf, tillering capacity, chlorophyll contents produced this research.
