超大穗小麦是小麦超高产育种的宝贵资源。通过去穗处理，对不同类型的超大穗小麦灌浆特性进行了方程拟合及参数分析,结果表明：①百粒重的增重进程，在不同处理间无显著差异,不同品系间差异明显；②单株粒重的增重进程，在不同处理间、不同品系间都表现出显著差异,不同处理间更为突出；③对灌浆参数分析，超大穗小麦的最大灌浆速度与对照基本一致，但灌浆期显著的长，86（306）达50 d、90（151） 43 d，而对照小偃6号、咸农151分别为40 d、35 d。依次配合相应的栽培技术，可有效的发挥超大穗小麦产量潜力。

The super large spike wheat is valuable resource for the super high yield breeding.By mean of the cut spike test.The Logistic equations were used to describe the grain filling process and the grain filling parameters were analyzed for different varieties of the super large spike wheat.The results as fellows:① In the process of the 100 grain weight filling,the difference between the different treatment is not significant and between the varieties is significant.② In the process of the plant grain weight filling,the difference between the different treatment and different varieties are all significant.③ By analyzing the parameters of grain filling，the maximum grain filling rate are the same among the test varieties,the period of grain filling are very significantly difference.86(306) is 50 days,90(151)is 43 days,the CK,Xiaoyan No.6 and Xiannong 151 are 40 and 35 days.
