Variety traits
1000-grain weight of rice
Oryza sativa L.
A physical indicator of rice grain plumpness and density, ranging from 15 to 43 g, which determines seeding rates, seed quality, and processing efficiency.
In the reference 38 varieties crop Rice, where this is mentioned in the description.
The 1000-grain weight (TGW) value in rice depends on the cultivar type: japonica rice typically has an average weight of 24–28 g, while indica rice ranges from 18–22 g. When evaluating grain quality, values below 28 g are classified as small, whereas values in the range of 32–36 g are considered optimal for achieving high yields.
This indicator is critical for managing stand density when calculating weight-based seeding rates and assessing plant productivity potential. A high TGW contributes to a higher yield of whole kernels during milling, while low values often indicate grain shriveling and lead to an increased percentage of broken kernels during processing.
