Pasting properties of 35 traditional (Japonica) and 23 high-yielding (J/Indica) rice varieties having various hydration rates at 23℃ were investigated. Amylograms showed that high-yielding rice varieties had higher values for peak (P), hot-paste (H) and cold-paste (C) viscosities than those for traditional rice varieties. P had a highly negative correlation with H/P. C/P and C/H. P of traditional rice varieties was positively and negatively correlated with protein amylose contents, respectively. However, H and C showed no correlation with protein or amylose content. No correlation was observed between amylograph indices and hydration rate of rice grain.
