摘　　要：研究选用5个恢复系、6个不育系按照不完全双列杂交设计,种植于低氮环境下,研究低氮环境对北方杂交粳稻亲本配合力的影响,结果表明:在低氮环境下,参试亲本组合的产量性状间相关性与正常环境一致,表明杂交水稻产量相关性状之间的相关关系基本不受影响。在低氮条件下,一般配合力因不同亲本表现不同,如恢复系H30、H34,不育系150A、9214A部分产量相关性状一般配合力与正常环境表现相反效应。低氮环境下,特殊配合力的表现和正常环境下相比也不尽一致。不管是低氮环境,还是正常环境,一般配合力与特殊配合力都表现一定的独立性。To explore the effects of low nitrogen environment on combining ability of northern hybrid japonica parents through incomplete diallel cross using five restorer lines and six sterile lines planted under low nitrogen environment.The results showed that the correlation between yield traits of parent combinations was consistent with the normal environment and there was unaffected under low nitrogen environment.But general combining ability differs from parent to parent,such as restorer lines H30、H34 and sterile lines 150A、9214A.General combining ability of some yield related traits showed opposite effects with normal environment and the same as special combining ability.They all showed certain independence whether in low nitrogen environment or normal environment.
