摘　　要：调查同一组合2个典型株系共10个植株穗粒常规稻颖壳开裂特点及其影响。结果表明:稻谷颖壳开裂粒间表现有轻重之分;品质不同株系籽粒裂颖率存在较大差异,稻穗中部或下部及二次枝梗上的稻谷颖壳开裂现象严重;裂颖稻粒形成的糙米与正常稻粒形成的糙米相比,斑点米、裂纹米、有色米比率及厚度有所增加,而千粒重、长度、宽度减小。According to grain investigation of ten plants of two typical lines of one combination, the characteristics of glumeopening and its effect on rice were studied The results indicated that there were some differences between grains in glumeopening. The rates of glumeopening grains of different lines are of great difference The glumeopening at middle or lower and second branch was seriousThe rates of the specked grains, crabbed grains, and colorful grains, and the thickness of grains of glumeopening were more than those of the normal rice grains while 1000grain weight, length and width of glumeopening grains were poorer than those of the normal rice grains
