In generally, it can be concluded that out of seven studied grain quality c~aracters, only three characters were affected significantly by storing rice in different storage packages. The changes of these characters started after 6 months storage period i.e. yellow and cracked kernels percentage, and after 9 months for protein content. Further storing rice in carton boxes exhibited the better changes in the means of these characters, meanwhile, plastic bags and / or paper bags gave the worst values. In additi
