对二套组合各16个家系的分析表明，母体效应对大麦辐射风代生理损伤有极显著的影响。在由辐射敏感性差异较大的品种组成的组合Ⅰ中，其母体加性效应和母体显性效应均表现为极显著的正向作用，F1代正交组合的辐射损伤极显著低于反交组合，在回交世代中，由F1代作母本的反交组合的辐射损伤极显著低于正交组合。在由辐射敏感性差异较小的品种组成的组合Ⅱ中，母体效应主要表现为极显著的母体显性作用。 An analysis of 16 families from two sets of combinations showed that the maternal effect had a very significant effect on the physiological damage of barley radiated wind generations. In combination Ⅰ, which has a large difference in radiation sensitivity, the maternal additive effect and maternal dominance effect all showed extremely significant positive effects, and the radiation damage in the F1 generation orthogonal combination was significantly lower than that of the reciprocal cross In combination, in the backcross generation, the radiation damage caused by the reciprocal crossover combination of the F1 generation was significantly lower than that of the orthogonal combination. In combination II, which consisted of varieties with less difference in radiation sensitivity, the maternal effect mainly showed extremely significant maternal dominance.
