Abstract: 138 plants of F1anther culture for 3 crosses derived from "paddy rice/dry field rice"were treated under the condition of water and land culture in this study,respectively,japonica rice germplasm resource screened according to drought tolerance and high yield,meanwhile,indica-japonica type anlyzed and drought tolerance identified for these progenies,these results indicated one of bi-parents showed drought tolerance,about 50 percent progeny plants from anther culture was "drought tolerance type".The drought tolerance of most progeny plants was continuous distributed,individual progeny plant show bidirectional segregation beyond parents for drought tolerance,it was controlled by micr-multiple gene.Most plants from 3 combinings showed rice japonica type on N6 culture media,less indica type.Finally,Index of rice drought tolerance identification was being discussed.

Key words: Japonica rice, Anther culture, Germplasm resource, Drought tolerance
