Overview
Japonica is a variety of rice. Japonica rice needs sunshine time is short, but growing period is long, more cold resistant, sticky rice quality is strong, rice grain is short and round, protein content is higher, taste is good.The character of indica rice is close to that of its ancestor wild rice, so some scholars believe that indica rice is the basic type and japonica is the variant type.
The rice grains of japonica have strong starch stickiness, small swelling, short round grains, dense spikelet length, green leaves, thick color, smooth leaves, strong fertility resistance, short straight leaves, compact plant type, and cold resistance, low light resistance, not easy to drop grain and weak resistance to rice blast and other characteristics. Therefore, the main differences between indica and japonica rice can be summarized as follows: indica rice has long and thin grain, flat cross section, short and scattered spikelet; Japonica rice grain width and thick, cross section round, caryopsis long and dense.
