Abstract: Yield and population growth quality of colored rice were studied under five different densities with two colored rice of black glutinous (Y4) and red japonica (Y5).The results indicated that the density influenced yield mainly by changing the number of effective panicles. The 4×104 plant/666.7m2 treatment had a significant lower yield than the other treatments. The treatment with a density from 12×104 ~ 16 ×104 plant/666.7m2 had a higher yield and effective tiller rate. It is concluded that properly increasing the density was beneficial to improve the yield and to construct the population growth quality of colored rice. The suitable density of Y4 and Y5 is respectively 12×104 plant/666.7m2 and 16 ×104 plant/666.7m2, moreover, the durability to density of Y5 is stronger than Y4.
