Abstract: Taking Fudao88, Exiang No2 high quality rice varieties as materials, such as selection of 11 quantitative index as evaluation factors, using the grey correlation method, the effects of various characters on the suitability of the rice variety were analyzed, and the suitability of the variety in the model of rice shrimp was evaluated comprehensively, so as to provide scientific basis for the breeding of high quality rice and the popularization of agricultural technology in the model of rice shrimp co-cropping. The results showed that among the tested 20 rice varieties, 6 varieties had the greater weighting correlative degree with the reference variety, and they were suitable to be used for rice-shrimp co-production model.

Key words: rice-shrimp co-production, high-quality rice varieties, grey correlation degree analysis, variety screening
