Abstract: In order to reduce rice breeding test costs, the authors studied the effects of fishing and new Japonica rice varieties selection in high altitude rice-fish fields on the basis of previous trials and the successful experience of rice-fish cultivation.The results showed that in trial fields, rice yields were 575.1 kg/667 m2, rice price was high, fish yields were 40.6 kg/667 m2, increasing benefits 1493.3 yuan/667 m2, in surrounding fields, rice yields were 645.2 kg/667 m2.
