In order to comprehensively evaluate and analyze the resistance of Hainan common wild rice to leaf blast and ear neck blast, 2002 common wild rice materials from 11 different cities and counties in Hainan Province were artificially inoculated with leaf blast at the seedling stage and identified by natural disease resistance in the field for two consecutive years in 2022 and 2023, and 995 common wild rice materials that had been pumped were artificially inoculated for ear neck blast resistance.The results showed that：Among the 2002 leaf blast identification materials, 494 (24.68%) were artificially inoculated with anti-leaf blast materials，among which 7 were immune and 17 were highly resistant；In the field, 1160 (57.94%) were resistant to leaf plague, of which 24 were immune and 233 were highly resistant；Among the 995 artificial inoculation and identification materials against ear neck plague, 506 were resistant to ear neck plague, accounting for 50.85%, among which 23 were immune and 136 were highly resistant;The results showed that common wild rice in Hainan was generally resistant to leaf blast or ear neck blast. Most of the resistance resources were semi-erect or inclined,and a few were upright or creeping.Materials with high leaf distemper resistance are also generally resistant to ear neck distemper after heading, and materials with high immune or ear neck distemper resistance are also generally resistant to leaf distemper；A total of 128 common wild rice materials with double resistance to leaf blast and ear neck blast were identified and evaluated.This study provided a reference for the study and breeding utilization of rice blast resistance in Hainan wild rice.
