Effect of Glume-opening Character on Rice Quality of Early Japonica in Cold Region

研究了寒地早粳稻裂颖性状对稻米品质的影响。结果表明,颖壳开裂形成的斑点米、有色米、裂纹米、虫蚀粒均比未开裂的稻谷多,随着裂颖率的增加稻谷糙米率、精米率都随之降低,裂颖率对稻谷的出米率有较大影响。裂颖率与稻米外观品质相关系数较大,呈负相关。

The effect of glume-opening character on rice quality of early Japonica in cold region was studied. The results showed;The number of spot rice,color rice and cracking rice which were formed by glum cracking were more than that of no-cracking rice. With the increasing of the percentage of glume-opening,the brown rice rate and milled rice rate were decreased, Therefore,there was great effect of glume-opening on rice milling quality. There was negative correlation between appearance qualities of rice and the percentage of glume-opening.
