This study aims to improve local rice genetic West Sumatra to acquire properties that are superior (more early maturity) through mutation breeding. This study was conducted from April 2009 to December 2010. In 2009 screening at the stage orientation doses M1 to obtain a dose treatment is effective in generating genetic diversity is very valuable in the selection effort. In 2010 the selection in a population of M2 to getting properties older than early maturing crops (early maturing mutant). The results showed that the treatment irradiation dose of 200 Gy is the dose that is effective in generating genetic diversity. At these doses have formed extensive genetic diversity for the variable character of the age and height of the plant. With the extent of genetic diversity of the resulting mutant candidates that can be selected at this stage of M2. From the selection made at the stage of early maturing mutant M2 candidates obtained as many as 86 candidates with the mutation frequency of 0.14%, as well as short mutant (dwarf) and a semi-short (semi-dwarf) were 97 mutants with mutant frequency of 0.16%. Candidates mutant is a mutant candidates promoting to have better character as a result to be developed in the future
