[Objective] To investigate the effects of proportion of dry matter of different organs in whole-plant dry matter on neutral detergent fiber(NDF) content in silage corn.[Method] A total of 36 crosses were developed from nine inbred lines,according to complete diallel crossing design.The NDF contents and proportion of dry matter in different organs were statistically analyzed.[Result] The NDF contents were significantly different between different organs of silage corn,and the proportion of dry matter and NDF content had significant correlation in different organs.The whole-plant NDF content was positively correlated with the proportion of dry matter in straw,stem and leaf as well as bract and spike-stalk,but it was negatively correlated with the proportion of dry matter in ear.[Conclusion] To reduce NDF content in straw and to increase grain yield are efficient ways to improve quality of silage corn.
