Abstract
A low starch viscosity mutant of rice (Oryza sativa L.), labeled as lsv-1, was induced by gamma irradiation. The starch-related quality of the mutant and its parent variety W8-1 were characterized. The apparent amylose content (AAC), gel consistency (GC), and alkali spreading value (ASV) of lsv-1 were similar to W8-1. However, the major starch viscosity parameters of lsv-1 starch, i.e. peak paste viscosity (PKV), cool paste viscosity (CPV), breakdown viscosity (BDV), and setback viscosity (SBV) were significantly lower than that of W8-1. Furthermore, lsv-1 had a shorter peak paste time (PKT) and higher pasting temperature (PT), compared to the parent variety. The feature of the pasted rice flour and morphology of starch granules in the endosperm of lsv-1 were also different from the parent variety.
