Abstract：Wheat cross usually causes hollow kernels and small grains.In order to find a way to solve this problem,kraft paper bags and white sulfuric acid paper bags were used to cover the cutting glume spikes of 66 wheat cross combinations and study the effects of two kinds of paper bags on the grain number per spike and thousand kernel weight.As a result,no significant difference was found in the grain number per spike be-tween two different treatments.However, the thousand kernel weight under covering kraft paper bag was ex-tremely significantly higher than that under covering white sulfuric acid paper bag,which increased by 33.00%averagely in 66 wheat hybrid combinations.It indicated that using kraft paper bag to replace the traditional white sulfuric acid paper bag would significantly increase the thousand kernel weight of wheat hybrid seeds.
