摘　　要：沈阳89－366是偏矮秆粳稻，与粳、籼、爪哇3种类型品种杂交，F1代结实率与亲本无显著差异，具有广亲和性，与爪哇型品种杂交F1代优势性状多而强，与偏矮秆品种杂交F1代株高半矮秆，是水稻超高产杂交育种有应用前景的新种质。Shennong 89-366 is a dwarf tending Japonica rice. The F1 generations of Shennong 89-366 with Japonica,Indica of Javanica rice showed no evident difference in setting percentages indicating that Shennong 89-366 is ofbroad compatibility. More favorable vigorous traits were developed in the F1 of Shennong 89-366 with Javanica rice.The F1 of it with dwarf tending varicties was semi-dwarf. Shennong 89-366 is a prospective new germplasm forsuper-high-yield cross breeding in rice.
