Abstract
By analysis rice quality indexes of 147 late-maturity hybrid rice released by Crop Cultivar Appraisal Commission of Sichuan Province from 2001 to 2010. The results showed that:(1) there existed great difference in the coefficient of variation of different rice quality indexes among different combinations , especially in chalkiness degree and chalky rice rate, whose ratios of meeting the requirement of good quality rice were the lowest. They were main limit factors in Sichuan hybrid rice quality. (2) Long grain type combinations had good appearance quality with lower chalkiness degree and chalky rice rate, but lower head rice ratio; the lower amylose content was, the higher gel consistency was in the combination. (3) The appearance factor, protein content factor, brown rice ratio factor, gel consistency factor and head rice ratio factor were main factors composed to Sichuan hybrid rice quality.关键词
