Abstract: The correlations between amylose content and 1000-grain weight in early season indica rice varieties were studied by both sowing-date experiments and controlled ripening temperature treatments. The Correlation coefficients in all the four non-waxy varieties, namely Hong 410, Zhong 83-49, D6033 and Hongtu 31, were found to be significantly positive and in the one waxy variety, Xiangfu 81-10, was very significantly negative. It suggested that the amylose content related with the filling degree of grains.
