Abstract: Mixed planting of the two cultivars between Kendao 12 and Suigeng 4, retained the excellent qualities of the strong tillering of Kendao12 and the flavor of Suigeng 4, and overcame the disadvantages on soft straw of Kendao 12 and poor tillering ability of Suijing 4. This paper studied the effects of different mixed planging ratio between Kendao 12 and Suigeng 4 on rice yield and quality. The results showed that mixed planting ratio of 4∶6 between the two varieties could improve the lodging resistence, increase the tiller number, the yield reached 9 233.55 kg/hm2, and the taste reached 87 points.

Key words: japonica rice, mixed planting ratio, yield, quality
