试验选用9份自交系，按格列芬双列杂交方法Ⅱ设计。对4个阶段灌浆速率配合力分析并结合产量对自交系和杂交组合进行综合评价。结果表明: 第Ⅰ、Ⅱ、Ⅲ、Ⅳ期灌浆速率的配合力自交系间有较大差异；同一自交系及同一自交系的不同杂交种4个时期的灌浆速率也有较大差异。HR705自交系4个阶段均较低；Mo17第Ⅰ、Ⅱ期较低，第Ⅲ、Ⅳ期较高；HR11前3期较高，第Ⅳ期较低；黄早四4期均高；HR304前两期较低，后两期较高；丹340Ⅰ期较低，其它3期均高；HR112 4期均高；K10第Ⅰ、Ⅱ期最高，Ⅲ、Ⅳ期较低；HR106的4期均较低。灌浆速率一般配合力高的自交系其特殊配合力也较高，一般配合力低的自交系也有特殊配合力较高的组合出现，因此有必要重视特殊配合力。

Nine inbred lines were used to mating crosses by Griffing's design 2 ,the combining ability of grain filling ,the correlation with yield were analyzed. The main results are discussed in the following: The significant differences of combining ability of grain filling were observed among inbred lines in the four stages of grain filling. There were also have significant differences in the same inbred line and hybrid among the four stages of grain filling, inbred HR705 was lower in all of the four stages. Inbred Mo17 had lower combining ability at the stageⅠand stage Ⅱ, but having higher combining ability at the stage Ⅲ and stage Ⅳ. The combining ability of inbred HR11 was higher in the first 3 stages and lower in the last stage. Inbred Huangzaosi had higher combining ability in all of the four stages. Inbred HR304 had higher combining ability in the first 2 stages and lower combining ability in the later stages. The combining ability of inbred Dan340 was lower at the stageⅠand higher at other stages. The combining ability of inbred HR112 was higher in all of the four stages. The combining ability of inbred K10 was lower at the stageⅠand stage Ⅱ, higher at the stage Ⅲ and stage Ⅳ. Inbred HR106 had lower combining ability in all of the four stages. The special combining ability of filling rate was higher in the lines with higher general combining ability of filling rate. There were also many hybrids with higher special combining ability but the general combining ability of their parents was lower. We should pay much attention tospecial combining ability in the breeding.
