Abstract: The grain quality of 6 early and 5 late indica rice varieties cultivated both in early and late seasons was studied. The result showed that an obvious difference between the two growth seasons existed in milling, appearence and cooking qualities. The grain quality of late seasonal culture was remarkably better than that of early one with respect of smaller chalkiness, better translucency and higher head rice yield. The quality of late varietites become poor when they were cultivated in early season, due to the effect of high temperature in the period of filling stage. The target and method of quality improvement in indica rice were discussed.
