摘　　要：按Griffing双列杂交(Ⅳ)方法,分析了8个玉米自交系的LWP、RWC、LR、REC、MDA、RS、Pro和Chl与玉米抗旱性相关的生理生化指标在雨养地和水分胁迫下的GCA、SCA及遗传变量。结果表明:生理生化指标受水分胁迫影响较大。RWC以基因加性效应为主,其它均以非加性基因占主导,狭义遗传力低。The general combining ability(GCA),special combining ability(SCA)and hereditary parameter of LWP 、RWC 、LR、REC、MDA、RS、Pro and Chl in8inbred lines of maize under normal condition and water stress are analyzed based on Griffing diallel crossing(Ⅳ).The result showed that RWC is greatly controlled by additive gene efficiency,others are controlled by non-additive gene efficiency.Narrow heritabilities of physiological and biochemi-cal traits is low.
