| Abstract: | The experiment results show that in dry conditions, the rice is transferred between the different intergeneric materials, including the descendants of the different recipient parent, single plant grain yield and agronomic traits is closely related to the plant effectively panicle number, panicle length, number of secondary branches per panicle grain number,seed setting rate and grains per panicle related to effective yield per plant is also greater; the results of direct assessment and selection of field drought resistance materials provided. |

| Keywords: | dry conditions the material rice which is transferred between the intergeneric material agronomic traits yield per plant correlation |
