It is well known that ion beams have dramatic mutagenic effects[1].The reason why heavy ions are more suitable for induced mutagenesis is well explained by Liu et al and Tanaka,et al.[2-3].Liu et al think that energetic ions can penetrate through the seed coat and cell envelope and induce strand breaking of the DNA.Tanaka et al highlight that more than the mutation rate per dose,the number of mutations should be considered for the most suitable mutagen selection.As feedstock for fuel ethanol,sweet sorghum[Sorghum bicolor(L.)Moench]is a C4plant characterized by a high photosynthetic efficiency and a high bio-
It is well known that ion beams have dramatic mutagenic effects [1]. The reason why heavy ions are more suitable for induced mutagenesis is well explained by Liu et al and Tanaka, et al. [2-3]. Liu et al think that energetic ions penetrate through the seed coat and cell envelope and induce strand breaking of the DNA. Wanaka et al highlight that more than the mutation rate per dose, the number of mutations should be considered for the most suitable mutagen selection. As feedstock for fuel ethanol, sweet sorghum [Sorghum bicolor (L.) Moench is a C4plant characterized by a high photosynthetic efficiency and a high bio-
