This paper comprehensive analyzed the 11th main characters such as grain yield , quality and resistance, etc. of 20th new lines of Alpine-japonica rice in Zhaojue by using grey system relational analysis. The results showed that the evaluation result of grey system relational analysis better than general system relational analysis. The evaluation result agreed with comprehensive analysis in field, and the sequencing result of comprehensive analysis agreed with the sequencing result of grain yield. The comprehensive characters of H14 and H3 were best, H2 and H9 were second.
