%X Soil phosphorus (P) deficiency is a major yield-limiting factor in rice production.Employing 526 rice landrace accessions from 5 rice-planting regions and 16 prefectures in Yunnan Province,this paper studied their P-deficiency tolerance characteristics by comparing the relative plant dry weight under acid red soil condition.The results showed that Northwest Yunnan cold highland japonica rice-planting region was most abundant in P-deficiency tolerance core collection of indica,and there was no significant difference in japonica among five ecological zones of rice landraces.Nujiang,Lijiang,Dehong,Wenshan,Xishuangbana and Yuxi were most abundant in P-deficiency tolerance core collection of indica,and Lijiang,Wenshan and Chuxiong were most abundant in P-deficiency tolerance core collection of japonica.Indica had a higher P-deficiency tolerance than japonica.The P-deficiency tolerance of rice was significantly related with its genetic diversity,rice breeding and acid red soils.
